    I'm trying to build QTE with a distribution that does not include x11.
    However, I'm getting this error:

    I don't understand why this happens though as the gst-plugins-base
    recipe uses PKGCONFIG to control this:
       PACKAGECONFIG ??= "${@base_contains('DISTRO___FEATURES', 'x11', 'x11', '', 
d)}"
       PACKAGECONFIG[x11] = "--enable-x --enable-xvideo,--disable-x 
--disable-xvideo,virtual/__libx11 libxv libsm libice"

    How can the depencency on virtual/libx11 still be there if DISTRO_FEATURES 
does not contain x11?


obvious question... are you sure DISTRO_FEATURES does not contain x11? did you 
define you own distro config? it is there by default, so unless you did 
something to remove it, it
will be there.

you can display the value of the variable with

bitbake -e gst-plugins-base | grep ^DISTRO_FEATURES

you can check the value of PACKAGECONFIG as well to get more information.

Yes, I explicitly removed this in local.conf:

[gthomas@titan imx6_test]$ tail -n5 conf/local.conf

# Enable local PR server - edit this to use a shared server
PRSERV_HOST = "localhost:0"

DISTRO_FEATURES_remove = "x11 wayland"

[gthomas@titan imx6_test]$ bitbake -e gst-plugins-base | grep ^DISTRO_FEATURES
 ... nothing
