Subject: bug#52564: Errors building pgtk in Fedora 34 & 35 using --with-xwidgets
Date: Fri, 17 Dec 2021 04:45:46 +0000	[thread overview]
Message-ID: <CY4PR08MB33490675804DA7CFEFD49C428B789@CY4PR08MB3349.namprd08.prod.outlook.com> (raw)

Hello!

Building Emacs pgtk branch, I get compilation errors running make. Started using Fedora 34, but upgraded to Fedora 35 in case I had something outdated but still, same problem. A bunch of the compilation errors refer to the same structs/data types so I have a sample of one of each (but maybe I missed one "type"):

--------------------------------------------------------------------------------

Posted on Reddit about it, two people provided very useful insights:

1. Removing the --with-xwidgets flag allowed me to build.

2. Quote: "The file /usr/include/X11/Xlib.h in your message is from libx11-dev / libx11-devel. Looking at their GitLab CI file, they test against Debian 9 stretch which uses version 1.6.4 (according to https://packages.debian.org/stretch/libx11-dev) whereas Fedora 35 libx11-devel is using version 1.7.3 (according to https://packages.fedoraproject.org/pkgs/libX11/libX11-devel/)"

(link to reddit post: https://www.reddit.com/r/emacs/comments/rht9yw/cant_compile_pgtk_in_fedora_35/)

Being that this is a build of master, I would assume it is low priority :)

Thank you!
Sebastián
