Your recollection is correct. On Linux (and maybe some other unices) the
shm_open() and shm_unlink() is provided by librt. On Mac OS, a separate
library is not needed. I hacked the util/CMakeLists.txt to test it out and I
got it to build. I ran x01c and the wxWidgets driver appeared to work
correctly. The following section in util/CMakeLists.txt needs to be modified
to exclude Mac OS X (Darwin)
if(UNIX)
set(RT_LIB rt)
endif(UNIX)
I would look into fixing, but I am leaving in a few minutes and will be away
from my development machine for the next few days.
