Hi, I am a developer working in jni in windows platforms and wanted to setup a dll for the header file created after running javah on the c file. It would be of great help if anyone could help me out with the gcc options and syntax in this regard.(I am using the gcc 3.4 series of compiler on the windows command prompt).
