Bug 3788

This issue is caused by pango.
When booting up image with nographic mode, I can get the following error messages in console:
#############
(matchbox-panel:417): Pango-CRITICAL **: No modules found:
No builtin or dynamically loaded modules were found.
PangoFc will not work correctly.
This probably means there was an error in the creation of:
  '/etc/pango/pango.modules'
You should create this file by running:
  pango-querymodules > '/etc/pango/pango.modules'

The /etc/pango/pango.modules file exists but is empty:

I run the following command to re-generate this file:

After reboot, this issue disappears.

I took the 20130125-1 core-image-sato powerpc nightly from autobuilder and the image booted just fine.

I also compiled core-image-sato from latest (f0e02dc132c301c0a33a3a8cecddc867b1f0a70e) and it also booted just fine.

Since there is no log provided, I cannot really tell what happened...

also no such error when build the qemuppc sato-sdk image (git commit: 8d6e55bf2192524bda84138b5356a2791adbbe61), and copy "/etc/pango/pango.modules" from the image to the sato-sdk images of nightly build 20130122-2 and reboot , the desktop display normally.below the contents of the file "/etc/pango/pango.modules" :

The 20130125-1 build is against master_under_test branch:
#################
meta-yocto        = "stage/master_under_test:e3914a59b7a240861911153bd761b333b638a4a1"
meta-qt3          = "master:06e2fe600de962cdba53c23de1207501439a9c9f"
meta-yocto-bsp    = "stage/master_under_test:e3914a59b7a240861911153bd761b333b638a4a1"
##################

The 20130125-2 build is against the newer master branch:
##################
meta-yocto        = "master:a1ac22a73c226e268bea90eaa043b3da4695d577"
meta-qt3          = "master:06e2fe600de962cdba53c23de1207501439a9c9f"
meta-yocto-bsp    = "master:a1ac22a73c226e268bea90eaa043b3da4695d577"
##################

This issue still exists in this build. But if we build the image in local with a clean build, there is no this issue.

Is it caused by sstate file in autobuilder ?

I'm sorry I gave the wrong information. I create the qemuppc image in local again with a clean build, this issue also exists. My host is ubuntu 11.10 x86-64. The git rev is: 8d6e55bf2192524bda84138b5356a2791adbbe61

Can you attach the log.do_rootfs?

Created attachment 1028 [details]
log.do_rootfs

I compiled it again two times, from scratch. Once I used the sstate from a build server and once without any sstate cache. It worked fine both times. Could it be related to the distribution used? Here is the build configuration I used:

Build Configuration:
BB_VERSION        = "1.17.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "Ubuntu-12.04"
TARGET_SYS        = "powerpc-poky-linux"
MACHINE           = "qemuppc"
DISTRO            = "poky"
DISTRO_VERSION    = "1.3+snapshot-20130129"
TUNE_FEATURES     = "m32 fpu-hard ppc603e"
TARGET_FPU        = ""
meta
meta-yocto
meta-yocto-bsp    = "master:cfb082961a6c9ac3d65738031c4071210529cd07"

I also looked in the log.do_rootfs and saw that qemu-ppc segfaults... It would be interesting to execute the command sepparately and see what happens. But before doing it, set D to the appropriate path and make sure you go to the native sysroot. Here's what, I'm guessing the paths here, you should run:

$ export D=/buildarea2/yzhao1/poky-build/build-world/tmp/work/qemuppc-poky-linux/core-image-sato/1.0-r0/rootfs/
$ cd /buildarea2/yzhao1/poky-build/build-world/tmp/sysroots/x86_64-linux
$ ./usr/bin/qemu-ppc $D$(readelf -l $D/usr/bin/gtk-query-immodules-$maj_ver.0| grep "Requesting program interpreter"|sed -e 's/^.*\[.*: \(.*\)\]/\1/') --library-path $D/lib:$D/usr/lib $D/usr/bin/gtk-query-immodules-$maj_ver.0 $IMFILES > $D/etc/gtk-$maj_ver.0/gtk.immodules
