Rahul, All,

On 2016-07-04 18:16 +0530, Rahul Bedarkar spake thusly:
> aserver tool is licensed under GPLv2+. It is built if 'shm' pcm plugin
> is enabled. So, specify its license conditionally when it is enabled.

We prefer positive logic, which you can achieve with something like:

    ifeq ($(filter shm,$($(call qstrip,$(BR2_PACKAGE_ALSA_LIB_PCM_PLUGINS)))),shm)

> +ALSA_LIB_HAS_SHM_PLUGIN = y

Ditto.

As for libuci, this creates an ill-formatted string. Use the same trick
to fix it. ;-)
