Compilation possible on macOS with ARM64 architecture?

[yonghoonlee]

I tried to compile using the conda-forge compilers toolchain, but it didn't work.
What I tried was:

conda create -y --name cactus
conda activate cactus
conda install -c conda-forge compilers cmake
mkdir -p build
cd build
cmake ..
make

When I run cmake, I got the following output:

cmake ..

However, when I try to make, I get following error message:

make          
[  1%] Building Fortran object CMakeFiles/cactus.dir/src/mod/airfoil.f90.o
arm64-apple-darwin20.0.0-gfortran: fatal error: no input files
compilation terminated.
/bin/sh: -O2: command not found
make[2]: *** [CMakeFiles/cactus.dir/src/mod/airfoil.f90.o] Error 127
make[1]: *** [CMakeFiles/cactus.dir/all] Error 2
make: *** [all] Error 2

When I checked the folder CMakeFiles/cactus.dir/src/mod/, there was no "airfoil.f90.o" file created there.
However, I was able to still find the input file (../src/mod/airfoil.f90), and I also checked the content of the source code.

How can I resolve this problem? Thank you.

No solution here, but I also encounter this using the conda-forge compilers toolchain and x86_64 Python. So it seems this is a general problem of the CMakeLists.txt on Mac, not specific to ARM64.
