Windows bindists are quite broken
mingw32 binary distributions are currently quite broken:
$ wget https://gitlab.haskell.org/ghc/ghc/-/jobs/1805153/artifacts/raw/ghc-x86_64-windows-release.tar.xz
$ tar -xf ../ghc-x86_64-windows-release.tar.xz
$ cd ghc-9.10.0.20240310-x86_64-unknown-mingw32/
$ bin/ghc --info
ghc-9.10.0.20240310.exe: could not detect mingw toolchain in the following paths: ["C:\\msys64\\home\\ben\\tmp\\ghc-9.10.0.20240310-x86_64-unknown-mingw32\\lib\\..\\mingw","C:\\msys64\\home\\ben\\tmp\\ghc-9.10.0.20240310-x86_64-unknown-mingw32\\lib\\..\\..\\mingw","C:\\msys64\\home\\ben\\tmp\\ghc-9.10.0.20240310-x86_64-unknown-mingw32\\lib\\..\\..\\..\\mingw"]
It appears that many things that should be in the root of the binary distribution are instead now in lib
(including mingw/
):
$ ls lib/
a.exe config.guess config.status default.host.target.in doc ghc-usage.txt install-sh llvm-targets mk README x86_64-windows-ghc-9.10.0.20240310
bin config.log config.sub default.target docs-utils html latex Makefile package.conf.d settings
build.mk config.mk configure default.target.ghc-toolchain ghc-interp.js include lib manpage post-link.mjs template-hsc.h
completion config.mk.in default.host.target default.target.in ghci-usage.txt INSTALL llvm-passes mingw prelude.js wrappers
Moving lib/mingw
to the root of the distribution appears to be sufficient to make the compiler functional.
