Hi.
I'm installing the Haskell Platform om my Linux box and need some tips on how to structure the files on the OS. I need to install and use both GHC 6.12.3 and GHC 7.0.2. Hence I want to separate these installations. I've setup two directories, one for each platform (related to the GHC):
# ls -d -1 $PWD/*.*
/usr/haskell/2010.2.0.0
/usr/haskell/2011.2.0.0
I've installed GHC-6.12.3 in "2010.2.0.0" and will install GHC-7.0.2 in "2011.2.0.0".
My question is more related to where I should install the packages. When I install a package using "runhaskell Setup ..." I assumed this to ONLY be installed for the version of GHC I'm using when installing it. Am I right about this?
Having $PATH pointing to GHC-6.12.3 I've done this when installing packages, to add them to "2010.2.0.0":
- - - - - - -
cd /usr/src
tar xzf transformers-0.2.2.0.tar.gz
cd transformers-0.2.2.0
runhaskell Setup configure --prefix=/usr/haskell/2010.2.0.0/
runhaskell Setup build
runhaskell Setup install
- - - - - - -
Later when I switch to GHC-7.0.2 I plan to install the packages into the "2011.2.0.0" directory in stead.
Is this a good way to structure several Haskell installations on the same system? Is there a "best practice" on how to structure the files? I want to get this right from the start, to avoid having to go back and re-arrange everything.
