Re: [web-devel] GHCi runtime linker: fatal error: I found a duplicate definition for symbol (Yesod)

Hello,

I've basically given up. Evertime there is an update to yesod, I run these commands to fix everything:

rm -r ~/.ghc; cd <my project>; cabal install happy alex; cabal install

then I go get coffee, when I come back, everything works.

The "cab" command would ease your package life. http://www.mew.org/~kazu/proj/cab/en/ --Kazu
