msys2/mingw64 build failure #16

Closed Alex-Gamper closed 3 years ago

Hi AdaCore

The latest build of Gnat-llvm fails under msys2/mingw64. Below is the log> Note that the undefined SO_Ref symbols are related to removal of unused functions in GCC (specifically repinfo.ads/adb) which was commited to Git on 17th Dec 2020 "[Ada] Remove unused subprograms in validsw". So their seems to be a disjoint between GCC and gnat-LLVM ??. The issue with LLVM_wrapper.cc seems to be with my LLVM environment, which I think I can resolve

Thanks Alex

For the back_end.adb error, you indeed need to use a slightly older version of GNAT sources, until the next sync, e.g. stop at commit acf190b208ae6883e94b.

The llvm_wrapper.cc issue is unrelated, and most likely due to a LLVM version mismatch: GNAT LLVM currently requires LLVM 10.0.x, you are probably using 11.0. Upgrade to 11.0.1 will be done in the coming weeks.

Hi Arno

Understood, and thanks for the quick response !

For your information, the latest GCC master sources should now be usable again.
