Compiling a JNI file in Dev-C++ and Code::Blocks

Hello!
When I compile a hello.DLL file as it says in JNI tutorial on Java web-site:
http://java.sun.com/docs/books/tutorial/native1.1/stepbystep/index.html, it gives me an unsatisfied linker error. But when I do the same thing in Dev-C++ everything works fine. Also a DLL file produced by Dev-C++ is about 1 KB bigger. There is probably one little check box I need to tick, but I have no idea where this check box is and where to look for it.

Thank you!

Hello,

Could you post with the link error you get (the C::B build Log)?

kostyabkg:
I am sorry for being not clear enough. I get this error when I launch the java file. I just followed the tutorial in both cases, but the file compiled by Dev-C++ run correctly while being invoked by my java program, whereas when my java program is trying to invoke the DLL file created by Code::Blocks it gives me this error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: displayHelloWorld
        at HelloWorld.displayHelloWorld(Native Method)
        at HelloWorld.main(HelloWorld.java:9)

In this java trail it says about an error, but the error they quote there is a little different from the one I get. It just seems to me that this file somehow doesn't "interact" with my Java program, but what the problem? I don't have a clue... And why Dev-C++ works?

Michael:
Ok. Thanks for the explanation.

I have reproduced the same error by following the JNI tutorial. I will try to check what is wrong.

Michael:
That's interesting. If I use the MS Toolkit 2003 compiler all works fine. But with GNU GCC... :?.
