The problem today is as follows: postgresql-pljava builds a postgresql extension that executes java code by executing it with (lib)gcj. Probably due to the above change, the old -lgcj can be replaced by -ljvm. Unfortunately, libjvm.so is in a place that needs a rather ugly -L/usr/lib/jvm/java-1.5.0-gcj/lib (or -L/usr/lib/jvm/java-1.5.0-gcj-4.4/lib) to work. So question 1 is * Is -L/usr/lib/jvm/java-1.5.0-gcj/lib -ljvm the right way to embed a JVM in applications? (or with -4.4 as the other one is only in gcj-jre-headless?) During build, dpkg-shlibdeps still complains about not finding libjvm.so * Shouldn't libjvm be mentioned in /var/lib/dpkg/info/libgcj10.shlibs so packages using it do depend on libgcj10? At runtime, pljava.so still needs a LD_LIBRARY_PATH = '/usr/lib/jvm/java-1.5.0-gcj-4.4/lib' or similar in /etc/postgresql/8.4/main/environment. * Is there a static path I can use? Would RPATH help?
