Re: [Haskell-cafe] can't build testpack

tried that version, it gets rid of that error message but now i have this one: ezekiel-smithburgs-macbook-pro-15% cabal --flag=split-base configure -p Configuring testpack-1.0.0... ezekiel-smithburgs-macbook-pro-15% cabal build Preprocessing library testpack-1.0.0... Building testpack-1.0.0...

Use -v to see a list of the files searched for. i'll start reading the cabal user guide and see if i can figure it out on my own, but i figure progress on this should be up on the list so if someone else has this problem, they can find this and solve it on their own. also, if someone else can figure it out before i do, that's cool too. thanks for your help so far!

Ok, sorry for the confusion, I should have checked it before: testpack doesn't really need base-4, it needs base-3.The right dependency line is (for both 6.10.1 and 6.8.3):

Build-Depends: base >= 3 && < 4 , containers, random

I really need to get some sleep...

In short: "cabal configure && cabal build" fails, whereas "cabal install" builds fine. Looks like a bug in cabal-install. Am I right?

testpack builds fine for me. In the original .cabal file there are following lines:

Now that I think about it you didn't actually said what is your GHC version. Knowing that you can replace lines above with one line that matches your specific configuration.

GHC 6.8.3 : Build-Depends: base >= 4, containers, random GHC 6.10.1 : Build-Depends: base >= 3, containers, random

Please take care to restore and modify the original file.

I think you should read Cabal user guide. This will save your time in the future: http://www.haskell.org/ghc/docs/latest/html/Cabal/index.html

I *hope* those changes will fix your installation. I can't really test it, because testpack build fine with my version of cabal:

Perhaps it may also be the difference of installing with "cabal install" and "runhaskell Setup build".

solution to that problem:

deleted the lines from "If flag(splitBase)" on and changed base in Build-Depends to base >= 4.

Well, this is exactly what I suggested in the first place:

...

This error is due to usage of old base package in version 3.> In .cabal file add dependency on base-4, in form "base >= 4".

Regarding second qustion:

...

random 1.0.0.1 is installed, i've verified that. what does this error mean?

It means that .cabal file fails to specify dependancy on random package. Add dependancy on "random" package next to "base>=4". This should help.
