It may also be necessary to provide these system libraries from the core-host so that dbx can understand the runtime linker data structures and the threads data structures. There are some sleep() calls in the gdb_example2, so that you have time to kill it with the SIGSEGV signal. news
thread apply [thread-id-list | all [-ascending]] commandThe thread apply command allows you to apply the named command to one or more threads. set libthread-db-search-path [path]If this variable is set, path is a colon-separated list of directories gdb will use to search for libthread_db. Updated 3 months ago. What is the common, normally open, normally closed?
This means that you as the package owner are responsible to modify the debian package configurations, so that the dpkg-buildpackage tool will produce the additional dbg-package. The user libraries and system libraries can change in patches as well as major Solaris operating environment upgrades, so this problem can even occur on the same host, if, for example, USB cable to connect the device with the Linux PC Internet access both for the tablet and for the Linux PC USB networking (or WLAN) set up between the Linux PC It is recommended that first osso-xterm and then ssh are installed in the device before continuing.
N.B. How does Gandalf end up on the roof of Isengard? The IP address is an example, and your device IP address can be different. [sbox-armel: ~/src/testing/gdb_example] > ssh [email protected] [email protected]'s password: .......... The system libraries that you might need are: For the runtime linker: /usr/lib/ld.so.1 /usr/lib/librtld_db.so.1 /usr/lib/64/ld.so.1 /usr/lib/64/librtld_db.so.1 For the threads library, depending on which implementation of libthread you are using: /usr/lib/libthread_db.so.1 /usr/lib/64/libthread_db.so.1
This section covers the two basic debugging tools available in the maemo environment, and shows how to use them. If gdb detects the program is multi-threaded, it augments the usual message about stopping at a breakpoint with the ID and name of the thread that hit the breakpoint. If the dbg packages for various libraries were not installed, it would mean that the backtrace information coming from the non-debug version of the library could not be trusted. Set the breakpoint (br) to function example_3 (gdb) br example_3 Breakpoint 1 at 0x80483e9: file gdb_example.c, line 48.
and compile it like this: [sbox-x86: ~/src/hello-world-app-2.1] > export DEB_BUILD_OPTIONS=debug,\ nostrip [sbox-x86: ~/src/hello-world-app-2.1] > ./autogen.sh ... That is, in expanded qualified form, the same as ‘1.1 1.2 1.3 4.5 6.7 6.8 6.9 7.1’. For additional gdb documentation, take a look at the maemo tools documentation for gdb. 22.214.171.124 Setting up Environment Both the Internet Tablet device, described in section Setting up USB Networking 3.5, If you want to be able to resolve symbols also for the library during debugging, you need to install libc6-dbg package in the device.
For example, assuming that the root partition of the core-host has been exported over NFS and can be accessed via /net/core-host/ on the dbx-host machine, you would use the following commands Keep in mind that generally the Scratchbox tools override the target tools. 126.96.36.199.5 Debugging UI Applications in Scratchbox X86 Many maemo applications use the graphical UI, and debugging these applications differs N.B. You signed in with another tab or window.
In this material, the native-gdb (i.e. navigate to this website N.B. When debugging threads in an application, gdb needs to be linked against the same thread library that the application is using. This section covers creating a Debian debug package from the maemo/Scratchbox point of view.
If none of libthread_db libraries initialize successfully, gdb will issue a warning and thread debugging will be disabled. the ones the application is using) from the device to the Scratchbox. Are keywords in resolv.conf case sensitive? http://bovbjerg.net/warning-cannot/warning-cannot.php If this initialization fails (which could happen because of a version mismatch between libthread_db and libpthread), gdb will unload libthread_db, and continue with the next directory.
The backtrace tells what functions were called before the breakpoint was reached at hello_world_dialog_show(). For gdb to find old style debug symbol files (installed directly into /usr/lib/debug/) you need to use LD_LIBRARY_PATH or load them manually in gdb. These were required with the old way to use dh_strip.
Unplumbing the ipv6 loopback got me farther. Keyboard Shortcuts File u :up to issue m :publish + mail comments M :edit review message j / k :jump to file after / before current file J / K :jump This way, you will not accidentally get programs from the wrong repository to the device. Now the plug-in can be debugged normally with gdb.
Try something simple, like using the list command to see where the execution of the application is going. For bug reporting instructions, please see: http://www.gnu.org/software/gdb/bugs/... Valgrind also tells the lines in the code where these allocations that are not freed are performed. click site The one used can be checked with: [sbox-x86: ~] > which gdb /targets/links/arch_tools/bin/gdb If only using the command gdb, then the gdb used is the one provided by Scratchbox.
Start the Xephyr server outside the Scratchbox: Linux-PC$ Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac -extension Composite & Start the Application Framework from inside the Scratchbox X86 target: [sbox-x86: ~/src/maemopad/maemopad-2.1] Type "show warranty" for details. You should see a list of functions that have been called, similar to the following: (gdb) bt #0 hildon_help_show (osso=0x80bda40, help_id=0x804cb08 "Example_MaemoPad_Content", flags=1) at osso-helplib.c:636 #1 0x0804bfb0 in callback_help (action=0x80bda40, data=0x1) vi), but the following command given from the osso-xterm is also valid: echo "deb http://repository.maemo.org/ diablo free non-free" >> /etc/apt/sources.list Important: it is not recommended to perform device software updates from

If the Scratchbox environment is set up correctly as explained above, these steps should be easy to follow to perform UI debugging with maemopad application.
The gdb needs to be installed in the Internet Tablet device. If you need to debug threads in the application, you need to use the native gdb linked against the same thread library that your application is using. Does the Rothschild family own most central banks? The number 22961 is just an example. # smallest PID value is maemo-invoker which had requested maemo-launcher to start hildon-desktop. # [sbox-x86: ~/ ] > native-gdb maemo-launcher ...
Specify the threads that you want affected using the thread ID list syntax (see thread ID lists), or specify all to apply to all threads. Debugging commands show program information from the perspective of the current thread. If the package has any function(s) that have the noreturn GCC attribute, you need to make sure that the object(s) containing those are compiled with -fno-omit-frame-pointer (or remove the noreturn attribute). valgrind - Debugger and profiler.
The tools are: gdb - The Gnu Project Debugger.
