Hi all, I made mesa with following configuration $ ./autogen.sh --prefix=$WLD --enable-gles2 --disable-gallium-egl --enable-shared-glapi --with-egl-platforms=wayland,drm and test wayland applications with $ ./compositor but get following errors libEGL debug: EGL search path is /home/joshua/install/lib/egl libEGL debug: added /home/joshua/install/lib/egl/egl_gallium.so to module array libEGL debug: added egl_glx to module array libEGL debug: dlopen(/home/joshua/install/lib/egl/egl_gallium.so) libEGL info: use wayland for display 0x9a6a128 libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize(no usable display) libEGL info: use wayland for display 0x9a6a128 libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize(no usable display) libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize failed to initialize display libEGL info: use DRM for display 0x5 libEGL debug: searching for pipe module i915 libEGL debug: loaded /home/joshua/install/lib/egl/pipe_i915.so get chip id failed: -1 [13] param: 4, val: 0 libEGL debug: failed to create DRM screen libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize(no usable display) libEGL info: use DRM for display 0x5 get chip id failed: -1 [13] param: 4, val: 0 libEGL debug: failed to create DRM screen libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize(no usable display) libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglInitialize failed to initialize display failed to initialize egl failed to create compositor How to fix these errors?
