A study on the JNI interface of Java calling C + + DLL file--distribution function calculation

Have done some research on the VS platform running GNU Library and Java call VS2010 x64 bit system, then we will try to generate a DLL that calls the probability statistic function and run it in the Java program. When you are ready to generate a DLL file with a normal distribution function, the following error occurs:

The initial guess is that the lib file misplaced, all the Include files and Lib files are copied one copy, to

It's not going to work.

Join the following dependent libraries

Still no problem solved.

After numerous adjustments confirmed, in the 64-bit compilation environment, the failure

DLL succeeds in a 32-bit compilation environment.

Suspected to be related to the GNU system's own DLL or LIB version. Need to recompile their version.

Kind of like my situation.
