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@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
-Xd
-FD/home/torsten/AndroidDev/android-ndk-r8e/toolchains/arm-linux-androideabi-4.7/prebuilt/linux-x86_64/bin
-Fl/home/torsten/AndroidDev/android-ndk-r8e/platforms/android-14/arch-arm/usr/lib
-XParm-linux-androideabi-
#endif
Regards,
Torsten B. Christiansen.
====== library code ======

cmem, // includin cmem makes no difference
cwstring // including cwstring make the library halt on load... :(
