I just built Emacs 26.1 (stable) on Centos 6 (RHEL 6.9). When I fire up the executable with
src/emacs -Q over X11 it shows an empty window with no minibuffer:
I built Emacs without gnutls, but that should be possible. Do I miss any essential libraries?
According to this question the issue might be related to the X-toolkit I'm using (GTK2). Does Emacs 26 not support GTK2?
The build runs fine in a terminal via
src/emacs -Q -nw
I have built Emacs 25 on the same machine and it runs successfully over X11.
