Create DLL using JNI  RSS feed

I am trying to use the Java Native Interface(JNI) to compile and run a simple program. I am following the steps found here: http://java.sun.com/docs/books/jni/html/start.html#27008



I have gone through the first several steps successfully.

1) I created a Java program with appropriate native methods


2) I called javah -jni on my class file to create the C style header file



3) I wrote the implementation specified by the header in C++



4) Now I am at the step when I need to compile the C++ file and generate the .dll
I initially tried running this command:


but when I ran this I got an error:
C:\Program Files\Java\jdk1.7.0\include\jni.h(39) : fatal error C1083: Cannot open include file: 'stdio.h': No such file or directory

So the command I am trying to run now is:


And When I run this I get:
LINK : fatal error LNK1104: cannot open file 'libcpmt.lib'
Which doesn't make any sense to me beucause 'libcpmt.lib' is on my PATH variable and should be including in the cl command because I point -I to the directory it is in.


Has anyone encountered this issue?
Any help would be great.
Thanks

P.s - I have also posted this question on the Microsoft Visual C++ forum here: http://social.msdn.microsoft.com/Forums/en-AU/vcgeneral/thread/2b79c6f4-eef8-4e85-851f-10a09e725f8f

Someone answered my question on the MSDN site. The problem was before I could compile the DLL I needed to run



Which is located in the C:\Program Files\Microsoft Visual Studio 9.0\VC\bin folder


Cheers
 
It is sorta covered in the JavaRanch Style Guide.
