Old version / uninstallation confusion

[mcandre]

I downloaded the Haskell Platform 2012.2.0.0 32bit Mac installer and began running it.

It soon popped up with an error about previous versions being installed. The Wiki says to use the Uninstaller program: sudo /Library/Frameworks/GHC.framework/Versions/Current/Tools/Uninstaller.

http://www.haskell.org/haskellwiki/Mac_OS_X#Mac_OS_X_10.6_.28Snow_Leopard.29_and_10.7_.28Lion.29

Evidently this didn't remove much, because the Haskell Platform 2012 installer says I should use uninstall-hs instead.

I ran uninstall-hs thru MYLATESTVERSION, and that wasn't enough either. It said to run with the --remove option.

So I ran uninstall-hs thru MYLATESTVERSION --remove, and it raised about a thousand errors.

So I ran sudo uninstall-hs thru MYLATESTVERSION --remove, and at the end of the output, uninstall-hs says that traces of old Haskell files are STILL on my system. Ack!

Nevertheless, after that kerfuffle, running the Haskell Platform installer all over again appears to be fully operational. I just wish that this installer would run the proper commands for me, because there's a significant amount of hassle involved in cleaning the development environment.

Specs:

Thank you for fixing the wiki page!

Could you be more precise about what you expected the installer to do? Did you want it offer to perform the sudo uninstall-hs for you?

Can you suggest a better wording for the message:

-- To actually remove these files, sudo run the command again with --remove -- To generate a script to remove these files, run the command again with --script

such that you would have realized you needed to run the --remove version with sudo the first time?

uninstall-hs is notable hesitant to do anything because it is really destructive.
