Hello.
I was trying to check what is required to build gollvm on Alpine linux (it has musl instead of glibc). Look like recently revealed <https://gitlab.alpinelinux.org/alpine/aports/-/issues/12060>set of minimal requirements allowed to build the configuration file (for Ninja). heading to check whether Ninja would compile. I wasn't able to find a pre-compiled Clang 11, for Alpine - but Clang 10 was available, which was pre-compiled against musl (C++ standard library has to rely on musl, instead of glibc - as I suppose). Maybe I would recompile Clang 11, for Alpine distro - but not today. Must admit that CMake worked much faster, compared to Ubuntu. Comments would be much appreciated. So, I am stuck: [1/1084] Building sysinfo.o FAILED: tools/gollvm/libgo/sysinfo.o cd /home/oceanfish81/workarea/build_release/tools/gollvm/libgo && /usr/bin/clang -g3 -c -fno-eliminate-unused-debug-types /home/oceanfish81/workarea/llvm-project/llvm/tools/gollvm/gofrontend/libgo/sysinfo.c -o /home/oceanfish81/workarea/build_release/tools/gollvm/libgo/sysinfo.o -D_GNU_SOURCE -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/home/oceanfish81/workarea/build_release/tools/gollvm/libgo -I/home/oceanfish81/workarea/build_release/tools/gollvm/libgo/runtime /home/oceanfish81/workarea/llvm-project/llvm/tools/gollvm/gofrontend/libgo/sysinfo.c:462:1: error: tentative definition has type 'struct sigstack' that is never completed SREF(sigstack); ^ /home/oceanfish81/workarea/llvm-project/llvm/tools/gollvm/gofrontend/libgo/sysinfo.c:374:32: note: expanded from macro 'SREF' #define SREF(stag) struct stag stag ## ref ^ :52:1: note: expanded from here sigstackref ^ /home/oceanfish81/workarea/llvm-project/llvm/tools/gollvm/gofrontend/libgo/sysinfo.c:462:6: note: forward declaration of 'struct sigstack' SREF(sigstack); ^ 1 error generated. ninja: build stopped: subcommand failed.
