"Undefined Reference" Error From ld

Question

Hi there!

This isn't as naive as the title may lead you to think.

I receive an "Undefined Reference" Error from the linker/ld for a couple of function symbols in third party shared library, that I'm trying to link with my executable.

The strange part is, that library itself is supposed to contain the definition for the offending symbols in question.

The stranger part is that there are several executables in my project, with some facing this problem and some not.

Have I messed up my gcc/ld flags or is it something else?

Answer 1

Impossible to say from your description, which contains approximately zero useful information. One possibility is that you are not including the correct header file in some source files.
