emerge --info app-editors/neovim

Hi, Happy New Year!
I was unable to compile neovim due to this error:

---

In file included from /usr/include/msgpack/pack_define.h:13,
                 from /usr/include/msgpack/pack.h:13,

So I asked for help on Gentoo forums and I was able to resolve the issue with these two commands:

emerge -av dev-cpp/msgpack-cxx
emerge -av neovim

Please see emerge --info attached.
Here is the link to the forum where the problem was resolved.

I'll try to dig into it, but unfortunately I can't reproduce the error. For me:
$ emerge --search msgpack-cxx && nvim --version

IIRC, there is enough to install `dev-libs/msgpack` (and it **is** in DEPEND).

I don't know why didn't reporter had it installed (and so faced the issue), but I guess neovim is fine with with cxx version too.

(btw, I either don't have cxx version and have nvim building fine)

[Comment 3 Ioannis Galanommatis 2024-09-17 10:20:46 UTC]

I had the same problem upgrading from neovim 0.9.5 to 0.10.1-r1.

dev-libs/msgpack-6.0.0-r1 does not install any headers under "msgpack/predef".
It was dev-cpp/msgpack-cxx-6.1.0 that provided msgpack/predef/other/endian.h

So, only after installing msgpack-cxx I was finally able to upgrade neovim.

Another case that needs msgpack-cxx

As happened to original author, msgpack does not provide endian.h for me.

$ qlist dev-libs/msgpack | grep include
/usr/include/msgpack.h
/usr/include/msgpack/fbuffer.h
/usr/include/msgpack/gcc_atomic.h
/usr/include/msgpack/object.h

0.10.[12] have msgpack in the DEPENDs. This can be closed.

Thanks a lot!
