arm architecture support example

[Aiken Qi]

Luca,
Suggest you use docker on RPi snappy, and use Ubuntu core docker image for armhf. It's quite straight forward for native compile.

Thank you Alexander,
I will try to setup a qemu instance over armv7.. if feasibile.. and try to build from there.

Best, Luca

Hi,



cross compilation of nodejs with snapcraft is tricky. If you manually

build/assemble your stuff you can try the instructions on cross

compiling you can find on the web, but for snapcraft the best way is

to go for native building on your pi2...



For snappy 15.04 you can get a developer ubuntu experience by using

lxd. For snappy 16.04 you can "sudo snappy enable-classic" mode and

then switch into a convenient ubuntu shell where you can apt-get

install etc. with "sudo snappy shell classic"



My etherpad-lite snap builds nicely that way. See
