guix/run-wayland.scm

1;; Runtime packages for a sigil-desktop game as a native Wayland client on Guix:

2;;

3;; guix shell --pure -m guix/run-wayland.scm -- ./build/release/bin/<game>

4;;

5;; GLFW loads every platform library at run time by soname, and

6;; sigil-desktop's dlopen (src/c/dl-search.c) looks in $GUIX_ENVIRONMENT/lib,

7;; which guix shell sets, so no LD_LIBRARY_PATH is needed. Three packages:

8;;

9;; mesa libEGL.so.1, libGL.so.1 and the GL driver (llvmpipe or the GPU's)

10;; wayland libwayland-client.so.0, libwayland-cursor.so.0, libwayland-egl.so.1

11;; libxkbcommon libxkbcommon.so.0, the keyboard map

12;;

13;; Not listed: libdecor (client-side decorations for compositors without

14;; xdg-decoration, i.e. GNOME; it adds ~850 MiB of GTK to the closure and

15;; sway/KDE/wlroots compositors decorate server-side), and libglvnd (Guix's

16;; mesa is built without glvnd, and a vendorless libGLX.so.0 on the path

17;; makes GLFW's GLX fail with "No GLXFBConfigs returned").

18;;

19;; With sigil-graphics 0.11.4 (GL loaded through sigil-desktop) and

20;; sigil-audio 0.12.2 (miniaudio, backends loaded at run time) a game's

21;; NEEDED list is libm, libc and the loader; a game with sound adds the

22;; audio backend library, see run-wayland-game.scm.
