This is a brief and bare-bones guide to getting GHC 7.2 and the cabal-install
tool (the two basic things you'll need to do Haskell development) up and running
on a new Linux install.
The instructions given here worked for me, but YMMV. My environment is Debian GNU/Linux, sid(unstable).
First, download tar-ball of ghc.
curl -O http://www.haskell.org/ghc/dist/7.2.1/ghc-7.2.1-x86_64-unknown-linux.tar.bz2
If you are using debian sid, you will encounter the error like there is no gmp library, while you have that. Let's work around then.
sudo ln -s /usr/lib/x86_64-linux-gnu/libgmp.so /usr/lib/x86_64-linux-gnu/libgmp.so.3
./configure
make intall
If you don't have gcc or so, get build-esseintial.
Thanks to mans, we have very useful package on hackage. http://hackage.haskell.org/package/cabal-install-ghc72-0.10.3
So what we must do is simple: Download, unzip, and some work around, done. Some of you want to build anything on build directory.
cd build
Download the package. If its URI was invalid, use the link on the bottom of the page I showed above.
curl -O http://hackage.haskell.org/packages/archive/cabal-install-ghc72/0.10.3/cabal-install-ghc72-0.10.3.tar.gz
tar xf cabal-install-ghc72-0.10.3.tar.gz
cd cabal-install-ghc72-0.10.3
Choose cabal file you want, and rename the other to different name.
mv ._cabal-install-ghc72.cabal ._cabal-install-ghc72.caba
Then fire the boot strap.
If you want global cabal, edit bootstrap.sh like as below.
-SCOPE_OF_INSTALLATION="--user"
+SCOPE_OF_INSTALLATION="--global"
Then boot the bootstrap. If you changed scope as --global, do it with root privilege.
sh bootstrap.sh
If your linux is installed right now, you may not have something to do that.
If your distribution is Debian, Ubuntu, Vine, or something with apt tool,
Perhaps apt-get install build-essential is helpful.
