I'm running Ubuntu 8.04 (hardy) on an Intex Xeon server.
My java details:
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) 64-Bit Server VM (build 10.0-b22, mixed mode)

I'm not sure how to add the flag - do I extend one of the arguments or
add it as a new argument in the list?
I tried both of the following:
LFLAGS = {
'linux2': ['-L/usr/lib/jvm/java-6-sun/jre/lib/amd64', '-ljava', '-ljvm',
'-Wl,-rpath=/usr/lib/jvm/java-6-sun/jre/lib/amd64:/usr/lib/jvm/java-6-sun/jre/lib/amd64/server']
}
and
LFLAGS = {
'linux2': ['-L/usr/lib/jvm/java-6-sun/jre/lib/amd64', '-ljava, -ljvm',
'-Wl,-rpath=/usr/lib/jvm/java-6-sun/jre/lib/amd64:/usr/lib/jvm/java-6-sun/jre/lib/amd64/server']
}
I'm not sure why the Ubuntu package installer installed the AMD64
version of java, but I assume it's the one to use with a Xeon.
These both give a build and install without any problems:

Here is the ldd output. (I hope I'm pointing at the right file).

Once again, many thanks for looking at this. I'm a bit of a linux
newbie, so any help is much appreciated.
