Android emulator support for OpenGL ES 3.1

[Rishi Ranjan]

Hi,

    I read the host side emugen README to get the Open GL ES support on Android emulator. I understand that I have to get the APIs from gl31.h and add it to host/libs/GLESv2_dec/gl2.in. Is there a way to automatically read this from the header and insert it to host/libs/GLESv2_dec//gl2.in so that there are not errors. 

Also is there are documentation to write translation for to OpenGL 4.5 instead of 2.0? 

Thanks,

Rishi

I was able to find frameworks/native/opengl/libs/tools/genfiles which generates .in files from header but not sure how to generate the .attribs file automatically.

Unfortunately, it's generally not possible to generate the .attrib files from the headers, because the information they describe is part of the specification, but not the C function declarations (i.e. are buffers input, output or both, are some pointers optional and can be NULL, etc...)

In other words, these have to be written by hand.

I don't think there is any documentation. Keep in mind that we're seeing issues related to bugs in the host OpenGL drivers, especially on Windows, which is why we're looking at using ANGLE on this platform to replace the translator libraries, i.e. not using any desktop GL at all.

We're still unsure what's the ES 3.0/3.1 story will be in that context.
