--- Comment #34 from Matt Thompson <matthew.thompson at nasa dot gov> --- Iain, Apologies. I forgot about this. Seeing as I'm now using GNU 10.2.0 on my Macbook...I guess it's working. I currently do: ../gcc-10.2.0/configure --prefix=$HOME/installed/Core/gcc-gfortran/10.2.0 --enable-languages=c,c++,fortran --with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk |& tee configure.log when I configure it which is much as you suggested. My guess is I worked with my admins nuking and restoring XCode until we got it right (or something, government laptops are fun, no sudo, lots of restrictions...). Thanks for your help, and I can't wait for 10.3 or 11.0 or whatever is next! N Note: I'm still on an Intel Mac, so I won't need to bother "Iain Sandoe, master of M1 GNU" about that for a while. :D
