I have program that depends on library that is linked to libboost 1.67, which installed in the system. When I launch it, I have an error that libboost_system.so.1.58 does not exist. LD_PRELOAD and LD_LIBRARY_PATH are unset.

lddtree execution doesn't show this library as dependency but ldd does.

How can I trace from where the library is required?

If on a GNU system, try running your application with:

LD_DEBUG=libs your-application

See LD_DEBUG=help for more options or man ld.so.

  • when I try LD_DEBUG=libs python3.6 on tcsh I get LD_DEBUG command not found. What is the tcsh alternative ? – gansub May 6 at 13:11

    @gansub prefix the command with env in tcsh – Stéphane Chazelas May 6 at 15:20

If the program is loading libboost_system manually using dlopen(), you might be able to find where it is doing that using ltrace to see if it is calling dlopen(), and maybe gdb to set a breakpoint on calls to dlopen() and then generating a stack backtrace. (See also latrace.)
