Actually why not looking for /usr/bin/clang instead of /usr/bin/gcc? That would make the code more explicit.

Also maybe the function findGccOnMacos() could be renamed findCompilerOnMacos()

And returning a second boolean argument (within a pair<string, bool>) to tell whether it’s GCC or Clang

The implementation of the boolean unfortunately does not work neither on my system nor on the MacRunner. If /usr/local/bin/gcc-13 is found, it still uses Clang. However, if I temporarily mv /usr/local/bin/gcc-13 /usr/local/bin/gcc-13.bak, then all works (under Clang). I had the same issue and it was due to the boolean, however, I have no clue why. To replicate on the macOS runner: I compiled it under /Users/willi/dynare/unstable and simply ran dynare example1 use_dll from the example folders:
