Should be 'ifeq ($(BR2_PACKAGE_LIBGUDEV),y)', in think, since all we need is 
to have libgudev built before this package, regardless of systemd. With this 
change the comment becomes redundant. The comment in Config.in should be 
enough.

we need libgudev only if we are going to use systemd. Otherwise it will
be provided by eudev.

Of course we could use ifeq ($(BR2_PACKAGE_LIBGUDEV),y) here, but, for
consistency with Config.in, I use ifeq ($(BR2_PACKAGE_SYSTEMD),y)
instead. See for instance the udisks package.

Regards,

Vincent.

Applied to next, with a few changes:

    [Thomas:
     - use BR2_INIT_SYSTEMD instead of BR2_PACKAGE_SYSTEMD for the
       libgudev handling. This is consistent with what we do in libmbim,
       modem-manager and network-manager. Only udisks is diverging from
       this by using BR2_PACKAGE_SYSTEMD.
     - Fix the license info: it is GPLv3 *or* BSD-3c *or* the specific
       HIDAPI license. Added LICENSE-orig.txt to LICENSE_FILES.]

Thanks,

Thomas

I think this is wrong. First, consistency with Config.in calls for using 
BR2_PACKAGE_LIBGUDEV like we do with all other selects. But more importantly, 
IMO, we only use the <pkg>_DEPENDENCIES variable to set the build order which 
is conceptually independent of the underlying reason we need this dependency, 
systemd in this case. I think that all the other packages that Thomas 
mentioned should also test for BR2_PACKAGE_LIBGUDEV when setting 
<pkg>_DEPENDENCIES.

I am not as clear-cut as you are on what is the correct thing to do
here, but your reasoning seems reasonable to me. So we need to align
the existing packages to do this, and also to use BR2_INIT_SYSTEMD in
Config.in (udisks uses BR2_PACKAGE_SYSTEMD). Will you send some patches
or should I do so?

Thanks,

Thomas

I'll send the patches later. Would you like one patch per package, or a single 
patch based on next?

I think a single patch is good enough, the number of affected packages
is pretty small.

Hi Vicente,

This looks ok to me.

For embedded, it would be nice to be able to build with only one 
back-end (hidraw or libusb), but hidapi doesn't currently support 
building that way. One day I'll get there.

Thanks for doing this!

Alan.
