I forgot to mention there are patches attached to this.
Hi, John Soo <jsoo1@asu.edu> skribis: > When compiling with ghc, I have been getting the message that the following > packages have invalid package databases.

Thanks, Ludo’.
Hi Ludo and guix, Let me explain my problem. Maybe there is some other explanation here and these patches aren’t necessary. When I have stylish-haskell installed I have troubles compiling anything using plain ghc. I want to use the ghc packages in the profile but for some reason ghc reports the database is invalid because of at least stylish-haskell and I think I’ve seen hoogle as well. > Does it hurt in practice, or are these invalid databases shadowed by the > one created in the profile? I’m not sure what you mean here. I think I dod not explained my problem well enough. Does the explanation above make sense? Another possibility is the duplication of path variables in tmux where I usually operate. Thinking now, maybe another explanation is because stylish-haskell and ghc-stylish-haskell are fighting each other? They are duplicate packages and maybe if one is removed it will be ok? > Should we add a phase in ‘haskell-build-system’ that systematically > removes package databases? I don’t think so. I like having the profile packages. A lot of times I prefer to use plain ghc with the profile packages over cabal or another tool so I’m happy to have the packages in the database. The ones I was considering removing were ones that primarily provide a binary to use - hoogle and stylish-haskell are primarily used as binaries. However on second thought if I wanted to use them as libraries I think I would be confused as to why I could not. Overall I am leaning towards finding some other solution. Thanks everyone! John
I have not experienced this issue in a long time. I may come back to it if it ever happens again.
