                      4: changes that might cause problems in the build process, and a guide for
                      5: what to do if something doesn't work.

                     10: Note that much of the advice in this UPDATING file was written before
                     11: build.sh existed.  Nevertheless, the advice here may be useful for
                     12: working around specific problems with build.sh.

        !            29:        build infrastructure. When doing a build.sh -u this requires

        !            34:        ports in using xorg-server 1.18. This requires a clean destdir
        !            35:        and a clean objdir.

1.272     dholland   37: 20160527:
                     38:        i386 needs a full cleandir or objdir deletion because PIE has
                     39:        been enabled. (see the amd64 entry two down for further info)

                     42:        libedit needs manual removal of all autogenerated files since
1.271     christos   43:        some of them are not autogenerated anymore. Remember that there
                     44:        might be two copies of libedit if your platform builds "compat".

1.268     riastrad   46: 20160410:
                     47:        amd64 needs full "make cleandir" or deletion of objdir now that
                     48:        PIE has been enabled for amd64.  PIE, or position-independent
                     49:        executables, means all code, including executables and not just
                     50:        shared libraries, is position-independent and hence able to be
                     51:        relocated by ASLR, address space layout randomization.
                     52:
                     53:        The change was made in Makefile variables for compiler and
                     54:        linker flags, for which make(1) does not record dependencies,
                     55:        hence it is unable to detect that all .o files need rebuilding.
                     56:
                     57:        Partial rebuilds with some modified source files will likely
                     58:        fail when linking executables, since the linker refuses to mix
                     59:        position-independent code with position-dependent code in
                     60:        position-independent executables:

1.267     mrg        64: 20160401:
                     65:        Ports switching to GCC 5.3 will need a full "make cleandir".
1.269     dholland   66:        Some people have found that cleandir is not sufficient, so if
                     67:        in doubt delete the entire object directory tree for gcc.
1.267     mrg        68:
1.266     aymeric    69: 20160306:
1.265     aymeric    70:        NetBSD's regexp implementation is now part of libnbcompat.
                     71:        Nblex, nbm4, nbpax, nbsed use it and they may crash on

                     73:        while they included a non-NetBSD regex.h.
                     74:        In any case, you should "make cleandir" at least these tools
                     75:        before updating your toolchain.
                     76:
1.264     martin     77: 20160125:
                     78:        Dtrace has been enabled by default on some architectures.
                     79:        When doing an update build, make sure to clean the etc/mtree
                     80:        object directory before starting the build - otherwise the
                     81:        needed directories in destdir will not be created.
                     82:        An easy way to do this is:
                     83:           cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir

                     91:        in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and

1.261     martin     94: 20150404:
                     95:        Lint changes require a full rebuild of the tool, so make
                     96:        sure to build without -u option to build.sh, or manually
                     97:        do a make cleandir in src/tools/lint1 and

                    102:        the openssl libraries will fail. A make cleandir in
                    103:        external/bsd/openssl/lib is needed

1.259     msaitoh   106:        A mishap during the import of pppd may cause your corruption
1.258     martin    107:        in your cvs directory if you happened to do a cvs update
                    108:        during a short period of time. To fix, just remove the
                    109:        directory src/external/bsd/ppp/dist/pppd completely
                    110:        and let cvs restore it on next update.

                    114:        and then deleted in the CVS repository.  If you get errors like

                    123:        rebuilding all C++ code. It is strongly advised to do a clean build.

1.251     martin    125: 20140131:
1.253     joerg     126:        The new compiler_rt/libc integration moved a few things. It is strongly
1.254     skrll     127:        advised to do a clean build. At least lib/libc, the compat version(s)
1.253     joerg     128:        of libc, libkern, rump and the kernels need to be cleaned.

                    132:           attacks. If you need ntpdc to work you need to explicitly enable
                    133:           mode7 in your config file. Make sure you put the necessary restrict
                    134:           statements to avoid being exposed.
                    135:        2. strncat has moved from lib/libc to common/lib/libc; you might need
