gl-manifest.scm — lantern

1;; Graphics stack for running a Lantern window (GTK4 + WebKitGTK 6.0 over the

2;; Mesa GL/Vulkan drivers). Use ephemerally:

3;;

4;; guix shell -m gl-manifest.scm -- bash -c \

5;; 'LD_LIBRARY_PATH="$GUIX_ENVIRONMENT/lib" \

6;; ./build/native/bin/lantern run <web-build-dir> --title Slate'

7;;

8;; GTK4 will not map a window unless the Mesa GL/Vulkan drivers are on

9;; LD_LIBRARY_PATH (Guix does not populate it) — hence the LD_LIBRARY_PATH above.

10;; Add LANTERN_SOFTWARE_RENDER=1 if the compositor/GL path misbehaves.
