If gcj is in your pathyou should just be able to type "./configure --with-gcj-compile".The build process will generate the java and jni code andcompile the java and C code. This part of the build willuse your standard JDK and C compiler. Once this is complete it will compile the java code into a shared object usinggcj with the jni feature.</para></answer></qandaentry><qandaentry><question><para>How do I compile the examples using gcj?</para></question><answer><para>In order to compile the examples using gcjyou must first build the bindings using the"--with-gcj-compile" option.
