> 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.

That is the exact area which my recent fix for rt changes. The new logic now excludes the possibility of ever explicitly linking with rt on Mac OS X so regardless of further changes with other Unices, Mac OS X should be excluded and you should be able to build and run wxwidgets without issues on that platform. This build system logic does need testing on as many Linux platforms as possible since I have dropped explicit linking to rt in all cases now. But if it turns out any of those tests reveal explicit linking is required on any Linux platform that is just a one-line change to the CMake logic which would not affect the Mac OS X case.
