<br>
cross compilation of nodejs with snapcraft is tricky. If you manually<br>
build/assemble your stuff you can try the instructions on cross<br>
compiling you can find on the web, but for snapcraft the best way is<br>
to go for native building on your pi2...<br>
<br>
For snappy 15.04 you can get a developer ubuntu experience by using<br>
lxd. For snappy 16.04 you can "sudo snappy enable-classic" mode and<br>
then switch into a convenient ubuntu shell where you can apt-get<br>
install etc. with "sudo snappy shell classic"<br>
<br>
My etherpad-lite snap builds nicely that way. See<br>
