Thanks! I tried this and get the warning `g++-12: warning: /usr/local/opt/libomp/lib/libomp.dylib: linker input file unused because linking not done`, but so far everything is compiling.

Sorry - the linking caused a build error on the last step.

I tried compiling using Clang instead of GCC, and also had a failure. ``` [287/402] Building CXX object Macaulay2/e/CMakeFiles/M2-engine.dir/eigen.cpp.o FAILED: Macaulay2/e/CMakeFiles/M2-engine.dir/eigen.cpp.o /usr/local/bin/ccache /usr/local/opt/llvm/bin/clang++ -DNDEBUG -DOM_NDEBUG -DSING_NDEBUG -I/Users/trevorkarn/Applications/M2/M2/M2/Macaulay2/e -I/Users/trevorkarn/Applications/M2/M2/M2/Macaulay2/d -I/Users/trevorkarn/Applications/M2/M2/M2/Macaulay2/c -I/Users/trevorkarn/Applications/M2/M2/M2/BUILD/build/Macaulay2/d...

Thanks, Jay. That helped a bit. I was having trouble with polymake and your suggestion fixed that problem. I tried to uninstall/reinstall `libffi` using homebrew. Upon reinstalling I see the...

Thanks Mahrud, I tried: ``` trevorkarn@MacBook-Air-196 build % cmake -U"*FFI*" CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working...

I realized maybe I should be in the same directory as CMakeLists.txt, and II get ``` trevorkarn@MacBook-Air-196 build % cd ../.. trevorkarn@MacBook-Air-196 M2 % cmake -U"*FFI*" CMake Warning: No source...

I'm so sorry - what do you mean the "sure as the end"? By `ls`-ing I see that `CMakeCache.txt` is indeed in `M2/BUILD/build` while `CMakeLists.txt` is in `M2`. From `M2/BUILD/build`...

Ah thanks! Now the problem with ffi seems to be fixed, but there is still the unknown argument `-MD`. ``` trevorkarn@MacBook-Air-196 build % ninja M2-binary M2-core [1/203] Building CXX object...
