Thanks, applied, after doing a bunch of changes:

[Thomas:
- Remove changelog from the commit log.
- Rename init script to S99iiod instead of S99iiod.sh
- Remove "status" command from init script, and implement "restart" instead.
- Add dependency on thread support in toolchain.
- Fixup indentation in the .mk file.
- Fixup wrapping in the Config.in help text.]

Also, if you don't have any /sys/bus/iio/devices directory, the iiod daemon doesn't start, with a mysterious "Unable to create context" message, which only appears if you start iiod manually (not from the init script). Maybe it should be improved a bit: make sure to have a proper error message, and make sure it gets shown when iiod is started from the init script.

Thanks!

Thomas

PATCH v5 1/1 libiio: new package

Dear Thomas,

Thanks for merging this patch - and thanks for the extra work.

I see you added a dependency on thread support in the toolchain, is it because it breaks some builds if not set?
The library in itself will work just fine on a system without threads, only the IIO Daemon requires threads, that's why I'm asking.

Regards,

Paul Cercueil

I honestly don't remember. You can try building with the base config
http://autobuild.buildroot.org/toolchains/configs/br-arm-full-nothread.config
and see what breaks (of course after removing the dependency on threads).

Thanks,

Thomas
