Robin, Hmmm... This looks like a POSIX versus Solaris GCC issue. Keep in mind that I developed this on Solaris 9, but with POSIX compliance in mind where possible. I figured that if and when we came upon such issues as these, we would solve them when we got there. I guess we are there now ;-)
Perhaps there is a Linux equivalent to the interval timer below, or, better yet, a generic POSIX equivalent. I would like to use POSIX facilities whereever possible to maximize portability. Maybe we'll have to support explicitly Solaris and Linux, but who knows yet? We're just getting started. FYI-- This part of the code is _sure_ to contain the most exposure to such issues due to the OS facilities it invokes. This will be true for _all_ platforms to which this code is ported. Concerning build utilities, each directory under 'bootJVM' itself has an Eclipse project file for use with Eclipse and its C/C++ module. See 'config.sh' and 'README' for more info here. Do we need to add '.' to the include path? This should be a simple change and benign, even if on some platforms it is redundant. Perhaps some versions/platforms for GCC need it and some don't. But if it is added, it will solve the problem for all platforms. I am an avid fan of 'gmake', and always like to recommend it since I have built _exceedingly_ complex projects with it (like numerous languages, custom toolkits, specialized application scripts, multiple platforms for part/all code, etc.). If you are interested in this, I would be _glad_ for you to do some work with this "real build tool", as you rightly call it.. 8-) (Please let me know so we can strategize to make it complete yet simple.)

I'm running gentoo with a 2.6.13 kernel and gcc 3.3. By the way, the top level config.sh/build.sh seems to expect that "." is in the path. And any chance of getting this to build using a real build tool ? Make ? Ant ? (or is ant only for java ?) cheers Dan Lydick
