Error when building program that uses Yesod webserver #56

Closed deteego closed 13 years ago

deteego commented 13 years ago

Same project again, this time however there is a linker error which causes my webserver to fail to build

I think this may have something to do with using -fproduction flag to build yesod (in order to get yesod to build)

It definitely seems related, but I've had no trouble with this in the past. I'm sorry to ask this of you, but can you try deleting your .ghc folder and building from scratch? Most likely one of the packages got misconfigured somewhere along the way and cabal hasn't noticed it yet.

Well I have built packages using cabal2arch, so I will have to do a cascade and rebuild again (will take around an hour).

Will report back to see what happens

deteego commented 13 years ago

I rebuilt yesod completely and it builds fine, so something must have happened previously when building the libraries
