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.

Hi John,

Oh, I see!  I wonder if it possible to have a more convinient

haskell-for-a-casual-developer like package or:

parameterize the command itself, say:
guix install ghc -option1=blah, -option2=blah,
and provide default options as well?

In the very least, a warning message explaining this after:
guix install ghc

Might do.

Lots of ideas :-)

Cheers,
yasu

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,

Good point.

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!
