bitbake meta-toolchain-qt5失败，尽管功能已删除，但不能满足x11

Question

Building Qt5 toolchain for Raspberry Pi2 Qt apps using Yocto fido See this tutorial . My build machine is NUC with Debian 7.8.

Succeeded to build my image perfectly, but getting error while building my toolchain.

my local.conf , I removed x11 feature

MACHINE = "raspberrypi2"
LICENSE_FLAGS_WHITELIST="commercial license"

DISTRO = "poky"
DL_DIR = "${TOPDIR}/../dl"
PACKAGE_CLASSES = "package_ipk"
DISTRO_FEATURES_remove = "x11 wayland"   <========= 
# Set Rpi GPU Memory to 128MB
GPU_MEM = "128"

my bblayers.conf

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly

LCONF_VERSION = "6"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
    ${TOPDIR}/../poky/meta-embarcados \
    ${TOPDIR}/../poky/meta-embarcados/meta-rpi \
    ${TOPDIR}/../poky/meta-qt5 \
    ${TOPDIR}/../poky/meta-raspberrypi \
    ${TOPDIR}/../poky/meta-openembedded/meta-oe \
    ${TOPDIR}/../poky/meta-openembedded/meta-ruby \
    ${TOPDIR}/../poky/meta \
    ${TOPDIR}/../poky/meta-yocto \
  "

I have tried from scratch by removing my build/tmp folder to no avail, I am still getting the x11 dependency issue although it's a removed feature in my local.conf .

Any pointers on how to resolve this? why would it still try to compile x11 feature when removed?

(Votes down are Ok, but a comment explaining why you are voting down is better. It's not like I am not trying hard on my side to resolve this critical issue on a Sunday! There is definitely some trolls in the StackExchange community)

Libraries on build machine

This look to be the problem, the installed version is 1.5.0-1+deb7u2 where it requires >=1.6.2 . That doesn't answer my question, but that's a hint.

Upgraded to Debian 8.1 but problem persists

although libx11-6 , libxau6 , libxdmcp6 satisfy the version requirements, one library doesn't, and I can't install >=1.11 (I think), this is the latest libxcb1 on Jessie that I can get.

definitely something in the packagegroup-qt5-toolchain-target

Answer 1

This sounds similar to the experience I had where I built for X11 then subsequently turned it off with DISTRO_FEATURES_remove = "x11" .

As far as I could see there was still a dependency on X11 somewhere in the license manifest , from what I recall there was a header file used Xauth in pango/cairo that's stubbed out without X11 .

The problem went away when I built for a different MACHINE , so I would suggest launching a completely fresh build without X11 after clearing your SSTATE_CACHE .
