Can I get a report of ALL the libraries linked when building my C++ executable (gcc)? (including statically linked)

I had similar problem and found solution: add -Wl,--verbose option when linking. It will switch linker to verbose mode:

gcc -o test main.o -ltest -L. -Wl,--verbose

Here is example output:

GNU ld (GNU Binutils) 2.23.52.20130604
  Supported emulations:
   i386pep
   i386pe
using internal linker script:

Update: You can also use -Wl,--trace option instead of -Wl,--verbose. It will also give you list of libraries, but is less verbose.

Update 2: -Wl,--trace does not display libraries included indirectly. Example: you link with libA, and libA was linked with libB. If you want to see that libB is needed too, you must use -Wl,--verbose.

For direct dependencies;

ldd <app>

Indirect/All dependencies;

ldd -r <app>

As far as I know, not much information about static libraries is preserved when linking (since the linker just sees that library as a collection of *.o objects anyway).

If you find the make command that links the final executable and add a -v flag, g++ will show you exactly how it calls the ld command. This should include all necessary static libraries, including libraries used by other libraries, or otherwise the link step would fail. But it might also include extra libraries that aren't actually used.

Another possibly useful thing is that, at least on Linux, objects and executables usually store names of the source code files from which they were created. (Filename only, no path.) Try

objdump -t executable | grep '*ABS*'
