Cabal reports mismatched interface file ways dyn

[Stefan Schulze Frielinghaus]

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
