[Haskell-cafe] [OT] GHC uninstall on Linux

[Dusan Kolar]

Hello all,

  Thank you for your replies and tips. The idea of having several 
versions of GHC in parallel is nice, but I don't long for it even if 
space is not a problem.

  To post some resolution: the stuff is (if installed using default 
settings) in the directories /usr/local/bin, /usr/local/lib, and 
/usr/local/share/doc. It is easy to find and remove /usr/local/lib/ghc* 
and /usr/local/share/doc/ghc* directories. Nevertheless, in the 
/usr/local/bin directory, you should search not only for *ghc* but even 
for other stuff that may be part of installation if other components are 
installed as well, they are: hasktags, hp2ps, hpc, hsc2hs, runhaskell.

  From the proposed tools, I gave a try to GNU stow tool. I can 
recommend it as it is easy to use and it can detect conflicts (the way I 
have discovered other files than *ghc* in the /usr/local/bin).

  Thx and regards

    Dusan
