From what I can tell, the only hangup I have is that the "process" package depends on the wrong version of "directory". [blaine@macbook:~/Dropbox/src/berp/compiler Tue Nov 15] 75$ cabal configure Resolving dependencies... Configuring berpcompiler-0.0.3... Warning: This package indirectly depends on multiple versions of the same
Hi everyone. I'm new to haskell (venturing over from python land); i can't figure this one problem out. This has been incredibly difficult to solve, and it is quite discouraging! i'm trying to get berp up and running ( https://github.com/bjpop/berp/). berp-libs installed fine, berp-compiler is hanging up: package. This is highly likely to cause a compile failure. *package process-1.0.1.3 requires directory-1.0.1.0* package cpphs-1.13.2 requires directory-1.1.0.1 package berplibs-0.0.3 requires directory-1.1.0.1 package berpcompiler-0.0.3 requires directory-1.1.0.1 OK so I need to rebuild process so it uses the newest version of directory like the rest of them (I have no idea if this is the right thing to do, but this is what i did with cpphs and it worked). But when I try and build process, it can't find a header on my file that does exist. I also did successfully install from source package manually (using these instructionshttp://www.haskell.org/haskellwiki/Cabal/How_to_install_a_Cabal_packageon the package downloaded from here http://hackage.haskell.org/package/process-1.0.1.3, which worked fine, but didn't seem update the dependency to rely on the newest version of directory (aka still can't configure berp). I don't know where to go from here. Please note: I have installed from source package, so even if I fix this cabal issue I'm not sure it will fix the dependency issue (but who knows, maybe it will). I'm having a hard time scaring up internet resources on where to proceed. What am I doing wrong?
