nm src/.libs/liblcms2.2.dylib 

Shows the entries:

00035b10 t _cmsIT8LoadFromFile

But small t, so not public.


So I changed hidden in "-fvisibility=hidden" in configure file to xxx, and the 

checking whether C compiler accepts -fvisibility=xxx… no

Happens and the visibility flag is not used.

Than everything works fine and builds.
Can you make sure the flag is not used when building shared library?

Sincerely
Christian
