Re: Issues with Haskell's ghc

[Prateem Mandal]

Initially gcc-toolchain was also in adhoc list. Now I have installed it as
well. Here are the steps I took

Haskell Steps (doesn't work)
0. Initial state
user@machine:~$ guix package -I
hello 2.10 out /gnu/store/md2plii4g5sk66wg9cgwc964l3xwhrm9-hello-2.10
emacs 26.2 out /gnu/store/fbf0h779z46cl55vdciv00m8s0ccfnyb-emacs-26.2
bash 4.4.23 out /gnu/store/qn1ax1fkj16x280m1rv7mcimfmn9l2pf-bash-4.4.23
guile 2.2.6 out /gnu/store/zp53jz14ql8syglh4nyrwmq2awvfirb8-guile-2.2.6
glibc-locales 2.28 out
/gnu/store/bb9alx1ap57pz0vmx7p1r8qk0lxxfg3x-glibc-locales-2.28
gcc-toolchain 9.1.0 out
/gnu/store/aqv6njg05w2yqh8krgrjy0wcbfxb4nn3-gcc-toolchain-9.1.0
1. Create project folder
user@machine:~/programs/haskell/$ mkdir test
user@machine:~/programs/haskell/$ cd test
2. Create a simple Main.hs file
user@machine:~/programs/haskell/test$ cat <<EOF >> Main.hs
> main :: IO ()
> main = putStrLn "Hello"
> EOF
3. Open a guix environment
user@machine:~/programs/haskell/test$ guix environment --ad-hoc
cabal-install coreutils gcc-toolchain ghc binutils glibc gmp libffi
[guix] user@machine:~/programs/haskell/test$
4. Set/Unset few env variables required to build haskell
[guix] user@machine:~/programs/haskell/test$ unset GHC_PACKAGE_PATH
[guix] user@machine:~/programs/haskell/test$ export
GUIX_LD_WRAPPER_ALLOW_IMPURITIES=y
5. Create .cabal file using "cabal init"
[guix] user@machine:~/programs/haskell/test$ cabal init
6. Update cabal
[guix] user@machine:~/programs/haskell/test$ cabal update
7. Build project
[guix] user@machine:~/programs/haskell/test$ cabal new-build
8. Execute project
[guix] user@machine:~/programs/haskell/test$ cabal new-exec test
