在Ubuntu Server 12.04上安装最新的Haskell源时出错

Question

I trying to install the latest ghc (ghc-7.8.4-src.tar.bz2) on my ubuntu server version 12.04.

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04 LTS
Release:        12.04
Codename:       precise

I know ghc needs a pre existing installation to compile. So I tried with sudo apt-get install ghc and sudo apt-get install haskell-platform . Either case gives me the below error when I run sudo make install . i) Any ideas on solving this? Also, ii) it takes quite a long time to compile, and even get to this point. So is there a way to vet the compilation before hand?

Installing library in /usr/local/lib/ghc-7.8.4/ghc-prim-0.3.1.0
ghc-cabal: Error: Could not find module: GHC.PrimopWrappers with any   suffix:

make[1]: *** [install_packages] Error 1
make: *** [install] Error 2

Ok, solved this with the help of the fine folks on IRC (#haskell). Turns out that compiling ghc from source is really reserved for hacking on the compiler itself. So I was recommended the GHC binary package. That's presently GHC 7.8.4 .

From there, ./configure and sudo make install worked for my platform. With a working ghc, you can then get the latest Cabal . Cabal library needs to be built, and cabal-install is a binary. They are currently both at 1.22.0.0.

Hope this helps someone.
