Hi Simon, Apologies it's taking so long. It's not obvious how to fix this properly, and as a temporary workaround we could create a top-level wrapper script, say `ghc-stage1.sh` that will call Stage1 GHC with the right arguments, just like Hadrian itself does during the build. Will this work for you? Cheers, Andrey

I reported this a few weeks ago, but it still seems unchanged Simon Bash$ ~/code/HEAD/_build/stage0/bin/ghc --version The Glorious Glasgow Haskell Compilation System, version 8.9.0.20190414 simonpj@MSRC-3645512:~/tmp$ ~/code/HEAD/_build/stage0/bin/ghc -c T16566.hs T16566.hs:1:8: error: Bad interface file: /opt/ghc/8.6.4/lib/ghc-8.6.4/base-4.12.0.0/Prelude.hi mismatched interface file versions (wanted "809020190414", got "8064") | 1 | module T16566 where | ^^^^^^
