Deep dive into opengl es: I patched the Atari800 emulator bug on RPi - the bug was located in the fragment shader code. The knowledge gained doing this is priceless.
The patched emulator can be found on my github.

Atari800 emultor code is pure C. Compiles to series of .o - a good candidate to move to Ultibo

The top level Makefile seems to just call the one in each folder, maybe try going into each folder and running make manually to narrow down which one gives the error.

Otherwise a VirtualBox or similar VM with a reasonably common Linux flavor installed will be invaluable, there are many projects whose authors never try building under anything but Linux so you can avoid a lot of messing with details by just having a Linux VM available.

Or maybe use Stretch on a Raspberry Pi?

Been spending some time with normal Laz/FPC and found GLScene.
There is a few links, lots from the old Delphi coder world.
http://glscene.sourceforge.net/wikka/links.htm

I did actually managed to get the Castle Game Engine to sort of install on a PC this week again.
Some demos worked, others I have no clue why they did not compile.
I am not good enough with Laz/FPC on PC's to debug it :oops:

Been looking at Android code too as that is pure OpenGLES.
But I have been coming around to the conclusion the OpenGLES examples provided with Ultibo ARE the best place to start.

At the moment I have been coming at it from many directions.
Bottom up with Baremetal with #$%, Peter Lemon, bzt etc
Top down with PC's and Gentoo64 OpenGL. Sideways with Android etc

I have now come to the conclusion I need to setup a Pi as a Laptop? portable development system and just start coding.
I started this post 1 and 1/2 years ago, back then it was just an idea.
Over that time I now know it can be done (even by me) and to a much higher standard than even I expected.
I now wonder why no one has done a Pi specific game?

Anyway, the Xmas break will allow me to finish the kid's scratch built RetroPie Console (hint, buy a kit instead).
Perhaps one day he will write Ultibo games for it?

For inspiration or just ideas.

It is interesting that people now think it is time for a new game magazine again.
