The package exists, it is ’hidden’ – it means not accessible at the CLI
level.  The ’inherit’ copies, so gcc-11 is also hidden, for instance.

--8<---------------cut here---------------start------------->8---
(define-public gcc-4.7
[...]
    (hidden-package
     (package
       (name "gcc")
       (version "4.7.4")

(define-public gcc-4.8
  (package (inherit gcc-4.7)
    (version "4.8.5")

[...]

(define-public gcc-11
  (package
   (inherit gcc-8)
   (version "11.3.0")
--8<---------------cut here---------------end--------------->8---

The package ’gcc’ by itself is not barely useful because you also need
linker etc. Well, you usually need a complete toolchain, named
gcc-toolchain. ;-)

See manual: <https://guix.gnu.org/manual/devel/en/guix.html#The-GCC-toolchain>


So this is not a bug and I miss how what could be improved.  Closing?
