Re: Pango failure in cross-compiled enviro [solved]

[John Gorkos <jgorkos wildcatwireless net>]

The problem was not in Pango at all, but in the underlying GLIB.  More 
specifically, when I compiled glib, I was forced to preload the configure 
cache with some values, because test programs cannot be run in a 
cross-compile environment.  Here is the snippet of my configure cache (called 
arm.cache, included in ./configure as "--cache-file=arm.cache"):
lib_cv_long_long_format=ll
lf_cv_sane_realloc=yes
glib_cv_stack_grows=yes
glib_cv_uscore=no
ac_cv_func_posix_getpwuid_r=yes
ac_cv_func_getpwuid_r=yes
glib_cv_has__inline__=yes
glib_cv_has__inline=yes
glib_cv_hasinline=yes
glib_cv_sane_realloc=yes
glib_cv_va_copy=yes
glib_cv___va_copy=yes
glib_cv_va_val_copy=yes
glib_cv_sizeof_gmutex=24
glib_cv_byte_contents_gmutex=no

Not all are needed by glib, but I use the same pre-seed cache for several 
projects.  In my case, I guessed incorrectly at the values for 
glib_cv_stack_grows and glib_cv_uscore.  I ran a ./configure on the native 
arm box, got the correct values, put them in my pre-cache file, and then 
rebuilt GLIB, all of pango's pre-requisites, and pango itself.  I now get the 
expected output from pango-querymodules:
