Description Gianluigi Papia 2019-11-12 21:34:07 UTC

emacs does not start, the error is the following:
Undefined color: "WINDOW_FOREGROUND"

According to emacs dev (?), this is outside of Emacs control. There are some files that expects to be run through the preprocessor, but isn't. (sic)

It seems that this happens because KDE's defaults apply its color and font definitions even to applications that weren't compiled for KDE. Interesting link (from line 1203): https://fossies.org/linux/emacs/etc/PROBLEMS

I try to remove /usr/share/kdisplay/app-defaults/Emacs.ad or make this file empty. In these cases, the error is now the following:
Undefined color: "FOREGROUND"

I want to keep the breeze dark style for my GTK applications (System Settings > Application Style > GNOME Application Style (GTK)) so I didn't uncheck anything in those GTK settings.

STEPS TO REPRODUCE
1. 
2. 
3. 

OBSERVED RESULT
Undefined color: "WINDOW_FOREGROUND"

Created attachment 123878 [details]
GTK Config

The emacs version is:
GNU Emacs 26.3 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.10) of 2019-08-29

For information, emacs runs with option -nw or -Q

In attachment, the GTK style configuration in System Settings.

The answer was just there: https://wiki.archlinux.org/index.php/Emacs#Emacs_fails_to_start_with_the_error_message_'Undefined_color:_%22WINDOW_FOREGROUND%22'

I installed the the mcpp package and now all work fine!

Thanks, looks like this is not a Breeze GTK bug then.
