[fpc-devel] About building JNI library for arm-linux

[Gennady Agranov]

Hi,

I have an issue with loading JNI library for Raspberry :(

I do compile with -Cg -WX and stack checking on (and also without).

But even this method is not called :(

function JNI_OnLoad(vm: PJavaVM; reserved: pointer): jint; {$ifdef 
linux}cdecl{$else}stdcall{$endif};
begin
   writeln('lll');
   exit(0);
end;

Any suggestions?

Thanks,
Gennady

Java HotSpot(TM) Client VM warning: You have loaded library 
/media/pi/Transcend/cypress-release/pas2jni_policing64/policing64/policing.so 
which might have disabled stack guard. The VM will try to fix the stack 
guard now.

It's highly recommended that you fix the library with 'execstack -c 
<libfile>', or link it with '-z noexecstack'.
