With default setting of Make file I was getting the following error:
clang: error: the clang compiler does not support ‘-march=native’
Then someone from the community also experience an issue with this and solution was provided by changing -march=native to -mcpu=apple-a14, but that landed me on another issue which is omp.h not found. After researching for quite a long time I found out this error is caused of clang incompatibility on apple-m1.
