How to avoid dependee library symbols conflict?

Question

I have a Fortran executable that statically links against a specific version of hdf5. The executable makes use of a C++ library foo that is statically linked against a different version of hdf5.

The executable refuses to link because of conflict in symbols. Is there a way to avoid this issue without making the C++ library foo dynamic?

Welcome, I suggest taking the welcome [tour]. Can't you just link everything with a single version of the library? — Vladimir F Героям слава, Dec 02 '22 at 13:05
Many versions of the executable will be produced. The hdf5 version of Fortran needs to change for each version. This means, I will have to recompile the C++ library foo with each version, noting that the executable doesn't make use of the hdf5 part of the C++ library foo. — Striger, Dec 02 '22 at 18:40

This can work, but you must hide the fact that foo contains a version of the hdf5 library by hiding all of hdf5 symbols. Doing so will avoid symbol conflicts.

Thanks for the reply. But this is specific to g++? Because I am using VC++. – Striger Dec 06 '22 at 14:41
