gstreamer without X11?

gstreamer without X11?

[Gary Thomas]

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

ERROR: Nothing PROVIDES 'virtual/libx11' (but /home/local/poky-multi/meta/recipes-multimedia/gstreamer/gst-plugins-base_0.10.36.bb DEPENDS on or otherwise requires it)

Missing or unbuildable dependency chain was: ['my-qte-image', 'packagegroup-core-qt4e', 'qwt-e', 'qt4-embedded', 'gst-plugins-base', 'virtual/libx11']

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

Check that gst-plugins-base resolved PACKAGECONFIG hasn't been
explicitly set somewhere (again, use bitbake -e gst-plugins-base).

Not sure exactly what you mean, but this showed nothing as well:
   $ bitbake -e gst-plugins-base | grep PACKAGECONFIG

what do you mean, 'it shows nothing'? it show show 'something'. if x11 is
enabled:

$ bitbake -e gst-plugins-base | grep PACKAGECONFIG
# $PACKAGECONFIG_pn-qemu-native
PACKAGECONFIG_pn-qemu-native="sdl"
# $PACKAGECONFIG [6 operations]
PACKAGECONFIG="x11"

and if it's not:

$ bitbake -e gst-plugins-base | grep PACKAGECONFIG
# $PACKAGECONFIG_pn-qemu-native
PACKAGECONFIG_pn-qemu-native="sdl"
# $PACKAGECONFIG [6 operations]
PACKAGECONFIG=""

nothing? It should show at least assignment of empty value and a lot of
PACKAGECONFIG usages.

Sorry, no, when x11 is missing, I only get this error:

[gthomas@titan imx6_test]$ bitbake -e gst-plugins-base

If I have x11 in DISTRO_FEATURES, I get a full dump and the grep shows something:

[gthomas@titan imx6_test]$ bitbake -e gst-plugins-base | grep PACKAGECONFIG
# $PACKAGECONFIG [7 operations]
PACKAGECONFIG=" pango x11"
[gthomas@titan imx6_test]$

Note this is using Poky master that's about a week old, but I doubt that
anything has changed in this realm.

pango looks suspicious here. it's not there by default. so something seems
to be setting PACKAGECONFIG in your config, and that could be the root
cause of your problem...

Agreed. Don't use grep and you'll see all the assignments and where
they are from.

The error says nothing about pango, is only says that virtual/libx11
is missing.

That said, this was a problem of my own doing :-(  I have this in
gst-plugins-base_0.10.36.bbappend:
   # Enable extra plugins
   PACKAGECONFIG += "pango x11"

Sorry for all the noise.  It's still too bad that bitbake didn't really
help me find this, only spitting out those errors...

Suspicious because it's not a default value in oe-core, so it must be
set by another layer.

This is exactly what bitbake -e is for - if you don't use grep you'll
see all the assignments that are processed and where they come from.
I thought it would be more lenient in the face of errors, but
obviously not in this case.  I wonder if this can be improved.

Yes, that's what I found.

You can duplicate this with off-the-shelf Poky/Yocto.  Just disable x11
in local.conf
   DISTRO_FEATURES_remove = "x11"
Then you'll get this error:
   [gthomas@titan q_test]$ bitbake -e virtual/libx11
   Loading cache: 100% |##################################################################################| ETA:  00:00:00

Should I file a bitbake bug?

I can't see (although I'm no bitbake expert) why -e has to consider
dependencies.  For example, bitbake -e -b
../meta/recipes-multimedia/gstreamer/gst-plugins-base_0.10.36.bb with
x11 removed from DISTRO_FEATURES correctly shows PACKAGECONFIG="".

Filing a bug seems reasonable to me.
