snapshot of X window

tree/branch: poky/denzil
commit: 2c3d4f5beee8f57a74244495511b9294df1085ea

With denzil branch, a multilib build for 32bit connman against qemux86-64 with
ipk format could pass build. But when I start the image, the fonts in X window are corrupted. You could check it in attached snapshot.

The configure I use to build the image:
#######
MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"
IMAGE_INSTALL_append = "lib32-connman-gnome"
#######

Dongxiao, can you help Edwin on this bug, since he is busy with other multilib ones?
Comment 2 Dongxiao Xu 2012-04-22 07:50:56 UTC 
When I build the core-image-sato with your config, I met the following error. Did you meet it before?

Sorry for noise, this is related with my wrong configuration.
Comment 4 Edwin Zhai 2012-04-25 05:50:16 UTC 
This bug caused by modules mechanism in pango:

pango utils, pango-querymodules produce a system config file to indicate where to find the modules when 1st boot, like /usr/{lib64|lib}/pango/1.6.0/modules/ for {x86-64|lib32}-pango respectively. 

When installing lib32-pango on sato-image-qemux86-64, lib32 version of pango-querymodules override x86-64 version and produce a system config file with path for lib32 version of modules. Then x86-64 matchbox-desktop failed to open these modules and loaded corrupted fonts.

One possible solution is put the config file under $LIBDIR so different lib use different config file. Another solution is hacking pango's source code to open the modules under $LIBDIR directly without asking system config file.
