Hi all, I'm trying to compile GHC 8.6.5 using the LLVM backend and dynamic linking. My build.mk file looks as follows: include mk/flavours/quick-llvm.mk DYNAMIC_BY_DEFAULT = YES I can build a stage3 compiler. However while executing `make install` the following error shows up: "inplace/bin/ghc-cabal" register libraries/ghc-prim dist-install "/devel/ghc86/lib/ghc-8.6.5/bin/ghc" "/devel/ghc86/lib/ghc-8.6.5/bin/ghc-pkg" "/devel/ghc86/lib/ghc-8.6.5" '' '/devel/ghc86' '/devel/ghc86/lib/ghc-8.6.5' '/devel/ghc86/share/doc/ghc-8.6.5/html/libraries' NO ghc-cabal: '/devel/ghc86/lib/ghc-8.6.5/bin/ghc' exited with an error: Bad interface file: dist-install/build/GHC/CString.hi mismatched interface file ways (wanted "dyn", got "") I found similar reports [1,2] from 2013 but no solution. Any ideas how to fix this? Cheers, Stefan [1] https://mail.haskell.org/pipermail/ghc-devs/2013-December/003488.html [2] https://mail.haskell.org/pipermail/ghc-devs/2013-December/003507.html
