Image Processing with OpenGL and Shaders

[Nagilo]

I found this really nice article http://www.linuxjournal.com/content/ima ... nd-shaders but wasn't able to compile it on the rPi. Did anyone ever used this sample?

That's the error I got for make

cc -c -Wformat=2 -Wall -Wswitch-default -Wswitch-enum -Wunused-parameter -Wextra -Wshadow -Wbad-function-cast -Wsign-compare -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wunreachable-code -ffast-math -march=pentium3 -g -DGL_CHECK callbacks.c
cc1: error: bad value (pentium3) for -march switch
make: *** [callbacks.o] Error 1

The error is pretty self explanatory - you are compiling for a Pentium architecture. The Raspi is an ARM architecture.

Also bear in mind that Raspberry Pi does not support the same OpenGL as your desktop computer. Like most embedded systems, it supports OpenGL ES, which is a stripped-down version of OpenGL. You need to modify OpenGL code (including shaders) to make it work on Pi.
