Sorry @GowthamKudupudi this is a not supported use case.

On MacOS, the compiler warppers are used to intercept the compiler calls. The best thing I can recommend is to write a simple makefile, which uses the CC environment variable. And you can call Bear as CC=clang bear -- make.

print_mpz: print_mpz.c
        $(CC) -o $@ $< -lgmp -ggdb -O3
