[Bug java/20750] New: libgcj needs a --with-java-home configure option

[fitzsim at redhat dot com]

For java-gcj-compat, we need to define these system properties:

java.home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre
sun.boot.class.path=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre/lib/rt.jar

A --with-java-home configure option would allow these properties to be set.

Whats the advantage to setting these at configure time? Couldn't java-gcj-compat
just set them when it invokes gij?

It seems a little awkward to hardcode paths like "java-1.4.2-gcj-1.4.2.0" into
libgcj when this is really a property of java-gcj-compat.

The advantage is that we can then eliminate the java wrapper script completely
and symlink the java command directly to gij.

I should also mention; currently java-gcj-compat is separate from libgcj because
it depends on ecj.  Once gcjx lands we can use it as our bytecode compiler, and
distributions will likely want to merge java-gcj-compat into the libgcj itself.

Yeah, in the case where java-gcj-compat is merged into libgcj (ie libgcj is set
up to look like a JVM) then this option makes sense.

libgcj would install its .jars and whatever other JVMish files applications
expect to find into this directory, and set java.home accordingly. 

I don't see a reason why we couldn't go ahead and implement this on HEAD now,
even though an external wrapper would still be needed for now to use ecj as javac.

I so think it seems a bit non-intuitive to have --with-java-home just set a
property and not actually install things into that directory, relying on an
external package to actually populate it, however. We should at least install
libgcj.jar into the directory given?

Yes, eventually we'll install the same compatibiliy symlink forest we currently
install in java-gcj-compat.  For now though I only expect distributions
packaging java-gcj-compat to use this option.  For example, in Fedora Core,
java-gcj-compat is a default package, so we expect it to be there and we add an
rt.jar symlink from $JAVA_HOME/lib/rt.jar to libgcj-4.0.0.jar.  People
installing libgcj manually shouldn't use this option and won't be affected by it.
