Hi Shea, I am sorry for my ignorance, but... why is /opt not an appropriate location for OpenJDK??
OpenSCG's installer binaries for OpenJDK 6 are built on CentOS 4, install in a directory under /opt (when installed as root). They seem to work fine in all the modern Linux Distro's without doing anything funky/extra with LIB files. I believe this is similar to how Oracle builds their commercial JDK bu ilds, but, perhaps I am naive. :-) --Luss http://openscg.org On Sun, Jan 2, 2011 at 6:17 PM, Shea Levy <[email protected]> wrote: > Hi all, > > I've just successfully built openjdk6, and am wondering about the best way > to install it on my system, given that the /opt prefix is no longer > obviously appropriate for the build.
