                      3: This file is intended to be a brief introduction to the build
                      4: process and a reference on what to do if something doesn't work.
                      5:

                      9: experience the problems listed below because their host tools are

        !            16:         /usr/src/build.sh exists as of 2001.10.19. From the cvs log:
        !            17:
        !            18:         "Script to automate bootstrapping a build on any host platform.
        !            19:          Creates a bmake (rebuilds, if necessary) and invokes that to
        !            20:          start the build."
        !            21:
        !            22:         This should, incidentally, allow 1.5.x hosts to build -current
        !            23:         using the new toolchain, on USE_NEW_TOOLCHAIN-enabled platforms.

                     27:        symlinks that point to nowhere. A bug in install that
                     28:        prevented this was corrected.
                     29:
                     30:        Solution: update and reinstall usr.bin/xinstall
                     31:        Better Solution: Use the new toolchain and it will just work
                     32:        for you.

                     36:        absolute path support added to mtree(8). Older mtree(8)s don't

1.36      tv         52:        environment in order to build the system.  This is a pathname

                     62:        a header file, uvm/uvm_vnode.h.  There may be stale .depend

                     70:        requires makeinfo v4.0, you need to install new texinfo before
                     71:        building gnu/usr.bin/grep.  To install new texinfo, please follow
                     72:        the instruction described in 20010726 entry.

                     79:        "options I686_CPU" from your kernel configuration until you

                     97:        was done was to change a -I directive to cc(1), which means
