Simple, really. What version of avr-gcc do the developers use? I ask because Arch Linux upgrades packages really fast, and I think my latest update has broken MultiWii in some form or another. I saw in the .cpp/.h thread something about 4.5? Also, has anyone else had problems with newer versions of avr-gcc? I'm running 4.8

Ok, thanks. For reference, 1.0.5 uses anywhere from 2.4 to 2.8, according to this

Builds fine with avr-gcc 4.8.2 and 4.9.0 on Arch for me (and I flew the 4.8.2 build yesterday). Multiwii 2.3 with a patch for PROGMEM in GPS.cpp, which I posted about some time ago.

I added that patch and it compiles. I'm still having PWM issues, though, so I'm going to try compiling with the stock arduino avr-gcc in a ubuntu vbox

Everything works after compiling with stock arduino 1.0.5! I think the FFIMUv2 board files never got updated to work properly with newer avr-gcc versions, because my status LEDs also weren't working.
