I'm not sure what's going on. On my new M$ MacBook, after installing Macports ,I installed gcc14 in order to get the Fortran compiler, gfortran
I used: sudo port install gcc14 and selected it using; sudo port select --set gcc mp-gcc14 which showed as selected: sudo port select --list gcc Available versions for gcc: mp-gcc14 (active) none and ...$ which gcc /opt/local/bin/gcc ...$ gcc --version Apple clang version 16.0.0 (clang-1600.0.26.4) Target: arm64-apple-darwin24.1.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin gfortran --version does return the gcc14 version. Why is the gcc --version for gcc still showing the Apple clang version? DN David C Nicholls Research School of Astronomy & Astrophysics Australian National University
