When i try to compile cairo, make shows me this error drm/cairo-drm-surface.c: In function 'cairo_drm_surface_map_to_image': drm/cairo-drm-surface.c:333:2: error: implicit declaration of function '_cairo_surface_is_image' drm/cairo-drm-surface.c:333:2: warning: nested extern declaration of '_cairo_surface_is_image' At top level: cc1: warning: unrecognized command line option "-Wno-unused-but-set-variable" make[3]: *** [cairo-drm-surface.lo] Errore 1 make[3]: Leaving directory `/home/Francesco/git/cairo/src' make[2]: *** [all] Errore 2 make[2]: Leaving directory `/home/Francesco/git/cairo/src' make[1]: *** [all-recursive] Errore 1 make[1]: Leaving directory `/home/Francesco/git/cairo' make: *** [all] Errore 2 i think that the prototype of the function is not included. Anyone can solve?
Don't try compiling the drm backend.
i need the drm backend. However the error appears
The drm has never been released in a non-broken form; you are expected to fix it first.
the libdrm or the backend? The error still appears if I disable the backend during the configure
