How do I get a debugged application to find shared libraries when called in gdb inside Eclipse CDT?

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

I did the following:

  • I created a path mapping from / to / to DevMo in the Source area of ​​the Project / Level Run / Debug configuration.
  • I have installed / opt / Projects / obj -debug / dist / bin / firefox-bin as a C ++ application in the main area. (My Firefox obj dir is / opt / Projects / obj-debug)
  • I have set the working directory / opt / Projects / obj -debug / dist / bin in the Arguments panel
  • I have set the arguments to -no-remote -P dev in the Arguments panel
  • In the Environment area, I set up an environment to add 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 panel I have
    • Selected debugger gdb
    • I have installed gdb executable in gdb and .gdbinit in /home/hsivonen/.gdbinit

The above is sufficient to successfully launch Firefox using Run. However, when running 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 also tried to put the appropriate paths in the shared library set solib-search-path /opt/Projects/obj-debug/dist/bin/components:/opt/Projects/obj-debug/dist/bin/plugins:/opt/Projects/obj-debug/dist/bin

subview of the Debugger panel and I tried to install in my .gdbinit.

Bad luck.

What can I do to make shared libraries discovered when I debug my application?

I often successfully use the CDT debugger this way:



  • from terminal, set up a working environment for the binary you want to debug (export LD_LIBRARY_PATH, etc.)
  • from terminal of the same , start eclipse (eclipse inherits environment)
  • from eclipse, select "Makefile Project With Existing Code" and import your folder
  • in the left pane, select your binary and right click: Debug as -> C / C ++ Application.
