Hello All I have previously posted a question on the use of GCJ and has progressed somewhat on my own but I have hit another roadblock. My attempts to compile the software lead to reference not found for the imported jcifs classes. Googling around seems to indicate that I need to compile the jcifs-1.3.14.jar before I can use it for runtime linking instead of just adding it into the classpath. This is where I got confused as I am using a Windows x386 MingGW version of GCJ to compile my software. Is the steps for Linux, ie compile .jar to .so and setup a LD applicable? Can someone this point the way? I originally attach the source and jar in the form of a 7-zip package but the mail daemon rejected it as it exceed 400K bytes. 1. Uncompress using 7-zip into any directory. 2. Run build.bat that executes the command that I use to attempt to build my software. TIA. Vincent
