I had to make some changes to the compilation options: Replaced -Tlinux with -Tandroid Replaced -CfVFPV2 with -CfVFPV3 Removed -mfloat-abi=hard Added new unit path (units\rtl-objpas, seems it was necessary for dateutils now)
Yes, the change to -Tandroid and the inclusion of rtl-objpas is expected. Afterall Android is now a fully supported target and the latter was because we've split up the RTL a bit.
My own exported functions are all declared in the main file. They are defined like this: Procedure Java_com_pascal_terra_TERRALibrary_ApplicationShutdown(env, obj:Pointer); stdcall; export; [public]; Begin ... End;
Better try to use an "exports" section in the mainfile instead of "export; [public];". See here (even related to Java) http://wiki.freepascal.org/Using_Pascal_Libraries_with_Java and here http://www.freepascal.org/docs-html/ref/refse100.html
Sidenote: the standard calling convention for Java is AFAIK "cdecl". It does not matter on ARM as there is all calling conventions are the same anyway, but on android-x86 that will matter...
Also the part "export; [public];" seems necessary in Android, otherwise they were also not exported correctly. I don't really understand what [public] means, and sadly could not find documentation about it.
Then you didn't look good enough ;) http://www.freepascal.org/docs-html/ref/refsu77.html#x185-19500014.9.12
Finally, in the end of the main file I have an exports section, listing all functions I want to export, all worked before so what changed that causes the symbols to not be exported in the .so?
Exporting functions without an "exports"-clause is a bit fragile. Could be that a bug was fixed or a bug was introduced. I don't know currently...
And why is this PASCALMAIN being exported, since I'm compiling a library not a program?
Even libraries have a main entrypoint. It's the "begin ... end." inside the library file and this one is also responsible for initializing all used units.
