The package emacs-gtk+x11-1:29.4-12.el10 was available from appstream in 10.1 but the upgrade to 10.2 emacs-gtk+x11-1:29.4-13.el10 is missing. I’m using the Mate Desktop through Skips Copr repo. There’s no equivalent I can build from Koji.
It doesn’t exist in RHEL 10.2 either. I guess that would explain why Rocky also doesn’t have it.
EDIT:
I’ve found it in the devel repo.
root@vault:~# dnf list --enablerepo=devel emacs* | grep -i gtk
emacs-gtk+x11.x86_64 1:29.4-13.el10_2 devel
Also confirmed by a quick search on pkgs.org here: https://pkgs.org/search/?q=emacs-gtk%2Bx11
Enabling the devel repo worked, thanks for looking there. The other choice was to get the RL10 source for emacs and just build that package with mock.
