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?
