[Buildroot] [PATCH v3 2/2] qt: add powervr and opengl

[Sundareson, Prabindh]

Hello Spenser,

Thinking more on the above - Is it not possible to pick up the pvr2d.h and wsegl.h from the version of Graphics package used for building Qt itself ? Why does this need to be included in the patch, duplicating the file already existing in the staging area ?

That will resolve the issue of mismatches once and for all.

regards,
Prabu

Ahh, this is something I missed while porting the patch. I'll have to look at this some more, these should be from the latest version.  I'll try to get qt to pick these up from $(STAGING_DIR)/usr/include .

This will be fixed.  I'm only planning to support using the TI Graphics from within Buildroot (i.e. patch 1 of this series.)

There will be a rev 4 with the fix described above.

Thanks,
Spenser
