Just because your cpu can't run 64bit code does not mean that it cannot build 64bit code. Our makefiles are setup to build all possible architectures for a family (ie, x64/x86 vs sun4u/sun4v). I don't believe that hacking them to do cpu capability detection and not build bits is a viable use of anybody's time. I don't know why you're not getting Makefile.master.64 - perhaps you rm'd it? In any case, you should be able to get a copy of it by running (from the top of your tree, ie, above usr/src): $ hg revert -r tip usr/src/Makefile.master.64 James C.
