Gdb Set Sysroot Example

c: No such file or directory. Item types are used to normalize the GDB_Items table (the type of an item in the GDB_Items table is represented as a UUID), to provide better support for future geodatabase functionality enhancements and define a type hierarchy. json ,generate launch. The length of the fields f2 and f3 are each 788 bytes. developerWorks blogs allow community members to share thoughts and expertise on topics that matter to them, and engage in conversations with each other. Varun December 6, 2015 Breakpoints and Backtrace traversal – gdb debugger Tutorial & Examples 2015-12-06T11:10:29+05:30 Debugging, Debugging Tutorial, gdb, gdb commands, gdb Tutorial No Comment In this article we will discuss how to use breakpoints in gdb and check backtrace etc. and all your stack frames look like this: 0x40000780 in ?? gdb is trying to tell you that it cannot find the relevant ld library for the target it is debugging. You can browse for and follow blogs, read recent entries, see what others are viewing or recommending, and request your own blog. In that case, two software components are required, one on the target and the other on the host PC. 828 Fall 2014 Using the GNU Debugger September 10, 2014 13 / 14. GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code. setenv-android. Quit from gdb You can access list of all gdb commands with their description here. Hi, Sorry for the confusion. Since it is based on GDB, it can be used through a JTAG or an ethernet link with gdbserver. gdb ↔ gdbserver path through Ethernet, used for Cortex-A7 Linux applications. My distro is Ubuntu 12. This comes from the Magenta build and sits in the sysroot subdirectory of the main Magenta build directory. The libtool script does some magic so that the applications will run using the shared libraries in the build directory, instead of any libraries installed on the system. First lets create an unordered_map and then we will see the different ways to iterate over it. For example, suppose you have a compiler which runs on a GNU/Linux system and generates ELF programs for a MIPS embedded system. When the option --vgdb-shadow-registers=yes is given, the Valgrind gdbserver will let GDB examine and/or modify Valgrind's shadow registers. thbreak args Set a hardware-assisted breakpoint enabled only for one stop. Run openocd. To use GDB for debugging apps and processes: Set up environment with the envsetup. Configuring Eclipse for JTAG Debugging. Inside GDB, your program may stop for any of several reasons, such as a signal, a breakpoint, or reaching a new line after a GDB command such as step. Rustup could for example set an environment variable that Cargo (and rust-gdb!) would read to know where to find std sources. Running our example again, it will only trigger and stop the debugger if a write access happens with zero. For example : $ gdb -- NetBeans v8. It's only supposed to check that python-gdb. See section Break conditions. Otherwise the default value will be "" and you might need to set it manually if you are debugging remote processes. Incidentally this is what buildroot does using a wrapper, when using an external toolchain. fittings -p sde. Gdb + gdb server + socat 1. Do you need "set solib-search-path" or "set sysroot"? When remotely debugging applications the same binaries need to be available on the host running GDB. DevOps Services. Tutorial of gcc and gdb. In next section, you will do your first debugging session and will learn how to use GDB. Incidentally this is what buildroot does using a wrapper, when using an external toolchain. I found the online wiki did not work for OMAP-L137 thus documented the changes I made to get things functional. Starting GDB Start up GDB to debug a program "gdb executable" "gdb -args executable arguments" Or else just start "gdb" and then use commands - "file executable", "set args arguments" Then start up program via "run" - May want to set breakpoints first Attach GDB to an already running process "gdb executable pid. A working example is provided below. Building and cross-compile tutorial Saturday, December 6, 2014. Once brickstrap has finished creating the root filesystem, you can get a bash shell inside of the directory that was created. Lastly, you can tabbing the function name that you want to debug (usually you are looking for some Java_* entrypoint), and then you can set a break point on such function:. Setting target-file-system-kind to dos-based tells gdb to interpret such file names similarly to how the target would, and to map them to file names valid on gdb 's native file. 2 is recommended because it has some bug fixes for the pretty-printing. Copy the core file to your development PC into the OpenEmbedded sysroot and use gdb to do the analysis:. Seems like its using the local x86 gdb (host computer running windows) Does not seem to be a way to specifie using arm tool chain arm-none-eabi-gdb. You set the watchpoint after the program breaks. 0x008f6c88 in ??. That's pretty fundamental, but what it never actually tells you how to do is pass flags to your C compiler. Install the GDB Hardware Debugging plugin. The debugger needs a substitute path to find the sources. Using qemu user mode to run cross-compiled binaries Dec 14, 2016 The qemu CPU emulator is typically used to emulate an entire system, for example we can use qemu-system-arm to start a simulated ARM-based machine, boot Linux, and then run whatever software is appropriate. You can use any port number in place of "1234" as long as you use the same number on host and target system. 50) the "set follow-fork-mode child" command does nothing. A cross gdb can be used to analyse a core file. You may then examine and change variables, set new breakpoints or remove old ones, and then continue execution. GDB will silently watch the program in the background. He is off work at the moment and I am in a rush for this. Additionally if you want to check list of currently set breakpoints, you can use info break command. gdb ↔ JTAG/SWD path through OpenOCD and ST-LINK, used both for Cortex-M4 firmware and Cortex-A7 Linux kernel. In the example below we can see that breakpoint number 2 has been disabled (there is an 'n' under the Enb column). I'm used to setting up things written in Python, C, C++, with very simple yet powerful configuration mechanisms, and an easy to discover what's wrong when something bad happens. warning: Unable to find dynamic linker breakpoint function. The current stable version is valgrind-3. This tutorial shows how to build and debug a "Hello world" application for Raspberry PI on Windows. GDB Hardware Debugging. To debug your Cygwin or MinGW application, add the miDebuggerPath property and set its value to the location of the corresponding gdb. With the Oracle Solaris operating system, unhandled signals such as a segmentation violation, illegal instruction, and so forth, result in a core dump. On this dialog there is a "Backtrace" tab that, when loaded, calls gdb and makes it load the data and generate the full backtrace on the behalf of the user, showing it in the main text box and allowing it to be saved directly to a file. 5 steps to setup and use a debugger with the Particle Photon A lot has been written about debugging with GDB, so here’s my little summary. Sometimes adding another source path is not enough if you have complex hierarchy. -I dir This specifies a directories for the compile to search for when looking for include files. Example: Publish a map service from a map document (MXD). * New commands eval template, expressions. Don’t forget to refer the test program, build and debug session examples too. For example, if the fourth call to a function is the one that fails, you can use "c 3" to skip the first three calls. The following is an example of running the sdegdbrepair –o repair_tables command to repair a single table. Note that for GDB 8. You can use this database to “ try your wings ”. /bin However, if I close that and open Nsight Eclipse, sysroot is set back to target. 156: n/a # #0 0x00003fffb7dd1798 in PyObject_Print 157: n/a 'set print address off', 158: n/a: 159: n/a 'run'] 160: n/a: 161: n/a # GDB as of 7. MX31 PDK, refer to the i. Setting target-file-system-kind to dos-based tells gdb to interpret such file names similarly to how the target would, and to map them to file names valid on gdb 's native file. warning: Unable to find dynamic linker breakpoint function. I copied the core dump file and tried to get the backtrace using arm-gdb on x86_64 host. Python enabled gdb on Windows and relocation a kind of "sysroot"ed gdb+python, so > Leaving such a value for PYTHONPATH set while gdb's python is running. Set the gdb command, for example arm-none-eabi-gdb, and select “OpenOCD (via pipe)” as JTAG device. The GNU Debugger GDB is the most common debug tool for Linux. GDB Pretty-Printers, ELF and GDB again ELF symbols versioning, gdbserver usage Red Hat Author Jan Kratochv´ıl February 18, 2012. (gdb) break test Function "test" not defined. si (or stepi) Execute one machine instruction. Perform any actions necessary to reproduce the crash. These settings can either be switched on in at the GDB command line, or put into a. exe for your Cygwin or MinGW environment. Updating Sysroot for Raspberry PI Cross-Toolchain. arm-none-eabi-gdb BINARY. Write a sample C program with errors for debugging purpose To learn C program debugging, let us create the following C program that calculates and prints the factorial of a number. Don’t forget to refer the test program, build and debug session examples too. Start debug as you need. How can I set sysroot in Nsight Eclipse? Below are the warnings:. (gdb) set pagination off. Meanwhile, it is likely that GDB is unable to debug shared library initializers or resolve pending breakpoints after dlopen(). First build a cross-gdb on your host machine (inside the chroot). Get a guide dog, donate to GDB, become a volunteer links. Which gdb version to use?. This set of commands is available only when debugging the Cell/B. ARMulator I was made open source and is the basis for the GNU version of ARMulator. When we call mod_add_func(12,15) it is equivalent to calling add(15, 12). 0\Samples\Data\dbdemos. For example, on the DSU, only two data breakpoints can be set at a time, and GDB will reject this command if more than two are used. The server is usually an executable running on the same machine, but it can run anywhere in the network too on a remote machine. 1 ArcMap 10. It is not obvious from the documentation and it is not googled easily either. We are creating here a sysroot for Raspberry Pi cross compilation in our computer. Using Insight for Application Debugging This section describes how to use the Insight GUI in all application debugging scenarios, including the analysis of a process dump. 5 ((10+5)/2). It can be used both for programs written in high-level languages like C and C++ and for assembly code programs; this document concentrates on the latter. We will create a basic “Hello, World” application using the GTK+ toolkit and will show how to build it on Windows, debug it and view the source code of the GTK functions on the call stack. *NOTE* You may notice in the example below that the line of code printed doesn't match with the line that changes the variable x. This program is writtten to compute no. C/C++ DSF GDB Debugger Integration To set up a project for remote debugging, you need to. JDB support is experimental. (gdb) break 5 No symbol table is loaded. You’ll see a prompt (gdb) – all examples are from this prompt. Two commands are required: (gdb) b 29 Breakpoint 4 at 0x804844f: file gdb_use. show solib-absolute-prefix Display the current shared library prefix. Example: Publish a map service from a map document (MXD). To delete specific features from a feature class, convert the feature class into a layer using Make Feature Layer or by adding it to the display. The commands instruction tells gdb to set a particular number of commands and to report them to you. These settings can either be switched on in at the GDB command line, or put into a. Our dogs are trained with positive reinforcement methods that use high value rewards of both food and praise. GDB contains a large repertoire of commands. Once the program is stopped you can examine and change the variable values, continue the program execution from that breakpoint, etc. Get a guide dog, donate to GDB, become a volunteer links. To debug your Cygwin or MinGW application, add the miDebuggerPath property and set its value to the location of the corresponding gdb. py commands work as expected: stderr should be ignored. The process is a bit laborious, but I can work out how to script it later (this is presumably what Eclipse is doing). Because I saw examples in YouTube GDB tutorials utilizing books, I decided to use my own book data. Prerequisites. It also requires a big amount of free disk space. GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code. Do you need "set solib-search-path" or "set sysroot"? warning: Unable to find dynamic linker breakpoint function. gdb ↔ gdbserver path through Ethernet, used for Cortex-A7 Linux applications. * terminal_emulator. show debug-file-directory Show the directory GDB searches for separate debugging information files. For example:. It describes the steps required to run the Allegro demos and examples on an Android device. For example:. gdb ↔ JTAG/SWD path through OpenOCD and ST-LINK, used both for Cortex-M4 firmware and Cortex-A7 Linux kernel. Disclaimer: This article is still a draft. In the SDK, i686-nacl-gdb is an alias for x86_64-nacl-gdb, and the newlib and glibc toolchains both contain the same version of GDB. 0x4012d8fc in ??. It does not need any modification of the Arduino board or external hardware. Otherwise the default value will be "" and you might need to set it manually if you are debugging remote processes. txt (gdb) handle SIG33 pass nostop noprint (gdb) set pagination 0 (gdb) run The program will start. Unfortunately that means it also won't work in WinGDB. So it stopped execution when it reached line number 17. Inside GDB, your program may stop for any of several reasons, such as a signal, a breakpoint, or reaching a new line after a GDB command such as step. One can use the OpenEmbedded built cross gdb and the target sysroot for that. This tool accepts layers with selections as input and will delete only those features that are selected. This tutorial shows how to update your sysroot directory for the Raspberry PI cross-toolchain. For example, cuda-gdb could be configured to connect to remote target as follows: (cuda-gdb) set sysroot remote:// (cuda-gdb) target remote 192. Delete or disable unused hardware breakpoints before setting new ones (see section Disabling breakpoints). c arg gdbを使ってアドレスを行に変換する gdb set arg (2) OPごとに、GDBのアドレスからソースコード行を見つけるコマンドは次のようになります:. Set up a geodatabase in Oracle. GDB Hardware Debugging. When an attribute domain is associated with a table or feature class, an attribute validation rule is created in the database. A set of GDB macros are distributed with Python that aid in debugging the Python process. My CMake-toolchain-file is OK, header-files and most of the libraries are correctly detecting inside my sysroot-mount. AIS Data for 2012. Run command on breakpoint without stopping. $ gdb -ex "set use-deprecated-index-sections on" Instead you must do, for example, $ gdb -iex "set use-deprecated-index-sections on" There are currently some limitation on indices. The program stops when it reaches a breakpoint, and you can run gdb commands to inspect it or change variables before allowing the program to continue. I'm used to setting up things written in Python, C, C++, with very simple yet powerful configuration mechanisms, and an easy to discover what's wrong when something bad happens. The intended audience is students in the first week or two of a computer systems/assembly language course. (gdb) br 12 Breakpoint 1 at 0x1045c: file intAndFloat. Prerequisites. e GDB) to locate the erroneous statement, and repair it. gdb is the GNU Debugger, the standard debugger on Linux. Simply pushing the return key will repeat the previous command, and li is smart enough to display the next (up to) ten lines. Do you need "set solib-search-path" or "set sysroot"? From To Syms Read Shared Object Library. I configured GDB with --with-sysroot, declared additional set sysroot, set solib-search-path, set solib-absolute-path (nevermind alias of set sysroot). Hi everyone, I encounter a bug while compiling MathGL with pthread enabled. Here you'll see how and where. Weaksauce, following gdb's advice didn't help. I want to cross-compile C++-applications for the raspi using the rpi-tools, CMake and a raspbian sysroot I'm exporting via nfs from a running raspi. Source: gdb Source-Version: 7. c:5 3 breakpoint keep y 0x080483da in func1 at test. ターゲットとCodeSourcery IDEでgdbserverを使用しています。 私のハードウェアはomap3530のgumstixです。 私は主なアプリケーションでコードをステップ実行することができますが、共有ライブラリの関数にステップインしようとすると、メモリアドレスが取得され、デバッガが終了します。. The ‘Ignore count’ can be used as a ‘count-down’ until it triggers, for example I can catch the 3rd time when the access and condition is true. In this example you'll use the default domain name mylinkit. 2 on port 2345. When your program stops, GDB spontaneously prints the line where it stopped. An abundance of rewards, including physical and verbal affection, builds motivation and confidence, and creates a happy working guide dog. Running our example again, it will only trigger and stop the debugger if a write access happens with zero. Read on for tutorials on debuggers like GDB and Visual Studio, as well as more exotic and powerful tools like Valgrind. Do you need "set solib-search-path" or "set sysroot"? warning: Unable to find dynamic linker breakpoint function. print expr. Additionally to the core dump gdb needs the executable and all linked static object files. See the file COPYING or. Below document will hopefully save others some work. out, but does not run the program. Example: Simple Hello world project, additional lib freetype and jpeg (they should exists host-sysroot), linked to binary. However, if I try to backtrace a segfault, or some similar problem, I always get only the message "No Stack". To run an application with GDB, you have to run GDB through libtool, like so: $. This page explains the set auto-solib-add command. SEE ALSO `gdb' entry in info; Using GDB: A Guide to the GNU Source-Level Debugger, Richard M. For example, /build-magenta-pc-x86-64/sysroot. The-thread-list-ids Command Synopsis-thread-list-ids Produces a list of the currently known gdb thread ids. c:38 (gdb) list #--- let's see code around segfaulting instruction 10 int initfunc(int *array, int len) { 11 12 int i. The only exception to this rule would be to utilize the service admin api to publish a map document up to the server. If you have ever used a debugger you are probably familiar with the concept of breakpoints. , using a debugger to trace the execution of the child process instead of (or in addition to) the parent. when an assertion fails). If the automatical detection is failed, please set the value explicitly. To supply arguments to the parallel tasks, use the gdb command run args or the gdb option -args. It also requires a big amount of free disk space. Below document will hopefully save others some work. The symbol file and target libraries must exactly match the executable and libraries on the target, with one exception: the files on the host system should not be stripped, even if the files on the target system are. If QEMU has multiple virtual CPUs, this halts all of them. kill Kill the running program. gdb — Working with GDB¶. Here's a better. py helper script, but it's not working as expected. This page explains the set auto-solib-add command. In the above example, set sysroot from MPSS installation in. js (via GDB) Java. It supports g++ compiler for c++. In next section, you will do your first debugging session and will learn how to use GDB. I cannot open any of them with. The green program counter arrow appears on top of the breakpoint icon of the function breakpoint. I was just lacking a little GDB knowledge (I much prefer graphical debuggers). (gdb) run Starting program: /path/example Program received signal SIGSEGV, Segmentation fault. I then modified the library, rebuilt. Note: Remember to add the --prefix=/mypath and --with-sysroot=/mypath flags to match the binutils build if you are using a sysroot. [Switching focus to CUDA kernel 0, grid 2, block (0,0,0), thread (0,0,0),. Prerequisites. Set environment EF_PROTECT_BELOW or EF_PROTECT_FREE or EF_ALLOW_MALLOC_0 or EF_FILL in order to debug various problems. If your GDB binary was compiled with the --sysroot argument, you won't need to run the set sysroot command - the sysroot will be automatically set to the location specified during compilation. Or maybe have a conventional path relative to the rustc binary. This section will demonstrate how to use GDB commands by going through example. py helper script, but it's not working as expected. Notes on selected gdb commands: Break: To set a breakpoint on a line, issue the break command with a line number. Home of the Chromium Open Source Project. (gdb) b factorial (gdb) b 23. Finally, I demonstrate how we can set up a cross-debug environment, where we use gdbserver on the arm device and gdb-multiarch on the client device to establish a full debug environment. 1 or later is needed for this to work. You can set the default system root by using the configure-time `--with-sysroot' option. Make breakpoint pending on future shared library load? (y or [n]) n (gdb) info sharedlibrary warning: Could not load shared library symbols for /tmp/libTest. Material from the CS:APP Textbook. Variable toolchain_sysroot_dir in that file shouldn't be set for baremetal toolchain testing. Use the debugger(i. I can set sysroot when running cuda-gdb located here: /usr/local/cuda-10. In this case the GNU/Linux system is the host, and the MIPS ELF system is the target. If you discover any rendering problems in this HTML version of the page, or you believe there is a better or more up-to-date source for the page, or you have corrections or improvements to the information in this COLOPHON (which is not part of the original manual page), send a mail to [email protected] What you need in a sysroot will depend on what you are doing. Set GDB substitution rule. Newer versions of GDB will also support Python scripting and through that provide a very powerful set of tools to debug, even just from the command line. Often, during cross-compilation, builds are mixed of tools to use on the host, and libraries to install on the target, making it unfeasible to simply set PKG_CONFIG_SYSROOT_DIR during the build. Make breakpoint pending on future shared library load? (y or [n]) n (gdb) info sharedlibrary warning: Could not load shared library symbols for /tmp/libTest. Please have the device up and running before you start the Qt Creator Configuration steps, as the (SSH) connectivity to the target device will be tested by the Qt Creator. I tried setting sysroot to the path of the copy using the command window, but I got the same warnings. I am using the uppercase example from the BOINC samples in order to build BOINC app for android. 5, “Setting a New Breakpoint”, you can display the list of currently set breakpoints by running the following command: (gdb) info breakpoints Num Type Disp Enb Address What 1 breakpoint keep y 0x00000000004004e5 in main at fibonacci. (If you don't add breakpoints, the GDB debugger will not have a reason to suspend execution so that you can debug). The GDB (DSF) debugger integration uses absolute paths to set breakpoints, while the Standard one uses relative paths (I think). -L dir To specify directories for the linker to search for the library files. Since all of gdb is all in one window, when you are debugging you cannot see the source code for your program. b *addr (or breakpoint). The direct connection is set up in the instance property. This option will let you use the Java debugger (jdb) to debug the native Java portion of Fennec. I am using the uppercase example from the BOINC samples in order to build BOINC app for android. Data is the king. Use set sysroot to locate target libraries (unless your GDB was compiled with the correct sysroot using --with-sysroot). /Programs/python. You need to tell GDB how to access to your program’s binaries with a set sysroot command, you need to obtain a local copy of the main executable and supply that to GDB with a file command, and you need to tell GDB to commence remote debugging with a target remote command. How can I set sysroot in Nsight Eclipse? Below are the warnings:. Enter the Simple Chrome environment. I've tried to use the GDB 7. If you have a large backtrace, you can log gdb output to a file (the default is gdb. They only work when: for DWARF debugging information, not stabs. Remote Debug via GDB/gdbserver. gdbinit example: Set a breakpoint on GDB entry point for stripped PIE binaries without disabling. Py_Finalize; Py_Initialize; Py_Initialize; Py_Initialize; Py_Initialize; Py_Initialize; Py_Initialize; XrmInitialize; ac_fn_c_check_decl. GDB Tutorial A Walkthrough with Examples CMSC 212 - Spring 2009 You can set as many breakpoints as you want, and the program (gdb) print/x my var GDB Tutorial. In that case, two software components are required, one on the target and the other on the host PC. GDB has a new "set sysroot" command which does the same thing, and that's very handy. 3, so we’ll have to resort to the display command. The sysroots are installed in the Azure Sphere SDK installation folder. It is highly recommended to update the sysroot after downloading the toolchain, or after switching to a new SD card image. txt (gdb) set logging on Copying output to gdb. It assumes that the library of standard stklib modules is located in. DevOps Automation. Configuration of OpenOCD software and set up JTAG adapter hardware that will make together a debugging target. For x86 and amd64, GDB version 7. In this case you may find the following information useful. Debugging PNaCl pexes (Pepper 35 or later) If you want to use GDB to debug a program that is compiled with the PNaCl toolchain, you must have a copy of the pexe from before running pnacl-finalize. In this case you can add substitution rule for source path with set substitute-path GDB command. outside of the Buildroot tree, using the br2-external mechanism. You can now run any of the standard gdb debugging commands on hw_exe. Weaksauce, following gdb's advice didn't help. So for example this variables might take value: cpu=arcem-mnorm. A must-have for any serious programmer. monitor set ignore-ondemand gdb> monitor set ignore-ondemand <0|1> Default setting is 1. Incidentally this is what buildroot does using a wrapper, when using an external toolchain. Attach with cuda-gdb, and see what’s going on $ cuda-gdb myCudaApplication PID Program received signal SIGTRAP, Trace/breakpoint trap. Coding is fun, so databases must be fun too. To compile with debugging flags, for use with gdb. The server is usually an executable running on the same machine, but it can run anywhere in the network too on a remote machine. Issue whatever gdb commands you choose. GDB: How do I set current source file for list and break commands People who start using GDB after GUI debuggers often ask this question in the title. The set auto-solib-add command specifies whether GDB should automatically load symbols when it detects that a shared library has been loaded. On the host system, run gdb gdb /host/path/to/program (gdb) target remote :1234 is the name of the remote system or it's IP address. Example: Simple Hello world project, additional lib freetype and jpeg (they should exists host-sysroot), linked to binary. I've tried to use the GDB 7. In this case the GNU/Linux system is the host, and the MIPS ELF system is the target. /configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. Remote Debug via GDB/gdbserver. If that is the case then you have to tell both the build system and the Urho3D library (more specifically the Engine class) where the resource paths are. In the above example, set sysroot from MPSS installation in. There may be occasions when you need to know something about the protocol--for example, if there is only one serial port to your target machine, you might want your program to do something special if it recognizes a packet meant for GDB. For example (assuming sh/bash/ksh): CC=gcc. /configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. Start GDB server a. Add the cross-compiler. See 'info gdb' for the detail. It is assumed that the reader is already familiar with Unix, and has been exposed a bit to the Intel register and instruction set. how to save "set solib-search-path" There are a bunch of interesting examples of various complexity around. GDB GDB is the standard debugger for Linux and Unix-like operating systems. Debugging the linux kernel using gdb. Remove GDB from Sandbox. The graphical user interface (GUI) domainates the current operating environments for personal computing. Produced file is equivalent to a kernel produced core file as if the process crashed (and if "ulimit -c" were used to set up an appropriate core dump limit). GDB can work with this debugging information. I mean, the set up seems robust enough that it won't cause problems in the long run, but what bothers me is the fact that I'm using technologies that are alien to me. gpx eXchange is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and Web services on the Internet. The debugger still follows the parent. This kind of command works just as it would within C or C++; for example, you can look at a particular element in an array with print myarray[5] or a field in a structure with print struct.
