Pango crash with cross compilation

[Julien Grossholtz <jg powerlinux fr>]

Hello,

I'm trying to use Clutter on an embedded device, to do so I've cross
compiled Pango and fontconfig. I'm not using X. I've used these options
to cross compile pango :

./configure --prefix=/opt/pango --exec-prefix=/opt/pango --host=
$host_alias --with-x=no


The problem comes when I try to execute a program with some text, I get
a crash :

 ./SimpleText
*** glibc detected *** ./SimpleText: munmap_chunk(): invalid pointer:
0x000827e8 ***
======= Backtrace: =========
/lib/libc.so.6[0x40a57af4]
./SimpleText[0x21a70]
./SimpleText[0xf35c]
./SimpleText(
FcConfigSubstituteWithPat+0x59c)[0xfa5c]
./SimpleText(FcConfigSubstitute+0x30)[0xfdc0]
/opt/pango/lib/libpangocairo-1.0.so.0[0x40211f8c]


I'm able to use fc-match,fc-cache, fc-cat and fc-list, and so to
configure fontconfig. fc-match returns decent answers so I guess it's
working.

The first time I've executed my program it tells this :

(./SimpleText:2682): 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:
  '/opt/pango/etc/pango/pango.modules'
You should create this file by running:
  pango-querymodules > '/opt/pango/etc/pango/pango.modules'

I did it, and it has worked because I've put my libraries in /opt on the
2 systems. But I think that my crash could be related with the content
of  pango.modules on the embedded system :

This is the modules list :

 ls /opt/pango/lib/pango/1.6.0/modules/
pango-arabic-fc.la    pango-arabic-lang.so  pango-hangul-fc.la
pango-hebrew-fc.so  pango-indic-lang.la  pango-khmer-fc.so
pango-thai-fc.la      pango-tibetan-fc.so
pango-arabic-fc.so    pango-basic-fc.la     pango-hangul-fc.so
pango-indic-fc.la   pango-indic-lang.so  pango-syriac-fc.la
pango-thai-fc.so
pango-arabic-lang.la  pango-basic-fc.so     pango-hebrew-fc.la
pango-indic-fc.so   pango-khmer-fc.la     pango-syriac-fc.so
pango-tibetan-fc.la

Maybe these modules are not supposed to be on the embeded system and
comes from the host and so they are causing the crash ?
How can I check that this list of modules is related with my embedded
system and not with the host system ? If they are not I guess I must set
an option to create only the needed modules.

Or maybe I'm doing something else wrong ?
