Debian's version of OpenGL is called Mesa and it supports normal

for hardware-acceleration of OpenGLES on ARM, no free drivers in
Debian yet. Some reverse engineering projects and free drivers exist
outside of Debian though:

Well, I can temporarily install the binary blobs, can't I? These ones: http://linux-sunxi.org/Binary_drivers . They even have a rebuilt package specifically for debian. I know I'm on my own re stability of that. But then eventually, as I hope, LIMA will mature and make it into Debian.

You can install OpenGLES (libgles1-mesa-dev or libgles2-mesa-dev) on
your standard Debian amd64 PC system, try to build your code and
change it until it doesn't fail.

Aha - thanks! It's actually a Debian i686 system but it would fit even better (current arm architectures are 32 bit).

This will be hardware-accelerated and
be easier than messing around with cross-compilers.

Here are some guides for converting OpenGL code to OpenGLES, any
issues you encounter should be fixable by using a search engine
though.

Thanks a LOT. Exactly what I needed. Looks like I can give a lot of trying to the port attempt before deciding on hardware.
