Question

Say you have 2 share libraries, lib1.so and lib2.so, that both have libcommon.a statically linked into them. Would the compiler complain about ambiguous symbol reference if you were to dynamically link both lib1.so and lib2.so? Or would be the compiler be smart enough to know libcommon symbols are shared between lib1 and lib2 and allow you to dynamically link against both?

Answer 1

The static library would be used to resolve the links internally but the external linkage would not be propagated to the shared library interface, so there would be no conflict. Each shared library would include its own copy of the static library code.
