如何在Windows 64位上为ghc 7.10设置cabal

Question

I have just downloaded the newest GHC 7.10.1 version, and I am trying to set up the cabal system to make it work. But I couldn't find the 64-bit cabal binary for 64 bit windows.

Haskell Platform does not have 7.10 yet. So I went to https://www.haskell.org/cabal/download.html , but there is only binary for 32-bit windows. I tried to use that version to cabal update , but cabal.exe just crashed while setting up the initial config.

I was wondering what's the procedure to set up cabal for 64-bit GHC?

Answer 1

Here is what worked for me.

I used a previous version of 64-bit GHC, such as those in Haskell Platform, to compile a cabal.exe , and use it to do:

cabal install cabal-install

(boot-strapping).

After this, the cabal.exe installed into the local cabal directory was 64-bit and worked just fine.

Note: I have tried MinGHC 64-bit as @Zeta hinted, but the cabal.exe there was also 32-bit. It seems to be incompatible with the 64-bit GHC system, and gave me crashes just as the 32-bit cabal.exe downloaded from the official website.
