When xscreensaver is emerged with USE= gtk -gdk-pixbuf, the build fails in the configure phase even though in the log it just shows a warning because GTK is being used but there is no GDK-Pixbuf.

I think gtk is a USE-Flag that should depend on USE-flag gdk-pixbuf instead of being independent from each other.

Comment 3 Tom Gillespie 2022-07-11 08:14:20 UTC
This issue is a bit more tangled (I'm looking at 6.04). If you set -gdk-pixbuf then in theory you should be able to get everything to build if you add -gtk and -png. However the ebuild has an incorrect use flag dependency stating that opengl requires png to be enabled, which is false.
Comment 4 Pascal Jäger 2022-10-17 09:21:46 UTC
I filed a bug upstream because this is a just a warning, which is kind of confusing.
Comment 5 Pascal Jäger 2022-10-17 10:20:05 UTC
This IS really tangled.
So, as far as I can tell the problem here is, that you have to have either --with-gtk or --with-motif, otherwise make install will fail. Since we do --without-motif in the ebuild, there is not much sense in having gtk as a use-flag. 

Then on the other hand, the build is fine as long as I do things manually. (So ./configure, make, make install) but it's not when I do it in portage. I think that is a problem of the script. This one exits with status 1 as soon as there is a warning. Portage interprets this as an error end exits.
Comment 6 Pascal Jäger 2022-10-18 08:48:38 UTC
Just for future reference on how this works: 

As I initially thought --with-gtk and --with-motif controls which kind of toolkit is used to display the xscreensaver-settings menu. 
BUT: Motif is unmaintained and we therefore do --without-motif in the ebuild. 

Now this would render the USE-flag --with-gtk obsolete, it it weren't for the non-gtk install patch (

So, it is possible to build with --without-gtk and --without-motif now. One just don't get the xscreensaver-settings program. 

Now coming to this bug. --without-gtk and --without-motif fails in because upstream does not support building it without both anymore. (I guess, could be a mistake as well rather than a conscious decision.) Therefore we need to disable some exit codes of the script. This (among other things) is what I am doing with the new patch for version 6.05 (, line 12 in the patch)

This will give us the ability back to build with USE="-gtk -gdk-pixbuf -png". (line 20 and 28 in the patch)
This patch also alters the exit code for when gtk is found but gdk-pixbuf is not. (I think this is a mistake by upstream, because the script even mentions that it should be possible to use the png library when gdk-pixbuf is not found.

I wrote upstream a bug report via email for both problems. I think at least the latter should be fixed.

    * New patch for handsys manners
    * Building with USE="-opengl" is not supported anymore
    * Also added a patch for -gtk builds, set GTK_SHAREDIR because when build
      with USE="-gtk" it is not set and then installs .service file into /
    * Building with USE="-xft" is not supported anymore
    * Delete .service file when USE="-systemd"
