#100 Can't link static library freebsd 10
Linking check-0.9.14's static library libcheck.a on Freebsd 10 gives undefined references as seen below...

However linking the shared library does not produce undefined references. The linking problem does not affect Mac OSX 10.10 and I have yet to try and see if the issue affects linux.
I do not know much about static libraries, so I started looking up how they work and how this might be affecting your project.
Are you including other libraries into your project, perhaps the realtime (rt) or math (m) libraries? According to this description of linker order issues with static libraries:
http://stackoverflow.com/questions/45135/linker-order-gcc
perhaps your project needs to include the rt and math libraries (if it already does) after it lists libcheck.a. Take a look at that page and see if any of the answers are helpful. If they are, maybe reply back and let me know what you found.
