Eric: To the best of my knowledge every release of GCC after 4.6 (when we fixed powerpc-darwin9) should bootstrap correctly on all Darwin archs supported by upstream (i.e. not including Arm64 yet). There can be (sometimes extended) periods where trunk (or even branches) are broken for some/all Darwin - since there's not many folks fixing it - but x86_64 is not currently broken anywhere AFAIK. ===== Bringing up Ada on a new plafform version - the devil is in the details: AFAIK you have a copy of my gcc-7.5-darwin19 toolchain? This _is_ sufficient to build a new bootstrap compiler on Darwin20 including Ada. the following should work - for 11.5, 12.4, 13.3, 14.2 and trunk .. $ uname -v Darwin Kernel Version 20.6.0: Thu Jul 6 22:12:47 PDT 2023; root:xnu-7195.141.49.702.12~1/RELEASE_X86_64 1. start a shell with just the normal OS PATH 2. you need to have texinfo-6.7 or similar ahead of the OS version (which is not new enough to support trunk). 3. My PATH looks like: PATH=/opt/iains/x86_64-apple-darwin20/gcc-build-tools/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/iains/x86_64-apple-darwin19/gcc-7-5-toolchain/bin The first entry has texinfo-6.7 and dejagnu. 4. $ gnatmake --version GNATMAKE 7.5.0 there is no other GCC or gnatmake in my PATH - but remember that Xcode will claim 'gcc/g++' is 'clang/++'. 5. configure: /src-local/gcc-master/configure --prefix=/opt/iains/x86_64-apple-darwin20/gcc-15-0-0 --build=x86_64-apple-darwin20 --with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX11.sdk --disable-libstdcxx-pch --enable-languages=all CC=x86_64-apple-darwin19-gcc CXX=x86_64-apple-darwin19-g++ NOTE1: we _have_ to put CC and CXX because otherwise we run into problems because of the claiming of gcc/g++ as above. NOTE2: x86_64-apple-darwin19-gcc <<- this MUST match the version of gnatmake (there's only one in the PATH so that should be OK) NOTE3: the --disable-libstdcxx-pch should be irrelevant NOTE4: There might _still_ be places in the Ada build where "gnatmake" is used literally - instead of GNATMAKE_FOR_XXXX so it is very important to make sure that the NOTE2 is observed. 6. make -jN .. 7. $ ./gcc/xgcc --version xgcc (GCC) 15.0.0 20240721 (experimental) [master revision r15-2183-g58b78cf068b3] (Sunday AM trunk) ==== Works For Me as I have repeatedly said - you need to examine carefully what you are doing differently - if there's a real bug I'd like to fix it - but I cannot see one at present. ==== 11.5 might be a good one to build since that also gives you a D compiler to bootstrap D on gcc-12+ I just built the darwin branch released over the weekend... configure: /src-local/gcc-git-11/configure --prefix=/opt/iains/x86_64-apple-darwin20/gcc-11-5-darwin --build=x86_64-apple-darwin20 --with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX11.sdk --disable-libstdcxx-pch --enable-languages=all CC=x86_64-apple-darwin19-gcc CXX=x86_64-apple-darwin19-g++ $ ./gcc/xgcc --version xgcc (GCC) 11.5.0 --------
