hotspot build instructions

[Prasad Kulkarni]

Thanks everyone for your help.
My research only involves making changes to the hotspot JVM. I do not want to build the class libraries and anything else that I don't have to. Earlier this week, I downloaded just the hotspot compiler from one of Sun's site (not the OpenJDK) and built it on fedora/gcc 4.1.2 after making some changes to the source files, mainly due to gcc incompatibilities, I believe. I also downloaded the latest java SDK hoping that just by replacing the libjvm.so file all would work.

Since that did not work, I started looking at the OpenJDK project. One question I have is, exactly how much of the entire JDK does one have to build to start customizing hotspot? The hotspot FAQ page provides instructions to get the source for the hotspot VM. Those links did not work for me, in particular the one for the source bundle, 
https://openjdk.dev.java.net/servlets/ProjectDocumentList?folderID=6127&expandFolder=6127&folderID=0

So, I have been attempting to download the OpenJDK using Volker's instructions on his weblog. Currently, I don't have all the files as yet, mercurial only downloads 26 files without hgforest. So, I will try to solve those issues today. Please let me know if any one has any suggestions.

thanks,
Prasad
