Hi people
I am trying to migrate an opengl sample that it used to work under the
old (3) version of the sdk, and so far, I am not having much
success...
this is my function for setting up the opengl environment:
boolean initOpenGL()
{
egl = (EGL10) EGLContext.getEGL();
display = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
int[] majorMinor = new int[2];
egl.eglInitialize(display, majorMinor))
int[] numConfigs = new int[1];
egl.eglGetConfigs(display, null, 0, numConfigs);
int configAttributes[] =
{
EGL10.EGL_RED_SIZE, 5, EGL10.EGL_GREEN_SIZE, 6,
EGL10.EGL_BLUE_SIZE, 5,
EGL10.EGL_ALPHA_SIZE, 0,
EGL10.EGL_DEPTH_SIZE, 16,
// EGL11.EGL_STENCIL_SIZE, EGL11.EGL_DONT_CARE, // don't
care about stencils
EGL10.EGL_SURFACE_TYPE, EGL10.EGL_WINDOW_BIT,
EGL10.EGL_NONE
};
EGLConfig eglConfigs[] = new EGLConfig[numConfigs[0]];
egl.eglChooseConfig(display, configAttributes, eglConfigs,
eglConfigs.length, numConfigs);
EGLConfig eglConfig = eglConfigs[0];
glc = egl.eglCreateContext(display, eglConfig,
EGL10.EGL_NO_CONTEXT, null);
gl = (GL10) (glc.getGL());
surface = egl.eglCreateWindowSurface(display, eglConfig, mHolder,
null);
egl.eglMakeCurrent(display, surface, surface, glc);
}
The program crashes when calls "eglCreateWindowSurface()"
The only thing I am not sure about in this function, is the parameter
mHolder, which I got it like this:
class myView extends SurfaceView implements SurfaceHolder.Callback
{
SurfaceHolder mHolder;
public myView(Context context, AttributeSet attrs)
{
super(context, attrs);
mHolder = getHolder();
mHolder.addCallback(this);
mHolder.setType(SurfaceHolder.SURFACE_TYPE_GPU);
}
}
Also, there are two strange things:
- the override methods
surfaceCreated, surfaceDestroyed, and surfaceChanged are never
being called
-in the adb logcat I get the following message after calling
"eglGetDisplay()":
"GLLogger couldn't load <libhgl.so> library (cannot find library)"
does anybody have any idea what I am doing wrong?
pleeeeeeeease!
