[fpc-pascal] Android and cwstring

[Torsten Bonde Christiansen]

Hi,

I'm trying to create a library for use in an android application, but 
i'm having a hard time getting it to work correctly.

More specifically i cannot get the library to use the "cwstring" unit. 
Below you see a working example of a library that works fine (the log 
entry is generated) when cwstring i commented out, but when included the 
android application just hangs on the message:

07-31 16:52:16.284: D/dalvikvm(338): Trying to load lib 
/data/data/dk.epidata.epidatatestproject/lib/libepitest.so 0x45f3e268

The error is most likely mine, my experience with android programming 
and libraries are limited, but I fail to see what I am doing wrong in 
this case.

Just for record i use:
torsten at Rainier:~$ ppcrossarm -i
Free Pascal Compiler version 2.7.1

Compiler Date      : 2013/07/25
Compiler CPU Target: arm

Settings for android in .fpc.cfg:
-CfVFPV3

#ifdef cpuarm
