Build errors from #include files

I am using CLion on a Mac and trying to build a C++ project that I know builds cleanly on other machines. When I build it I get a lot of errors related to very low level core files. I have tried using both clang and gcc and both produce the same errors. I have also tried uninstalling and reinstalling CLion. Any ideas what could be causing the following errors?
