从源代码安装haskell平台时出错

Question

I need to install from source files the haskell platform so as indicated in the instructions installed cabal, ghc and other libraries for Ubuntu that are needed.

When I try to install the haskell platform with the command:

./platform.sh /home/myuser/haskell/ghc-7.10.2-x86_64-unknown-linux-deb7.tar.bz2 -j 3

I get the following error:

***
*** Building hptool
***
Building hptool-0.1...
Preprocessing executable 'hptool' for hptool-0.1...
***
*** Running hptool
***
Error when running Shake build system:
* 3
Error, file does not exist and no rule available:
  3

and I don't find anyone with same error. The haskell platform version that I have downloaded is haskell-platform-7.10.2-a

Answer 1

When using the ./platform.sh script you can't pass a build option like -j 3 .

Try building and running hptool manually like this:

cd hptool
cabal sandbox init
cabal install -j3

cd ..
./hptool/.cabal-sandbox/bin/hptool PATH-TO-GHC-BINDIST SHAKE-TARGET

Run hptool with no arguments to get a list of valid values for SHAKE-TARGET.
