This looks very similar to an issue seen while trying to package
fuzzylite, and debian had a patch for it:
https://salsa.debian.org/debian/fuzzylite/-/blob/debian/sid/debian/patches/fix-tests2.patch
It basically switches to using "catch2" headers instead of "catch"
headers...
A similar patch might work for cpp-mustache?
live well,

Hi Vagrant!
Thank you for your answer, I see what you mean for catch2 instead of catch.
I will investigate by studying the patch you linked.
And btw, thanks a lot for your work with debian!
Kind regards
Hubert

I had a similar failure.

There are several approaches here and I've patches for two of them if
needed (I've attached them):
(1) backport some upstream patches:
- There are 2 catch2 updates, they can be squashed into 1 patch
- We also need a patch for fixing unused variables.
(2) Update cpp-mustache: There is an upstream commit
(https://github.com/kainjow/Mustache/commit/4ed8c0b5a2a43d59394bd6900dc04e738dbf8c02)
that change some version string. I've asked upstream if that was
the 5.0.0 release but so far I got no answer.
https://github.com/kainjow/Mustache/issues/65
(1) is 0001-gnu-cpp-mustache-fix-build-with-newer-glibc.patch
(2) is 0001-bug-reported-upstream-for-release-info-gnu-cpp-musta.patch
I didn't share the patches yet because I was waiting on upstream to
clarify the situation with the lack of 5.0.0 tag.
Denis.

Hi Denis!
Thank you for your answer :) I have downloaded the 2 patches
and I plan to apply it when I have time...
Thanks again for your help!
Kind regards,

I had a similar failure.
> A similar patch might work for cpp-mustache?
There are several approaches here and I've patches for two of them if
needed (I've attached them):
(1) backport some upstream patches:
- There are 2 catch2 updates, they can be squashed into 1 patch
- We also need a patch for fixing unused variables.
(2) Update cpp-mustache: There is an upstream commit
(https://github.com/kainjow/Mustache/commit/4ed8c0b5a2a43d59394bd6900dc04e738dbf8c02)
that change some version string. I've asked upstream if that was
the 5.0.0 release but so far I got no answer.
https://github.com/kainjow/Mustache/issues/65
(1) is 0001-gnu-cpp-mustache-fix-build-with-newer-glibc.patch
(2) is 0001-bug-reported-upstream-for-release-info-gnu-cpp-musta.patch
I didn't share the patches yet because I was waiting on upstream to
clarify the situation with the lack of 5.0.0 tag.
Denis.

Note that I didn't send them to Guix yet.
So if a Guix maintainer (or someone else with good ideas) could tell me
what is the best approach here, I would know which one to send.
Or should I send both in the same patch serie and make the maintainers
choose between both?
Denis.

Note that I didn't send them to Guix yet.
Yes I know, if I can have some happy hacking with it, it will be
an opportunity to deepen my knowledge.
Anyway, I'm still waiting a bit, not having the time yet...
So if a Guix maintainer (or someone else with good ideas) could tell me
what is the best approach here, I would know which one to send.

Good questions :)
Denis.
Happy hacking!

Hello
thank you very much Hubert for your report: errors like the one you
found (packages build failures) are bugs, next time please report them
to bug-guix@gnu.org; better to close a non-bug than to miss an actual
one ;-)
As you can see I've now filed a new bug: bug#63551
Thank you also to Vagrant and Denis for the heads up, please submit
further comments or patches to 63551@debbugs.gnu.org

Please do not wait for an official upstream "release" (git tag,
actually) for cpp-mustache, I guess upstream just forgot to tag it: Guix
is full of "not officially" released or properly tagged packages,
sources are often taken from carefully selected git commits (I've
recently proposed a patch for dia, that is in a very similar situation)
Since commit 4ed8c0b is setting version to 5.0.0 and that version works
(does it?), I'd go for an "update to 5.0.0" patch
My two cents.
[...]
Happy hacking! Gio'

It at least builds fine.
Thanks a lot for the advises.

Hi,
Guix now has cpp-mustanche 5.0 so I think we can close that bug.
