Actually, only a few java commands are needed to be run by another java instance during the build. The attached documents how I went about getting a native jdk15 running for amd64. It can be done, but it's a little quirky to set up. Regards, - Håvard

One can use a bootstrap JVM from another host (and architecture) and some scripts which use ssh to the bootstrap host and sharing files via NFS -- that's how I bootstrapped the NetBSD/amd64 version using the NetBSD/i386 version. I've attached my notes and the scripts I used to do this. (Admittedly, I've since tweaked the scripts to use environment variables, so they've not been tested in their present form...) Best regards, - HåvardMy notes for using a JVM on NetBSD/i386 to bootstrap JVM on NetBSD/amd64: I used a set of script wrappers which ssh to another machine (in my case running NetBSD/i386, with its native java installed) which has the same directory tree available via NFS as on the target (amd64) machine, using the exact same paths. Substitute scripts were made for java, javac, javah, and jar, and the ALT_BOOTDIR was pointed to the directory tree containing those scripts. Some peculiarities were discovered: o java needs to be able to read from stdin. This means you can't use "ssh -n", which again means that the build job has to run in the foreground with access to the tty (yuk...). o javah gets at least once passed a class name with a $ in it. This causes issues because we get a double shell interpretation which leads to variable expansion; once on the local machine, once on the remote. To work around that problem I borrowed the "shquote" shell function from pkgsrc and tweaked the argument list using it (it's included). o the jar script sleeps 10 seconds because otherwise it would trip over "stale NFS file handle" problems when some files were copied in place (replaced) on the NFS server just prior to using "jar". Attached below is the set of scripts which I placed in /usr/pkg/java/ as boot-java/, packaged up as "boot-java.tar.gz". Set JAVA_BOOTHOST (your boot host) and JAVA_BOOTDIR (top of java directory tree on JAVA_BOOTHOST) in the environment to suit your config. I also include the "build-java" shell script I used (to be executed from the top of the Java source tree).Attachment: boot-java.tar.gz
