I'm trying to write an SDL/OpenGL ES application, and SDL tells me there is no OpenGL support in the video driver.

Here is the basic test program:

Code:

#include <SDL/SDL.h>
#include <GLES2/gl2.h>

int main (int argc, char** argv) {
    SDL_Init(SDL_INIT_VIDEO);

    SDL_Surface* screen = SDL_SetVideoMode(800, 480, 16, SDL_OPENGL | SDL_FULLSCREEN);
    if (!screen) {
        printf("Error: %s\n", SDL_GetError());
        return 1;
    }
    SDL_Delay(3000);
    SDL_Quit();
}

I can compile it, but when I run it on the device, I get an error saying "No OpenGL support in video driver".

Is there something I'm doing wrong?

you running it on the emulator or actual device ? I dont think the emulator supports OpenGL yet.

I'm running on the device itself.

Are you sure that it's linked against SDL1.3 and not the default SDL1.2?

Yes. Here is the output from ldd:

Code:

$ ldd glestest
        libSDL-1.3.so.0 => /usr/lib/libSDL-1.3.so.0 (0x4000b000)
        libGLESv2.so => /usr/lib/libGLESv2.so (0x45d70000)
        libc.so.6 => /lib/libc.so.6 (0x41028000)
        libm.so.6 => /lib/libm.so.6 (0x41320000)
        libdl.so.2 => /lib/libdl.so.2 (0x412c8000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x41168000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x41150000)
        libIMGegl.so => /usr/lib/libIMGegl.so (0x464d8000)

        /lib/ld-linux.so.3 (0x41000000)

I tried it first with SDL1.2 and got a different error (something about not being able to load libGL.so)
