Hi,
I've just released a guide to get my free, open-source, cross-platform, visual programming system Fugio up and running on a Raspberry Pi.
http://wiki.bigfug.com/view/Cross_Compi ... spberry_Pi
Fugio is a visual programming system, somewhat like Max MSP, Quartz Composer, vvvv, etc, with an emphasis on providing a free, open, and sustainable platform for creative projects (I'm an artist and I wrote Fugio to power my various installations and performances) and sharing knowledge.
It's a highly modular system and supports a wide range of technologies, including OpenGL graphics, MIDI, Open Sound Control (OSC), audio input/output and processing, Lua scripting, and easy networking, with many more in development.
The guide also covers setting up a VirtualBox Linux development machine (if you need it), cross-compiling Qt 5.7, and building Fugio from source.
