Well, solutions look good, but there's a couple of point about that: 1. You do not need modify header file, only put: -D__int64="long long" To the command to compile. 2. I can create a .dll, but it's still have depend of cygwin1.dll... why? I put "-mno-cygwin" and still look for that file. Hi!

Though i would recommend the following instead as it does not involve modifying the 3rd party header file. in your file before you reference enter the following line typedef long long __int64; Hi, Thanks for pinpointing the problem with the __int64. Though i would recommend the following instead as it does not involve modifying the 3rd party header file.

in your file before you reference enter the following line
typedef long long __int64;

I prefer this approach since it doesn't require installing Cygwin or changing any JDK files. It took me a little while to figure out the syntax with Ant (and requires an Ant library from Sourceforge), but I prefer this approach (since I like having a simple-to-setup build environment). If you want any details, email me at gpayne@artium.com.
