Hi…

I have build a program for the Velleman K8000 interface card, in java, which works just fine in windows, but now I want to use the program on a Unix-System.

Is it possible to somehow convert the dll file to a format that Unix supports, or do I have to find another way?

Dll-file: jnpout32pkg.dll

Not directly as I know of. Do you have the sources of this DLL? You can try to recompile it on Unix (if compatible) and use JNI to bootstrap it from Java.

Not sure whether I misunderstood your question ....

The source for the dll file is loacated in this zip-file, but i don't know how to re-compile it for unix.

Good. The package already uses JNI. If you open some of the CPP and Java files, you already see uses of JNI. For further information about JNI, see

Probably the major problem is that C/C++ programs are usually platform dependent, so a C/C++ program may not compile on a different OS or compiler. From the sources, it appears that it was originally intended for Visual Studio + Windows, so expect some porting work before you can actually use something JNI on Unix.

EDIT: I just saw a hwinterface.sys inside. Probably it is a binary produced by an assembler which contains the real meat of the I/O, but no source is available. For this particular package, I don't think you can use it on Unix successfully.
