I got random failures in buildworld as well as in a few ports. I never had any failures in normal operations and the errors were, when closely checked, often things like unlinking files and changing file attributes, not in the actual compile. I fixed the problem by building a re-starting the build with -DNOCLEAN. Eventually, the whole thing built. I had to make sure I was not doing something that might leave damaged files around, especially incomplete libraries, that would cause make to not rebuild them. It did take a while. Once I had built the new system and kernel, I installed them and immediately did a complete rebuild of the system and kernel just in case something was not quite right. My T30 has been happily rebuilding 2 or 3 times a week since then with no further problems. Good luck! -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
