Forum Topic - No GL_IMG/GL_ARB extensions found in OpenGL 1.4: (4 Items)
   
No GL_IMG/GL_ARB extensions found in OpenGL 1.4  
Hi All,

We have an MTP development board (OMAP3530) with QNX 6.4.1, and the gears demo states there's OpenGL 1.4 on it.
Are the GL_IMG and GL_ARB extensions supported here (or do they exist at all in 1.4)?
Or should we set anything to get them work?

By default, no environment variables are set (should we set any?), but the demo runs well (without these extensions...):

# gles1-kd-gears -verbose
EGL1.4
found 1 config(s)
EGL_CONFIG_ID = 32
EGL_RED_SIZE = 5
EGL_GREEN_SIZE = 6
EGL_BLUE_SIZE = 5
EGL_ALPHA_SIZE = 0
EGL_DEPTH_SIZE = 16
EGL_LEVEL = 0
EGL_NATIVE_RENDERABLE = EGL_FALSE
EGL_NATIVE_VISUAL_TYPE = 4880
EGL_RENDERABLE_TYPE = 0x0001
EGL_SURFACE_TYPE = 0x0487
EGL_TRANSPARENT_TYPE = EGL_NONE
GL_RENDERER = Software Rasterizer
GL_VERSION = OpenGL ES-CM 1.0
GL_VENDOR = QNX Software Systems
GL_EXTENSIONS = GL_OES_compressed_paletted_texture GL_OES_vertex_buffer_object GL_OES_query_matrix GL_OES_read_format


Thanks in advance.
Regards,
Marton

Hi Marton,

Maybe someone else will clarify further, but ...

It actually says:
OpenGL ES-CM 1.0

the EGL interface is indicated as 1.4

Kind Regards,
-Derek

Re: No GL_IMG/GL_ARB extensions found in OpenGL 1.4  
Right now, you are using the 'all-software' QNX OpenGL ES 1.0 driver with an EGL 1.4. When the ImgTech driver is 
released for OMAP3530, it will support all IMG extensions and some OES extensions. I don't think the ImgTech driver 
supports any ARB extension on OpenGL ES.

Note that the extensions supported vary between the OpenGL ES 1.1 and the OpenGL ES 2.0 APIs that are both supported by 
the ImgTech driver.

If there is an extension in particular you plan on using, we should be able to tell you if the driver will support it.

Hi Derek,

Thanks for the clarification, it seems we got confused on the versions, but now this fact answers all our questions.
So now the next step is to purchase the necessary libs :)

Thanks & regards,
Marton
