In the Java Tutorial JNI lessons, whenever you see '-G', replace it with '-shared' for gcc/egcs. All other compiler options are as you would normally use them ('-g' for debug, '-O' for optimization, etc.). I also recommend reading the 'jdk1.2/include/jni.h' and 'jdk1.2/include/<os>/jni_md.h' files (where <os> is your OS). The Java Developers' Almanac has a nice section with an overview of the JNI types and methods, as well - great for reference. -- Jeff Galyan http://www.anamorphic.com http://www.sun.com jeffrey dot galyan at sun dot com talisman at anamorphic dot com Sun Certified Java(TM) Programmer ====================================================================== Linus Torvalds on Microsoft and software development: "... if it's a hobby for me and a job for you, why are you doing such a shoddy job of it?"
