Haskell：安装hsc2hs

Question

When I try to install hsc2hs with the command

cabal install hsc2hs

the following error was returned:

Main.hs:14:0:
     fatal error: ../../includes/ghcconfig.h: No such file or directory
compilation terminated.
World file is already up to date.
cabal.exe: Error: some packages failed to install:
hsc2hs-0.67.20120610 failed during the building phase. The exception was:
ExitFailure 1

Answer 1

hsc2hs is distributed together with GHC.

If you for some reason want to build a newer or modified version, you'll have to build it together with GHC itself.
