Re: [Haskell-cafe] Packages all screwed up

AFAIK GHC on Windows comes with it's own mingw, but I'm not sure if the toolchain is complete. But I wouldn't try to reinstall core packages anyway. They are best picked from installation package. Best regards, Krzysztof Skrzętnicki 2011/2/1 Arnaud Bailly

I started that way but quickly ran into issues about compilers toolchain for certain packages: I am on windows and some core packages require mingw toolchain.

This is the easiest way conceptually. You can also try to --reinstall every package that 'ghc-pkg check' report is broken. If you pick up the right version and compilation options will match there is a high chance you can fix this state. I've done this before and it worked. Best regards, Krzysztof Skrzętnicki

Hi, Thanks for your answers.

I did

...

cabal upgrade yesod

As for the user/global issue, I think I tried a user install, this is default isn't it?

Looks like I will have to reinstall everything :-(

Hello, I recently tried to upgrade some package (eg. yesod) and it seems that, in the process, I screwed up my Haskell packages setup. When I am trying to do a simple:

...

ghc --make Crete1941

What command(s) did you issue to "upgrade some packages?" Were you trying to do a user or global install?

When ghc loads packages, I've had cases where packages in the user db would shadow packages in the global db, causing *other* packages in the global db to report as "broken".

Thanks, Antoine
