[Mingw-users] A simple DLL building script needed

[IT L. <cl...@ya...>]

Hi,
I am asking a very naive question.
I have a simple C++ file called JNI_Wrapper.cpp which calls some 3rd party APIs which are in   C:\Mobile\distro\lib\com_api.dll,  and I haver installed the MinGW 5.1.4 on Windows XP.  I can see the gcc/g++ on C:\MinGW\bin directory. 
What is the MinGW command (just a simple command) to compile the JNI_Wrapper.cpp into a Windows DLL so that I can invoke it from the Java program? 
BTW, it would be perfect if you guys know any open source Java utilities which would enable me to directly call 3rd party C/C++ API in a DLL.  I found one NON OPEN SOURCE Java utility called   jinvoke  could do it.
Thanks,
