I've been trying to make a library to use GLES 1.x but I can't even seem to get act one right - I cannot even open a GL display. Here is the code:
On Linux X86, I get:
...and on the Pandora:
I haven't the faintest idea what is wrong on the Pandora, but I assume the issue on the X86 has to do with the GLES simulation libraries. Any ideas?
Code:
static bool InitEGL(bool FSAA)
{
nEGL_Display = eglGetDisplay((NativeDisplayType)nX11_Display);
if (EGL_NO_DISPLAY==nEGL_Display)
{
errorf("WARNING: eglGetDisplay((NativeDisplayType)nX11_Display) failed.\n"\

nEGL_Display = eglGetDisplay(EGL_DEFAULT_DISPLAY);
if (EGL_NO_DISPLAY==nEGL_Display)
{
errorf("Error: eglGetDisplay() failed.\n");
Shutdown();
return false;
}
}
EGLint iMajorVersion, iMinorVersion;
if (!eglInitialize(nEGL_Display, &iMajorVersion, &iMinorVersion))

}On Linux X86, I get:

There are literally no configurations available.
Unable to initialize EGL...and on the Pandora:
Code:
WARNING: eglGetDisplay((NativeDisplayType)nX11_Display) failed (Success!).
Attempting eglGetDisplay(EGL_DEFAULT_DISPLAY)
Error: eglInitialize() failed (BAD ALLOC).
server does not have extension for "r rate" option
Unable to initialize EGLI haven't the faintest idea what is wrong on the Pandora, but I assume the issue on the X86 has to do with the GLES simulation libraries. Any ideas?
