One problem I had was while installing Lehksah. ( It was you who pointed me to the solution, thanks. ) The last problem was for installing wxhaskell from the source. The first part compiled just fine, but the second wouldn't with a package problem. I didn't want to bother searching what the problem was, so I thought it was faster to reinstall ghc and compile wxhaskell then. (it worked) Also, I think it's been a while I managed to do a cabal upgrade which didn't stop on a dependency issue. Since I didn't write down the exact problems I had, I'm attempting a fresh install, and I'll write down what happens as I go. 1) Installing GHC 6.10.2 from the tarball, I decided to give it a try to ./configure --prefix="/home/david/local" 2) Adding /home/david/local' to my PATH 3) I find a binary for cabal-install 0.6.0, 4) cabal update 5) cabal install cabal-install Proceeds to download and compile HTTP-4000.0.6, then zlib-0.5.0.0 which fails because I don't have zlib.h on this new system. da...@pcdavid2:~$ sudo apt-get install ... well there is no zlib-dev, libzlib-dev available on Jaunty. there is a zlib1-dev which fails to install, and a zlib1g-dev which works. da...@pcdavid2:~$ cabal-0.6.0 install cabal-install again. This time zlib-0.5.0.0 compiles, but then : /usr/bin/ld: cannot find -lgmp da...@pcdavid2:~$ sudo apt-get install libgmp3-dev da...@pcdavid2:~$ download/cabal-0.6.0 install cabal-install againagain. This time all goes well except that: Installing executable(s) in /home/david/.cabal/bin why the hell would cabal install binaries in a subdirectory of a hidden directory. Why not /home/david/bin or /home/david/local/bin ? Ok so I find out the setting to change in .cabal/configure, but there's already two packages installed and downloaded there, and I don't know how to change them to the correct location. So, deleting .cabal and local, reinstalling ghc. I kept the de-tarred directory around, so it's really quick. cabal-update again, make sure config has the right path. oops. Cabal thinks zlib is still around, I thought I had deleted that. Looks like reinstalling ghc didn't rewrite my package list. removing .ghc and trying again. Now something else. da...@pcdavid2:~$ ghc-pkg check There are problems in package rts-1.0: include-dirs: PAPI_INCLUDE_DIR doesn't exist or isn't a directory The following packages are broken, either because they have a problem listed above, or because they depend on a broken package. rts-1.0 haddock-2.4.2 ghc-prim-0.1.0.0 integer-0.1.0.1 base-4.1.0.0 ...
