bug#43874: ’corrode’ fails because ’ghc-language-c’ wrong version

[zimoun]

Dear,

Using Guix a0d4aa2, the package ’corrode’ fails to build because:

--8<---------------cut here---------------start------------->8---
Configuring corrode-0.1.0.0...
Setup.hs: Encountered missing dependencies:
language-c >=0.4 && <0.6
--8<---------------cut here---------------end--------------->8---

and the package ’ghc-language-c’ had been updated to 0.8.1 by the commit
19b29882878a6558e5f16d587265eb3a0c0cdec6 (Jan. 2017).  So the package is
probably broken since 3 years.

Four fixes are possible:

 1. add the package ’ghc-language-c@0.5.0’ introduced by 
2d2388e243d31f00b31b36b8ada76876b6fdacf2.
 2. turn the package as “private” or at least deprecated.
 3. move it to guix-past.
 4. remove it. (Note that upstream is stalling; last commit 4 years
 ago.)


I am in favor of option #4.  Or maybe someone wants to fix?


WDYT?

All the best,
simon
