[Solved]Problems installing ghc

After installing ghc, if I try to execute any Haskell file I get the following error:

/usr/local/lib/ghc-7.8.3/bin/ghc: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

I have read that some people have run into the same error but only using other programs, not ghc.

Some of them have solve this problem via some symbolic links in /lib and /lib64 but none of those solutions have worked for me so far.

The output of ldd /usr/local/lib/ghc-7.8.3/bin/ghc shows these missing files too:

Re: [Solved]Problems installing ghc

As suggested on the wiki: https://wiki.archlinux.org/index.php/Haskell

pacman -S ghc

Re: [Solved]Problems installing ghc

Lies, the ghc package does not put files in /usr/local/

Re: [Solved]Problems installing ghc

Uhmmmm

I have installed it with pacman -S ghc but after that I also installed cabal-install and I did a cabal update and I installed ghc-mod from cabal.

Could that have been the problem?

Re: [Solved]Problems installing ghc

If you did that as root and for some reason cabal installed another ghc for ghc-mod, that would explain the files in /usr/local.

Re: [Solved]Problems installing ghc

And how can I uninstall it or fix the problem?

The only thing I found related to this on the wiki weren't of much help:

Removing packages
There is no easy way to do it.

Re: [Solved]Problems installing ghc

I managed to solved that problem as stated here: http://www.linuxquestions.org/questions … 175466995/
this is:

cd /lib64
ln -s libncurses.so.5 libtinfo.so.5

But now it doesn't load the prelude:

$ghc Main.hs
Main.hs:1:1:
    Could not find module ‘Prelude’
    Use -v to see a list of the files searched for.

Re: [Solved]Problems installing ghc

Symlinking like this may come back to bite you. At least make a note about it.

Re: [Solved]Problems installing ghc

Problem solved.

The problem was that I wasn't doing a clean install, since I had used (I didn't remember it, sorry) a third party script to install haskell without having read it before. After that, since the script threw an error I supposed that it hadn't installed anything, but clearly I was wrong.

After removing everything that was not supposed to be there and doing a clean install everything runs smoothly
