Android device - C++ OpenGL 2: eglCreateWindowSurface invalid
- by ThreaderSlash
I am trying to debug and run OGLES on Native C++ in my Android device in order to implement a native 3D game for mobile smart phones. The point is that I got an error and see no reason for that. Here is the line from the code that the debugger complains:
mSurface = eglCreateWindowSurface(mDisplay,
lConfig, mApplication->window, NULL);
And this is the error message:
Invalid arguments ' Candidates are:
void * eglCreateWindowSurface(void *, void *,
unsigned long int, const int *) '
--x--
Here is the declaration:
android_app* mApplication;
EGLDisplay mDisplay;
EGLint lFormat, lNumConfigs, lErrorResult;
EGLConfig lConfig;
// Defines display requirements. 16bits mode here.
const EGLint lAttributes[] = {
EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
EGL_BLUE_SIZE, 5, EGL_GREEN_SIZE, 6, EGL_RED_SIZE, 5,
EGL_SURFACE_TYPE, EGL_WINDOW_BIT, EGL_RENDER_BUFFER, EGL_BACK_BUFFER,
EGL_NONE
};
// Retrieves a display connection and initializes it.
packt_Log_debug("Connecting to the display.");
mDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);
if (mDisplay == EGL_NO_DISPLAY) goto ERROR;
if (!eglInitialize(mDisplay, NULL, NULL)) goto ERROR;
// Selects the first OpenGL configuration found.
packt_Log_debug("Selecting a display config.");
if(!eglChooseConfig(mDisplay, lAttributes, &lConfig, 1,
&lNumConfigs) || (lNumConfigs <= 0)) goto ERROR;
// Reconfigures the Android window with the EGL format.
packt_Log_debug("Configuring window format.");
if (!eglGetConfigAttrib(mDisplay, lConfig,
EGL_NATIVE_VISUAL_ID, &lFormat)) goto ERROR;
ANativeWindow_setBuffersGeometry(mApplication->window, 0, 0, lFormat);
// Creates the display surface.
packt_Log_debug("Initializing the display.");
mSurface = eglCreateWindowSurface(mDisplay, lConfig, mApplication->window, NULL);
--x--
Hope someone here can shed some light on it.
