Ok....i did some research on this, it seems straight forward enough.
I have written the c++ file I want to encorporate -
basically all it does is call the clear screen function clrscr().

However, I was following the instructions to create a shared
library and this is where i seem to be having some trouble.
The code suggested to do so is as follows (For Windows)
cl -Ic:\java\include -Ic:\java\include\win32
-LD HelloWorldImp.c -Fehello.dll
That's fine - i updated this to point to where the include
directory is on my PC.
However, when I run this I get the following
fatal error C1083: Cannot open include file: 'stdio.h':
No such file or directory
Although stdio.h does exist - the thing is I do not call/use
this header file!.
Any help would be gratefully received
