some cross compile problems

[pencil 磊]

We are working on porting pidgin to qtopia. 
We have finished cross-compile some libraries needed by libpurple 
libraries, They are:
glib, gnutils(for cross compile gnutils we need libtansn, libgpg-error, 
libgcrypt), libxml2. we also cross compile meanwhile for sametime protocol. 

When we cross compile libpurple, it is also ok, and we get the libpurple 
library and the  plugins associated with protocols, include liboscar.so and 
libjabber.so.
But when we download the libraries to the board, liboscar and libjabber can 
not load correctly but other protocol plugins can be loaded like msn, yahoo 
etc. The debug message is :

1 What's wrong with our cross compile, do we forget some libraries.

2 yahoo protocol dose not support, a correct yahoo account will get a error 
password  message when connected.


3 how do I cross comple silc-client, I get an error when configure
"configure: error: cannot run test program while cross compiling
See `config.log' for more details."
I use silc-toolkit-1.1-beta3
