Build failure on Mac

[rckirby]

Trying to pip install in a recently updated Firedrake install, I get an error message, with the critical failure being:

clang: error: the clang compiler does not support '-march=native'

Is there a way to work around this? I'd really like to get the performance that TinyASM offers on my patch problems!

Remove -march=native (only makes sense on x86) from

TinyASM/CMakeLists.txt

Line 17 in 015a89a

set(CMAKE_CXX_FLAGS "-O3 -march=native -DLINUX -DNDEBUG")

Thanks, that got it to work. (Oddly, I didn't need to delete -DLINUX). Would it be possible to update the configuration to sniff out non-x86 (e.g. Mac Silicon) and set the flags accordingly?

probably yes, but cmake is a closed book to me. You need to find a friendly C++ developer :).
