This always seems to be the case in 64 bit systems (AFAIK also on Windows 64b). If it gives some comfort: on Mac OSX it is worse. The Java libs and executables have been scattered all over the place there and often seem to be moved into other locations with new OSX version. Anyway, Michael (Java package maintainer) is the one to give advice here. I recently committed a preinstall.m to svn that looks for the executables and the jvm lib in the known places and aborts the Java pkg installation if they cannot be found. That helps in the sense that unwary users are not left with Java package installations that didn't yield errors but in fact are still half-baked. I did think of having the script add the relevant symlink automatically (AFAIK it is only needed for the jvm library) but in many situations one needs to have admin/root credentials for that. I think I left this option out as I'm not sure if fooling around in the system setup is the right thing to do for ordinary users, let alone user application scripts. But I could amend it to at least warn if the symlink is needed but the user doesn't have the required privileges; perhaps that is already in place anyway, I forgot. > Anyway I think this discussion should go to octave forge where the java > package is maintained not to the octave helper list, I put the > corresponding dev list on CC and would think that from the next reply on > help-oct...@octave.org should be removed from CC.
