This is by no means an official answer, but when I work on powerd and the openclipart scope example I just use a pbuilder. I usually use pbuilder-scripts (apt-get install pbuilder-scripts), which makes setting up a pbuilder easier. I don't see any online docs for it from a brief search, so here's my 10 second overview:
pcreate -a armhf -d saucy saucy-armhf Add any PPAs that you need when the terminal opens up. I have the phablet-team and daily-build-next in mine. Then enter the pbuilder shell, I think it will bind mount ~/Projects by default, so I usually put my code there. (You can add extra mounts in ~/.pbuilderrc) ptest -p saucy-armhf Once at this shell, install whatever build-deps you need, for example: apt-get build-dep powerd And compile away... When it's time to test, I then install openssh-client in my pbuilder so I can scp binaries to the phone. (Note: you can also just add openssh-client to the EXTRAPACKAGES= line in your ~/.pbuilderrc). Once you're done, just close the terminal and it will set your pbuilder back to a pristine state. There's a full howto on pbuilder here, but it does not cover the scripts: https://wiki.ubuntu.com/PbuilderHowto On Mon, Jul 15, 2013 at 5:59 AM, Josh Leverette <[email protected]> wrote: > If the size of the program makes compiling the code on the device > practical, then that would be my personally recommended place to compile > it.
