HI Manuel,
Thanks for your reply, I’ve tried your method but the application
crash, then I use the gdb to trace the stack, find that libEGL.so.1 call the “
dri2_initialize_x11()”, as you mentioned it seems that EGL trying to use X11
backend, may I try the latest snapshots? the following is the bt print info:
Program received signal SIGSEGV, Segmentation fault.
[Switching to LWP 681]

Hi Jacky,
It looks like EGL is trying to use its X11 backend ; which was the default on
older installs due to the way EGL/Mesa used to be built (FYI, it was changed
in latest snapshots).
You may work around the problem by explicitly calling the EGL Wayland backend :
#include <wayland-egl.h>
struct wl_display *display;
display = wl_display_connect (NULL);
m_display = eglGetDisplay ((EGLNativeDisplayType) display);

Manuel

Hi all,
I came across the issue that executing of function “eglInitialize “
failed, if anyone who knows the solution, please help me, the followings are
the print info and my codes:
eglGetDisplay begin
eglGetDisplay end
eglInitialize begin
libEGL warning: DRI2: xcb_connect failed
libEGL warning: DRI2: xcb_connect failed
libEGL warning: GLX: failed to load GLX
eglInitialize falied
My snippet codes:
printf("eglGetDisplay begin\n");
if ((m_display = eglGetDisplay(EGL_DEFAULT_DISPLAY)) != EGL_NO_DISPLAY)
{
errorLine = __LINE__;
printf("eglGetDisplay falied\n");
return;
}
printf("eglGetDisplay end\n");
printf("eglInitialize begin\n");
if (!eglInitialize(m_display, 0, 0))
{
errorLine = __LINE__;
printf("eglInitialize falied\n");
return;
}
printf("eglInitialize end\n");
Best Regards,
Jacky Ni
