Qt Creator 2.7.1 and Qt 4.8.4 Cannot Remotely Debug Library

Question

Using Qt Creator 2.7.1 and Qt 4.8.4, I made a Qt library and a simple Qt app that dynamically links against this library. I am attempting to remotely deploy and debug my App and step into my library functions when I call them. I can successfully set breakpoints and debug remotely, but I cannot step into my library functions using the debugger ( gdb ). When I first remotely launch my application using QtCreator in debug mode, I am met with the following warnings:

Could not load shared library symbols for 7 libraries, e.g. libcustom-stuff.so.1.
Use the "info sharedlibrary" command to see the complete listing.
Do you need "set solib-search-path" or "set sysroot"?

My debugger is setup using QtCreator as shown in these images ( Note that I have switched both the 'Target Path' and 'Path' in image #3 but it did not help:

My 'Kit' is setup as follows:

In the 'Debugger Log' within Qt Creator I entered the 'Command':

info sharedlibrary

To which I got the response:

>~"From        To          Syms Read   Shared Object Library\n"
>~"0x400007e0  0x40011bf0  Yes         /home/user/proj/output/buildroot/host/usr/arm-buildroot-linux-gnueabi/sysroot/lib/ld-linux.so.3\n"

I also ensured that both the library and app were built with:

CONFIG+=declarative_debug

In the 'Compile Output' pane for both the library and app I see the '-g' flag.

They both reside in the same directory on the file system so what is going on! Howcome I can debug and set breakpoints in the App, but not step into the Library calls? Any ideas are greatly appreciated.

UPDATE:

As per the suggestion by kikeenrique, I tried to load the debugging symbols from my Ubuntu Host ( not the ARM target ):

It seems GDB could load the symbols at least..

Answer 1

Are you using a different architecture for your remote app?

If they are different you would need to use the same gdb server and client arch.

Try setting LD_LIBRARY_PATH in your project->build & Run->build environment with the path to your library.
