Different EGL libraries will do different things here, and in -particular glvnd will do something different than Mesa. Since we do have -an API that allows us to explicitly type the display, use it. - -The explicit call to eglGetProcAddress is working around a bug in -libepoxy 1.3, which does not understand the EGL concept of client -extensions. Since it does not, the normal epoxy resolver for -eglGetPlatformDisplayEXT would not find any provider for that entry -point, and crash when you attempted to call it. - -Signed-off-by: Adam Jackson <ajax@redhat.com> ---- - gdk/wayland/gdkglcontext-wayland.c | 37 ++++++++++++++++++++++++++++++++++++- - gtk/inspector/general.c | 32 +++++++++++++++++++++++++++++++- - 2 files changed, 67 insertions(+), 2 deletions(-) - -diff --git a/gdk/wayland/gdkglcontext-wayland.c b/gdk/wayland/gdkglcontext-wayland.c -index ae1354e..6573688 100644 ---- a/gdk/wayland/gdkglcontext-wayland.c -+++ b/gdk/wayland/gdkglcontext-wayland.c -@@ -274,6 +274,40 @@ gdk_wayland_gl_context_init (GdkWaylandGLContext *self) - { - } - -+static EGLDisplay -+gdk_wayland_get_display (GdkWaylandDisplay *display_wayland) -+{ -+ EGLDisplay dpy = NULL; -+ -+ if (epoxy_has_egl_extension (NULL, "EGL_KHR_platform_base")) -+ { -+ PFNEGLGETPLATFORMDISPLAYPROC getPlatformDisplay = -+ (void *) eglGetProcAddress ("eglGetPlatformDisplay"); -+ -+ if (getPlatformDisplay) -+ dpy = getPlatformDisplay (EGL_PLATFORM_WAYLAND_EXT, -+ display_wayland->wl_display, -+ NULL); -+ if (dpy) -+ return dpy; -+ } -+ -+ if (epoxy_has_egl_extension (NULL, "EGL_EXT_platform_base")) -+ { -+ PFNEGLGETPLATFORMDISPLAYEXTPROC getPlatformDisplay = -+ (void *) eglGetProcAddress ("eglGetPlatformDisplayEXT"); -+ -+ if (getPlatformDisplay) -+ dpy = getPlatformDisplay (EGL_PLATFORM_WAYLAND_EXT, -+ display_wayland->wl_display, -+ NULL); -+ if (dpy) -+ return dpy; -+ } -+ -+ return eglGetDisplay ((EGLNativeDisplayType) display_wayland->wl_display); -+} -+ - gboolean - gdk_wayland_display_init_gl (GdkDisplay *display) - { -@@ -284,7 +318,8 @@ gdk_wayland_display_init_gl (GdkDisplay *display) - if (display_wayland->have_egl) - return TRUE; - -- dpy = eglGetDisplay ((EGLNativeDisplayType)display_wayland->wl_display); -+ dpy = gdk_wayland_get_display (display_wayland); -+ - if (dpy == NULL) - return FALSE; - -diff --git a/gtk/inspector/general.c b/gtk/inspector/general.c -index 77d0a76..f32f7fe 100644 ---- a/gtk/inspector/general.c -+++ b/gtk/inspector/general.c -@@ -214,6 +214,36 @@ append_egl_extension_row (GtkInspectorGeneral *gen, - { - add_check_row (gen, GTK_LIST_BOX (gen->priv->gl_box), ext, epoxy_has_egl_extension (dpy, ext), 0); - } -+ -+static EGLDisplay -+wayland_get_display (struct wl_display *wl_dpy) -+{ -+ EGLDisplay dpy = NULL; -+ -+ if (epoxy_has_egl_extension (NULL, "EGL_KHR_platform_base")) -+ { -+ PFNEGLGETPLATFORMDISPLAYPROC getPlatformDisplay = -+ (void *) eglGetProcAddress ("eglGetPlatformDisplay"); -+ -+ if (getPlatformDisplay) -+ dpy = getPlatformDisplay (EGL_PLATFORM_WAYLAND_EXT, wl_dpy, NULL); -+ if (dpy) -+ return dpy; -+ } -+ -+ if (epoxy_has_egl_extension (NULL, "EGL_EXT_platform_base")) -+ { -+ PFNEGLGETPLATFORMDISPLAYEXTPROC getPlatformDisplay = -+ (void *) eglGetProcAddress ("eglGetPlatformDisplayEXT"); -+ -+ if (getPlatformDisplay) -+ dpy = getPlatformDisplay (EGL_PLATFORM_WAYLAND_EXT, wl_dpy, NULL); -+ if (dpy) -+ return dpy; -+ } -+ -+ return eglGetDisplay ((EGLNativeDisplayType) wl_dpy); -+} - #endif - - -@@ -254,7 +284,7 @@ init_gl (GtkInspectorGeneral *gen) - EGLint major, minor; - gchar *version; - -- dpy = eglGetDisplay ((EGLNativeDisplayType)gdk_wayland_display_get_wl_display (display)); -+ dpy = wayland_get_display (gdk_wayland_display_get_wl_display (display)); - - if (!eglInitialize (dpy, &major, &minor)) - return; --- -2.9.3 - |
