[bug#50217] [PATCH] gnu: Add c2ffi-11.0.0.

[Ludovic Courtès]

Hello,

muradm <mail@muradm.net> skribis:

> * gnu/packages/cpp.scm (c2ffi): New variable.

Overall LGTM, modulo the following minor issues:

[...]

> +(define-public c2ffi
> +  (let ((commit "f50243926a0afb589de1078a073ac08910599582")
> +        (revision "1")
> +        (c2ffi-sha256 "17j73yb6v3lfvwwicl2f3yg141iz2dk1rf874qzqs5bkq64ldjsj"))

Normally, we only provide upstream releases.  If you think we need this
specific commit, could you add a comment explaining why?

Please leave the base32 sha256 string where it’s used, within the
(base32 …) expression (it’s a macro that decodes base32 at
compile-time.)

> +         #:tests? #f))

It would be best to run tests.  Alternatively, if this is not feasible,
please add a comment explaining why we’re skipping them.

> +      (synopsis "Clang-based FFI wrapper generator")
> +      (description "tool for extracting definitions from C, C++, and
> +Objective C headers for use with foreign function call interfaces.")

Please write full sentences, as per
<https://guix.gnu.org/manual/en/html_node/Synopses-and-Descriptions.html>.

> +      (license license:gpl2))))

Is it GPLv2-only?  Unless it’s explicitly stated, it’s probably
GPLv2-or-later (‘license:gpl2+’).

Could you send an updated patch?

Thanks!

Ludo’.

as muradm didn't respond, i took the liberty to addressed the concerns.

i don't know how to credit the original author, so feel free to
fix that part.

let me know if there's anything else to fix.

For cross-compiling c2ffi, this needs to respect #:tests?, because
tests cannot be run when cross-compiling.  This would be detected by
"./pre-inst-env guix lint".

Isn't it the other way around?  Looking at the git repo, the git tag is
v12.0.0.0, not 12.0.0.0, and Guix strips version prefixes like "v", "V"
and "version-".  Also, IIUC, the current consensus is that home pages
and source git repos are separate things, even if sometimes their URL
coincides, so the URL may need to be copied into the 'url' field.

Greetings,
Maxime.

Is clang (the C compiler) required to compile c2fii, or would the usual
gcc suffice?  If the former, I would add a comment

  ;; only supports compilation with clang, gcc does not work here

or the like.  Is the version of clang and LLVM used for compiling c2ffi
important?  If not, I would write (native-inputs (list clang llvm))
such that the default clang and LLVM version in Guix is used.

Greetings,
Maxime.

thank you for the excellent suggestions Maxime! and sorry for being
sloppy with guix lint and others!

v5 should address everything that you pointed out.
