Accessing gdb console in Qt-Creator

gdbqt-creator

Is there an access to the gdb console from Qt-Creator? For examining frames, dumping to file, etc. Seems a trivial feature but I couldn't find a clear reference to weather it exists or not.

I am using Qt-Creator 2.0.1 under Ubuntu 9.10

Window > Views > Debugger Log. You can type commands in the left pane and send a line to gdb using ctrl+enter. More info here: http://qt-project.org/doc/qtcreator-3.2/creator-debug-mode.html#directly-interacting-with-native-debuggers

For examining frames using the "normal" views, especially the Watchers part of the Locals and Watchers view should probably be the better approach.

This also works:

LD_PRELOAD=/lib/libpthread.so.0 gdb --args ./app

C++ – Remote GDB debugging

So that GDB on your host (the machine you develop and compile on, so where you have Qt Creator) you have to give it access to the "symbol file".

I usually don't use Qt Creator, but GDB and gdbserver directly for cross-compiled programs remote-debugging. You could maybe give this a try to be sure that this works for you and maybe then find the missing option in Qt Creator (or maybe this will help you find what is missing).

On the target machine run:

gdbserver :5000 yourprogram

On the host machine, run gdb and then load the symbol file:

(gdb) symbol-file yourprogram

On GDB on the host machine, you then have to connect to connect GDB to the remote gdbserver:

(gdb) target remote target_ip_address:5000

From then you can use GDB on the host controlling the program on the target.

I hope this helps!
