Hi Mark,

Yes may be,  I'm afraid I do...
This is the libRTI-->libFedTime-->libRTI circular reference hitting again.

See the bunch of reference here:
https://savannah.nongnu.org/bugs/?30003

May be the default behavior of gcc on the Mac is to set visibilty to
hidden, does it?
see: http://gcc.gnu.org/wiki/Visibility

I am trying to reproduce the issue on Linux using gcc -fvisibility=hidden.
On your side may be you can try to add

-fvisibility=default into CFLAGS (or modify main CMakeLists.txt in the
GCC specific area).

Which version of CERTI are you trying to build?
