cross compile for avr atmega (arduino)

Hello i'm try cross compile for avr ...

how chage this check?

Well, Atmen AVR is not a target we support out of the box, so you might need to provide more details on the new target you made to help figure this out? Also, the host type for libgambc might need to be set in libraries/libgambc/make.sh just like we do for win32 for example: libraries/libgambc/make.sh#L22

Do you think it is interesting to compile for the avr platform?

[mgorges]

If I look at gambit/gambit#485 this still seems to be work in progress to even get Gambit to cross-compile let alone any other library? As for interest, personally: no - we use Raspberry Pi or BeagleBone black for small embedded systems, but that doesn't mean others might not find this interesting. However, I don't have a device to test with and as long as Gambit won't compile I don't think we can quickly add this as a supported platform?
