How to make the debugged app find shared libraries when invoked in gdb inside Eclipse CDT?

Question

I'm trying to debug Firefox trunk inside Eclipse CDT on Linux x86_64 (Ubuntu Karmic).

I have done the following:

• I have made a path mapping from / to / per DevMo in the Source pane of the project-level Run/Debug config.
• I have set /opt/Projects/obj-debug/dist/bin/firefox-bin as the C++ app in the Main pane. (My Firefox obj dir is /opt/Projects/obj-debug)
• I have set the working dir to /opt/Projects/obj-debug/dist/bin in the Arguments pane
• I have set the arguments to -no-remote -P dev in the Arguments pane
• In the Environment pane, I have set the environment to append the following based on what run-mozilla.sh does:
  • ADDON_PATH : /opt/Projects/obj-debug/dist/bin
  • DISPLAY : :0.0
  • DYLD_LIBRARY_PATH : /opt/Projects/obj-debug/dist/bin:/opt/Projects/obj-debug/dist/bin
  • LD_LIBRARY_PATH : /opt/Projects/obj-debug/dist/bin:/opt/Projects/obj-debug/dist/bin/plugins:/opt/Projects/obj-debug/dist/bin
  • LIBPATH : /opt/Projects/obj-debug/dist/bin:/opt/Projects/obj-debug/dist/bin
  • LIBRARY_PATH : /opt/Projects/obj-debug/dist/bin:/opt/Projects/obj-debug/dist/bin/components:/opt/Projects/obj-debug/dist/bin
  • MOZILLA_FIVE_HOME : /opt/Projects/obj-debug/dist/bin
  • NO_EM_RESTART : 1
  • NO_REMOTE : 1
  • SHLIB_PATH : /opt/Projects/obj-debug/dist/bin:/opt/Projects/obj-debug/dist/bin
• In the Debugger pane I have
  • Chosen gdb Debugger
  • I have set the gdb executable to gdb and .gdbinit to /home/hsivonen/.gdbinit

The above is enough to launch Firefox successfully using Run. However, when launching using Debug, I get this one line in the console: /opt/Projects/obj-debug/dist/bin/firefox-bin: error while loading shared libraries: libmozalloc.so: cannot open shared object file: No such file or directory

I have additionally tried to put the relevant paths in the shared library subpane of the Debugger pane and I've tried to put set solib-search-path /opt/Projects/obj-debug/dist/bin/components:/opt/Projects/obj-debug/dist/bin/plugins:/opt/Projects/obj-debug/dist/bin in my .gdbinit.

No luck.

What should I do to make the shared libraries found when the app is debugged?
