MacOS Sonoma cmake%gcc@13.2.0 Patch

Release date: 27 December 2023

Some modifications to the MacOSX sdk to get cmake to compile with gcc

Tested using M3 Pro CPU

Instructions:

Clone the repository and modify the files on your system. After all the files are updated with the changes, get the number of physical cores in your system with the following:

sysctl -n hw.physicalcpu

This will return an integer similar to nproc in linux. After getting the number of cores in your system:

cd macos_sonoma_gcc_patch
sh install_spack.sh

After this runs successfully,

source ~/.zshrc
spacktivate

Now, we will build the latest gcc compiler. At the time of writing, the latest compiler is gcc@13.2.0. We can get the current latest compiler by using:

spack info gcc

Install gcc with the following, replacing 13.2.0 with the latest version returned from spack info, and 22 with two times the integer returned from sysctl -n hw.physicalcpu:

spack add gcc@13.2.0
spack concretize
spack install -v -j22

Verify the compiler is working correctly with:

which gcc
gcc --version

After verifying, install cmake with the following, using the same values from above:

spack add cmake%gcc@13.2.0
spack concretize
spack install -v -j22

...and verify:

which cmake
cmake --version

Results:

spack.yaml

spack install:

Modifications:

My solution basically just:

#define ATS_UNAVAILABLE (FALSE)

...and for each error during the build:

#if ATS_UNAVAILABLE
...
#endif

I understand this probably isn't the best solution--it would be better to define ATS_UNAVAILABLE in one file and reference it; however, I am not familiar with the SDK and this works for me.
