Hi all, As a second option I’ve been working on trying to build using the MSVC ABI (i.e. without MinGW).
Using the latest Clang 11 from the LLVM website and Pthreads-win32, plus removing -lm from target.make, I was able to get quite a bit further running Base configure. However, it fails checking for objc_sync_enter with the following linker errors – any ideas what these could be about? > configure:8038: checking for objc_sync_enter > configure:8038: /C/LLVM/bin/clang -o conftest.exe -g > -I/c/GNUstep/MSVC/x64/include -I/c/GNUstep/MSVC/x64/include > -I/c/GNUstep/MSVC/x64/include -I/c/GNUstep/MSVC/x64/include -x objective-c > -fuse-ld=lld -L/c/GNUstep/MSVC/x64/lib -L/c/GNUstep/MSVC/x64/lib > -L/c/GNUstep/MSVC/x64/lib -L/c/GNUstep/MSVC/x64/lib conftest.c -lpthread > -fuse-ld=lld -pthread -fexceptions -fobjc-runtime=gnustep-2.0 -fblocks > -L/home/Frederik -LSeiffert/GNUstep/Library/Libraries > -L/c/GNUstep/MSVC/x64/lib -lobjc >&5 > conftest.c:119:6: warning: incompatible redeclaration of library function > 'objc_sync_enter' [-Wincompatible-library-redeclaration] > char objc_sync_enter (); > ^ > conftest.c:119:6: note: 'objc_sync_enter' is a builtin with type 'int (id)' > 1 warning generated. > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$SEL > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$SEL > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$CLS > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$CLS > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$CLR > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$CLR > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$CAT > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$CAT > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$PCL > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$PCL > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$PCR > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$PCR > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$CAL > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$CAL > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __start_.objcrt$STR > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > > lld-link: error: relocation against symbol in discarded section: > __stop.objcrt$STR > >>> referenced by C:\tmp\conftest-78a937.o:(.objc_init) > PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash > backtrace. > 0.
