How to debug a program wrapped in a libtool script?

Question

I have a project involving

• shared libraries ie: mylib.so
• (test) program using these shared libraries ie: test_mylib

Answer 1

This is problem I ran into a couples of days ago and there is no generic answer on SO yet. Only special cases. Here is the answer I found on this page: http://www.gnu.org/software/libtool/manual/html_node/Debugging-executables.html

Until the program is installed, the system does not know where to look for the shared objects. They usually lies in .libs sub-directory of their source folder.

Libtool generates a convenience script to allow debugging before the actual installation is done (who wants to install buggy software before, debug it after?)

Fortunately, the generated script provides a helper for this:

libtool --mode=execute gdb test_mylib
