Re: [xmlvm-users] Using the posix backend

[Bruce J. <bru...@go...>]

Yes, thats correct.

Much of the work you have done in the patch is already included in the trunk build if I look at the source. Being a novice to this project, I was wondering when the native libraries are actually built. The instructions on the XMLVM site say that:

cd xmlvm
ant
ant demos

However, this doesn't seem to rebuild any of the native C code. Are these built on demand when xmlvm is actually executed? If not, how do I rebuild the native C libraries?

Thanks

Bruce
