When building without GL renderer the compiler prints the following
warning:
../clients/subsurfaces.c: In function ‘egl_state_create’:
../clients/subsurfaces.c:225:35: warning: passing argument 1 of
‘weston_platform_get_egl_display’ makes pointer from integer without a
cast [-Wint-conversion]
225 | weston_platform_get_egl_display(EGL_PLATFORM_WAYLAND_KHR,
| ^~~~~~~~~~~~~~~~~~~~~~~~
| |
| int
...
Define the fallback implementation of weston_platform_get_egl_display
to take an integer which is the underlaying datatype of EGLenum.
