* Bug? Haskell GHC wont' work since ghc@8.6?

This one ought to be very simple to solve (or at least confirm).   Does
anyone use Haskell daily?

I am a very casual user of Haskell (GHC) and when I tried to compile
something just now, I noticed that it can't even compile the simplest
possible program..., unless I downgrade to ghc@8.4 or lower. Newer
versions, including ghc@8.6.5, didn't work, throwing the error message
below instead.

~/co/haskell-tiny-intro/exercise (master *)$ cat a.hs
main = putStrLn "a"

~/co/haskell-tiny-intro/exercise (master *)$ ghc a.hs
Linking a ...
.gcc-wrapped: error: unrecognized command line option '-no-pie'
`gcc' failed in phase `C Compiler'. (Exit code: 1)

Cheers,
Yasu

     Hi yasu, 

 
Compiling with ghc requires a c toolchain (like gcc-toolchain) installed to work. Can you try again after installing gcc-toolchain?    Ghc has not been perfect for me recently but I use it quite a lot.
 

 
Hope that helps,
 

 
John

Hi John,
Thank you, after installing gcc-toolchain, it worked!
Then this is indeed a bug that should be very simple to fix?   Just
require gcc-toolchain (or some of its required features) as a GHC's
dependency?
I am also curious, what kind of testing (if any?) does Guix perform for
packages??  Or is GHC already marked as broken?
(Apology for repeated question marks :-))

 Some should be closed, and bug-guix should be removed from the thread.

As is, ghc does not work after guix install ghc. gcc-toolchain must be
installed alongside it to work.  Maybe the reason for this was to not
propagate particular versions of the gcc-toolchain and possibly conflict
with others.

Thanks!

John

Choosing the C toolchain and propagating one are not really related.  I
mean, one C toolchain could be propagated by default, so then GHC works
out-of-the-box.  And the build transformation ’--with-c-toolchain’
should provide the flexibility to use any other C toolchain variant you
want.  Is it not working as expected?


All the best,
simon

Hi yasu,  

  
This question comes up on the mailing list every so often, but I don’t think it is a bug. I want to be able to choose the c toolchain ghc uses myself. I would rather introduce some Haskell specific documentation.
  

  
We discussed during the guix day that we would love to have some language specific setup documentation. I had issues like this in mind.
