Hi, I want to build gcc-13 on my M1 MacBook Pro. Following official document , I download source code using git, configure and make. For configure, I refer to the way of Homebrew configure gcc-12 on link . Specifically is ../configure \ --prefix=/Users/xubaoyu/gcc/build \ --disable-nls \ --enable-checking=release \ --with-gcc-major-version-only \ --enable-languages=c,c++ \ --program-suffix=-13 \ --with-system-zlib \ --build=aarch64-apple-darwin22 \ --with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX13.sdk And simply make -j 10. Then error occurs: *** Configuration aarch64-apple-darwin22 not supported make[2]: *** [configure-stage1-gcc] Error 1 make[1]: *** [stage1-bubble] Error 2 make: *** [all] Error 2 I think I use the wrong value on build parameter, so I check gcc12 by gcc-12 -v: Using built-in specs.
