I'm trying to run the following code on the Evalution kit "8MMINILPD4-EVK" (image "LF_v5.10.72-2.2.0_images_IMX8MMEVK").
#include <stdio.h>
#include <X11/Xlib.h>
#include <EGL/egl.h>
int main(int argc, char *argv[])
{
Display *xdisplay = XOpenDisplay(0);
if(!xdisplay){
printf("XOpenDisplay err\n");
return 1;
}
EGLDisplay edisplay = eglGetDisplay(xdisplay);
if( edisplay == EGL_NO_DISPLAY ){
printf("eglGetDisplay err\n");
return 1;
}
EGLint m_major_version, m_minor_version;
EGLBoolean ok = eglInitialize(edisplay, &m_major_version, &m_minor_version);
if( !ok ){
printf("eglInitialize err\n");
return 1;
}
printf("succesful!, ver: %d.%d\n", m_major_version,m_minor_version);
return 0;
}
compile:
g++ main.cpp -g -lX11 -lEGL -o eglinfo
but on eglInitialize progmamm hang:
root@imx8mmevk:/tmp# DISPLAY=:0 ./eglinfo
Segmentation fault
backtrace:
