JNI on AIX.
Hello Guys,
We have received some c code from our client their encryption/decryption algorithams from our client which we have to integrate in our java code. I have written a java class with some native methods. And a c program which is called from java using JNI and this c program calls the functions from the code provided by our client. Taking togather my own c program and the progs provided by the client i create a dll file on windows and i can call all the functions properly. So no problems till this point. Now we have to deploy the project on AIX, I take the same code to AIX and now i am creating a .so file insted of dll, compilation and library creation is fine( I am using C for AIX Compiler, Version 5), i am creating the library with the command
cc -g -G -I/usr/WebSphere/AppServer/java/include/ *.c -o libVMD.so
invoking some of the native methods in my java class from a test program also works fine but with a couple of other functions the JVM is crashing
This is the output that i get on my command window
SIGILL 4 (*) illegal instruction (not reset when caught)
si_signo [4]: SIGILL: (*) illegal instruction (not reset when caught)
si_errno [0]: Error 0
si_code [30]: ILL_ILLOPC [addr: 0x0]

what i am doing wrong here? or if there are any other issues while using JNI on AIX.
All the help appreciated.
Thanks
