`guix describe`
guix fd4c7a0
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: fd4c7a098a508c1de7a8513c0f3d88d5a0df12e7

I have ghc in my system configuration file.  I have just done a pull and
reconfigure.

`which ghc`
/run/current-system/profile/bin/ghc

I created a one line hello world program:

```haskell
main = putStrLn "hello, world"
```

Then I tried to compile it with ghc.  I get this error.

`ghc Main`                      
[1 of 1] Compiling Main             ( Main.hs, Main.o )
gcc: error trying to exec 'as': execvp: No such file or directory
`gcc' failed in phase `Assembler'. (Exit code: 1)

I have tested compiling the same hello world program with the same ghc
command and it works fine on a none Guix System.

Does the other system have ‘as’ installed?  Install the 
‘gcc-toolchain’ package that provides it and try again.

Usually, this kind of error means that ghc needs to be patched to 
invoke ‘as’ from an absolute file name instead of searching $PATH. 
There may have been good reasons not to do this (such as closure 
size), or it might be an oversight.

Kind regards,

T G-R

Thank you for the suggestion to install `gcc-toolchain`.  It addresses
that error.  The next error I ran into was:

[1 of 1] Compiling Main             ( Main.hs, Main.o )

First I tried adding glibc to my system configuration and reconfiguration.
That did not work.

This is what got it to work.

* Create a user manifest that includes ghc, gcc-toolchain, glibc
* Run `guix package --manifest=manifest.scm`
* Add exports from package output to .zprofile
* `source .zprofile`

# Questions

I used package search to search for `as`.  I could not find it.  Thanks
to the tip from Tobias Geerinckx-Rice I know it is in `gcc-toolchain`.
But when I look at `gcc-toolchain` there is no mention of `as` the
program in the synopsis, description or dependencies.  Is there a better
way to search for a program that is part of a larger package like this?

ghc, gcc-toolchain and glibc needed to be in a user manifest.  When does
a package need to be in a user manifest for it to work?

gcc-toolchain and glibc in a user manifest where required as
dependencies for ghc.  Should this be noted in the ghc package
description?

Using recent Guix, I get:

$ guix describe
Generation 28	Sep 06 2023 14:54:50	(current)
  guix 6113e05

$ echo 'main = putStrLn "hello, world"' > foo.hs
$ cat foo.hs
main = putStrLn "hello, world"

$ guix shell -C ghc gcc-toolchain -- ghc foo.hs
[1 of 1] Compiling Main             ( foo.hs, foo.o )

$ ./foo
hello, world

Can we close this bug report?  Do you still have that issue?

Cheers,
