Re: New gnome-sdk images with gnome-builder app bundle

[Vadim Rutkovsky <roignac gmail com>]

Hey,

I was running this in jhbuild shell on RHEL7 and I get:

$ xdg-app run org.gnome.Builder
*** Error in `xdg-app': munmap_chunk(): invalid pointer: 0x000000000040801e ***

It seems some libs are either not included in Platform or being discouraged.
