We've covered how to build a shared library, how to link with it, and how to resolve the most common loader issues with shared libraries-as well as the positives and negatives Indeed, the latter was true for the GSL and the HDF5 libraries, and symlinking /usr/lib/libgsl.a -> /usr/lib/libgsl.dll.a /usr/lib/libgslcblas.a -> /usr/lib/libgslcblas.dll.a /usr/lib/libhdf5.a -> /usr/lib/libhdf5.dll.a solved the problem. Without that it is just guesswork what might be wrong. –Anthon Oct 13 '14 at 17:47 add a comment| Your Answer draft saved draft discarded Sign up or log in winterhunter Linux - Software 7 10-24-2005 05:37 AM Linking Libraries, Dependencies Killbot_5000 Linux - Software 4 09-28-2004 09:59 AM Problem with linking libraries using gcc shortyzms Linux - Software 1 03-29-2004
