module compilation failed

[AMzaheri]

Hello,

I have encountered a compilation error when running a simple example on a Macbook. The error is :

clang: error: the clang compiler does not support '-march=native' FAILED compiler invocation:gcc -O3 -g -fPIC -Wall -std=c99 -march=native -Wno-unused-result -Wno-unused-variable -Wno-unused-but-set-variable -ffast-math -shared /var/folders/6r/g59xwcqd73nft3q3n_00hrqr0000gq/T/devito-jitcache-uid503/8b237ac1f1a4370f307afea8531adbdba661d48e.c -lm -o /var/folders/6r/g59xwcqd73nft3q3n_00hrqr0000gq/T/devito-jitcache-uid503/8b237ac1f1a4370f307afea8531adbdba661d48e.dylib

It looks like you have devito configured for gcc (gnu) but that your gcc links to clang instead.

You will need to either configure devito with clang (DEVITO_ARCH=osx) or install a proper gcc compiler. You can for example install it with brew brew install gcc.
