I just installed cdt in my eclipse (windows). I got it working for a
simple hello world. But I then tried the following code:

#include <iostream>
#include <jni.h>

using namespace std;

int main() {
cout << "Hello, world" << endl;
}

And the compile failed due to the #include <jni.h>. My compiler is MinGW.
I'm not sure what is happening. I've tried adding /jdk1.4.2_10/include
into the include system environment variable and played with the linker.
But I really don't know what I'm doing. I'm very new to c/c++. I searched
earlier posts, but nobody seemed to ask this particular question. Thanks
for any help.

CDT 3.0.1? Right click on your project and select "Properties". Under
the GCC C++ Compilers you'll see "Directories". Click the Add button and
add your path. If you're adding the include directory, you'll probably
also have to include the win32 subdirectory, as jni.h just includes
another file from that directory. However, on my system, going to that
trouble just leads to yet other dependency problems. Bottom line, I
don't have this problem you're seeing as CygWin seemed to install enough
for mine to compile cleanly without specifying any beyond the default
set of directories. But at least now you know how to specify
directories... I hope that gets you further along.

Much appreciated. That did the trick.
