mlitchard@apotheosis:~/monad-control$ cabal install Resolving dependencies... Configuring monad-control-0.2.0.1... cabal: Error: some packages failed to install: monad-control-0.2.0.1 failed during the configure step. The exception was: ExitFailure 11
note: I've been trying to use the cab command to manage my packages, I get the same error as above when I use cab instead of cabal.I mention this just in case there is some unforseen problem having to do with cab/cabal interaction.
Has anyone experienced this problem, or know what I can do to get more useful error messages that might reveal the cause of the breakage?
You might learn more by issuing the configure / build steps manually (I think `cabal configure` will produce an error). Upping the verbosity will also help: # get pages and pages of details: $ cabal install --verbose=3 I would first suggest trying cabal-dev, though (cab can delegate to cabal-dev now too, but I haven't played with it yet). $ cabal-dev install yesod-0.8 will either work or fail in a way that we can more easily reproduce. --Rogan
