CMake Linker Error with CppUnit OS X 10.10

I'm having an issue with my CMake environment. My team uses CppUnit, however our test build has been failing ever since upgrading to OS X 10.10 (Yosemite) This build works on Linux machines and OS X Mavericks. We are at a loss as to why it is not working.

Our CMakeLists.txt can be found here: https://gist.github.com/VikomMedia/802fb41a411dd2f7358e

The result is identical with -stdlib=libc++ and -stdlib=libstdc++

Thank you very much.

Solution

  • We were able to solve the issue by changing the compiler to G++ on OS X 10.10 machines. clang++ was not working, the reason is unknown at this time.
