I need information for correct install or
what are dependencies on ghc ?
I have a Debian System.
Always use your distribution’s packages until they aren’t any or there is good reason not to do so. Try “aptitude install ghc6”.
For my system (kubuntu 7.10) ghc-6.8.2 is not available as a package, only 6.6.1. And there are programs and libraries that can't be used with 6.6.1. Furthermore, in kubuntu 7.10 the libghc6 packages are broken w.r.t the documentation path. To illustrate (I have both libghc6-mtl-dev and libghc6-mtl-doc installed): ben@sarun[1]: ~ > ghc-pkg describe mtl | grep haddock haddock-interfaces: /usr/share/mtl-1.0.1/doc/html/mtl.haddock haddock-html: /usr/share/mtl-1.0.1/doc/html ben@sarun[1]: ~ > ls /usr/share/mtl-1.0.1/doc/html ls: /usr/share/mtl-1.0.1/doc/html: No such file or directory ben@sarun[1]: ~ > locate mtl.haddock /usr/share/doc/ghc6-doc/html/libraries/mtl/mtl.haddock ben@sarun[1]: ~ > ls /usr/share/doc/ghc6-doc/html/libraries/mtl/mtl.haddock /usr/share/doc/ghc6-doc/html/libraries/mtl/mtl.haddock This leads to errors when haddock tries to link to the mtl documentation. It took me quite a while to figure out what the source of this problem was. IME, it is better to install ghc and all the libraries from source. Of course you need to install ghc from the distro package for bootstrapping ghc, but you can delete it after the self-compiled ghc is installed. Cheers Ben PS: Yes, I reported this bug to the package maintainer but I received no response.
