Hi, i am trying to use opengl on Tiny6410. There are two opengl (1.1 and 2.0) examples in the WinCE image. How to write your own application to use opengl ? I have successfully used GLUT on my x86 machine, and have been trying to use GLUTES for Tiny6410 WinCE using Vincent and GLUTES: http://www.zeuscmd.com/tutorials/opengles/02-SettingUpYourEnvironment.php I have done everything in the instruction and wasnt able to run it on my Tiny6410. Problems: 1) glutes_static.lib(glutes_main.obj) : error LNK2019: unresolved external symbol main referenced in function WinMain - i suppose that i havent put glutes_static.lib in the right place, so the linker cant find it 2) In this example: http://www.zeuscmd.com/tutorials/opengles/03-OpenGLWindow.php There is a function called glutInit(&argc, argv); argv is char ** and when i write program for my board ive got int _tmain(int argc, _TCHAR* argv[]) TCHAR - so i cant pass tchar argv to glutInit. What should i do now ? Try to use this Vincent and GLUTES ? I suppose that if there are these opengl examples in WinCE image, there are also files needed for writing opengl applications in the BSP already - and i have to simply include them in my app and use API ? Thanks for any suggestions regards
