Newbie question: How do I install and use cabal-meta?

[benjamingorman]

I'm trying to use cabal-meta to install gtk2hs, following the instructions at https://github.com/gtk2hs/gtk2hs. Having downloaded the package using 'cabal install cabal-meta', should I then navigate to the tarball, unzip it and build it from source - adding the binary to my path?
I just got started using Arch Linux so basic things like this are confusing me.

cabal install cabal-meta should install cabal-meta to ~/.cabal/bin. Make sure that folder is in your path.

[benjamingorman]

Ok thanks, that's worked. However attempting to 'cabal-meta install' in any directory gives an error; "please run: cabal install cabal-src", which is not remedied by installing cabal-src.

[gregwebs]

hmm, is cabal-src reachable from your $PATH ?

[benjamingorman]

Checking directories in my path reveals that 'cabal-src-install' is reachable, but 'cabal-src' is not.

[gregwebs]

oh, right, the executable is cabal-src-install. What is the result of which cabal-src-install?

[benjamingorman]

/home/ben/.cabal/bin/cabal-src-install

[gregwebs]

That is bizarre. This should probably work for now:

cat sources.txt | xargs cabal install

Thanks Greg!
