Question

I found this tutorial on Netbeans site < cause im using netbeans> on how to use JNI < which i have no clue about> and it said that i needed a gcc,make . how to get that and how to use it?
and when i set the environment variable to how can i find it in console in the final step where i need to create a header file?

Answer 1

JNI is a bridge to use C/c++ libraries. It makes your java code non-portable, but it allows you to use libraries instead of having to re-invent the wheel. I use it only to gain graphic capabilities for computer vision. Setting up the full use of Intel's OpenCV library is non-trivial, in fact it is a pain.



You will have to compile the C/c++ library and shared-library code on your machine before you can write the JNI wrappers. You need a good book on ANSI C. gcc is a compiler for the Linux world and Windows has their Mingw32 for open source offerings.



NetBeans is great for writing C code once you've got the compiler installed and ready to link.



good luck

Answer 2

In my opinion, working with Matlab is much easier than working with C or C++, but of course it's only a tool. Matlab is ready for GUIs, and for lots of mathematical calculations. You have to spend some time learning that tool, though... It's not trivial, but working with C is much less trivial...

Answer 3

gcc and make are binaries (or executable programs) use to compile C/C++ programs.



Follow this netbeans tutorial first:

P.S. I think you're way over your head on this one.
