doesn't work on windows

was trying to compile it with mingw and vc 2008, but even after adding the correct includes from the jdk (subdir "win32"), I get this error:

C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG "-Ic:\Program Files (x86)\Java\jdk1.7.0_05\include" "-Ic:\Program Files (x86)\Java\jdk1.7.0_05\include\win32" -IC:\Python27\include -IC:\Python27\PC /Tcjnius\jnius.c /Fobuild\temp.win32-2.7\Release\jnius\jnius.obj

I've hit this bug too. What I've done is modify this line in jnius_jvm_desktop.pxi as said on IRC:

cdef extern jint  __stdcall JNI_CreateJavaVM(JavaVM **pvm, void **penv, void *args)

After that it looks like the linker has some issues with it:

build\temp.win32-2.7\Release\jnius\jnius.o:jnius.c:(.text+0x11d1): undefined reference to `__imp__JNI_CreateJavaVM@12'

These are the additions I've made to the setup.py in order to try and comply with the needed reference for that function:

elif platform == 'win32':
    cpu = 'i386' if sys.maxint == 2147483647 else 'amd64'
    jdk_home = environ.get('JDK_HOME')
    jre_home = environ.get('JRE_HOME')
    cpu = 'i386' if sys.maxint == 2147483647 else 'amd64'
    include_dirs = [ join(jdk_home, 'include'), join(jdk_home, 'include', 'win32')]
    library_dirs = [ join(jre_home, 'bin', 'server') ]
    extra_link_args = ['-Wl,-rpath', library_dirs[0]]
    libraries = ['jvm']

but no luck.
Any suggestions on how to fix that is appreciated.

This configuration worked for me:

elif platform == 'win32':
    cpu = 'i386' if sys.maxint == 2147483647 else 'amd64'
    jdk_home = environ.get('JDK_HOME')
    jre_home = environ.get('JRE_HOME')
    cpu = 'i386' if sys.maxint == 2147483647 else 'amd64'
    include_dirs = [ join(jdk_home, 'include'), join(jdk_home, 'include', 'win32')]
    library_dirs = [ join(jdk_home, 'lib'), join(jre_home, 'bin', 'server') ]
    extra_link_args = ['-Wl,-rpath', library_dirs[0]]
    libraries = ['jvm'] 

After building, there is a file "jnius.pyd" which is the DLL, so rename it to "jnius.dll".

I used this guidance in a pull request to get Windows working. Thanks!
