Hi,
(Well, something appears to me weird: rebuild Gnash which is a C++
software using another toolchain implies a Rust-world rebuild.)

Hum, ok.

Hum, this “right” looks weird to me. I read from (gnu packages gcc):
--8<---------------cut here---------------start------------->8---
;; Note: When changing the default gcc version, update
;; the gcc-toolchain-* definitions.
(define-public gcc gcc-11)
--8<---------------cut here---------------end--------------->8---
Then from (gnu packages commencent):
--8<---------------cut here---------------start------------->8---
(define gcc-boot0
(package
(inherit gcc)
--8<---------------cut here---------------end--------------->8---
Then,
--8<---------------cut here---------------start------------->8---
(define gcc-final
;; The final GCC.
(package (inherit gcc-boot0)
--8<---------------cut here---------------end--------------->8---
And,
--8<---------------cut here---------------start------------->8---
(define-public gcc-toolchain
(make-gcc-toolchain gcc-final))
--8<---------------cut here---------------end--------------->8---
Well, I am lost with the difference between gcc-final and gcc-11.
Last, what lost me is this:
--8<---------------cut here---------------start------------->8---
(define-public gcc-toolchain-4.8
(make-gcc-toolchain gcc-4.8))
(define-public gcc-toolchain-4.9
(make-gcc-toolchain gcc-4.9))
(define-public gcc-toolchain-5
(make-gcc-toolchain gcc-5))
(define-public gcc-toolchain-6
(make-gcc-toolchain gcc-6))
(define-public gcc-toolchain-7
(make-gcc-toolchain gcc-7))
(define-public gcc-toolchain-8
(make-gcc-toolchain gcc-8))
(define-public gcc-toolchain-9
(make-gcc-toolchain gcc-9))
(define-public gcc-toolchain-10
(make-gcc-toolchain gcc-10))
(define-public gcc-toolchain-11
gcc-toolchain)
(define-public gcc-toolchain-12
(make-gcc-toolchain gcc-12))
--8<---------------cut here---------------end--------------->8---
compared to ’gcc-toolchain’ which uses gcc-final. Why not gcc-11 as all
the others? It would make it consistent with the rest, no?
Cheers,
