1.123     jmc         3: This file (UPDATING) is intended to be a brief reference to recent
                      4: changes that might cause problems in the build process, and a guide for
                      5: what to do if something doesn't work.

1.123     jmc         7: For a more detailed description of the recommended way to build NetBSD
                      8: using build.sh, see the BUILDING file.

                     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.

        !            23:        GCC 7 switched for many ports.  Update builds are likely to fail.

        !            25: 20180924:
        !            26:        A newer OpenSSL version has been imported. If you are doing
        !            27:        update builds, make sure to remove all old obj dirs, like:
        !            28:        cd /usr/obj && find . -type d -name openssl | xargs rm -rf
        !            29:

        !            32:        to long. This requires recompiling all C++ binaries.

        !            34: 20180713:
        !            35:        On amd64 and i386 static binaries are now build position
        !            36:        independend. This requires recompilation of all object
        !            37:        files used to create the crunched /rescue binary.
        !            38:        Clean the rescue directory in your obj directory before
        !            39:        doing an update build, otherwise linking will fail.
        !            40:
1.293     jakllsch   41: 20180414:
                     42:        Existing binutils was migrated to binutils.old.  Manual
                     43:        removal of tools/binutils objects directory may be required
                     44:        to fix tools build failure.

                     48:        src/external/mit/xorg/tools/bdftopcf subdirectory if there are

1.291     mrg        51: 20180212:
                     52:        between OpenSSL and GCC updates, many things may fail to build.
                     53:        any failure that looks like GCC or openssl is best handled by
                     54:        a clean destdir and objdir.  Full cleandir and destdir deletion
                     55:        is recommended if build failures occur.

                     58:        removal of the vadvise syscall requires manual removal of all
                     59:        associated files from the libc build object directory (including
1.289     christos   60:        the .depend files) - a command like:
1.288     martin     61:                cd $OBJ && find . -type d -name libc | xargs rm -rf
1.289     christos   62:        For architectures that support multiple "compat" binary targets,
                     63:        you'll need to cleanup both the regular libc directory and the
1.290     martin     64:        compat ones (the above command will do that).
1.288     martin     65:
1.287     kre        66: 20171010:
                     67:        a change to the build structure of external/bsd/acpica/bin/iasl
                     68:        means that its objdir (or *.d and .depend at least) might need
                     69:        to be manually removed - or a build done once without -u.

                     74:        in the tools and the native section.  Remove all GCC, GMP, MPFR
                     75:        and MPC objdirs or build once without -u.

1.284     martin     83: 20170402:
                     84:        a new version of dhcpcd has been imported, which does not support
                     85:        update builds from the previous version. Remove your
                     86:        external/bsd/dhcpcd object dir or build once without -u.

                     90:        The structure of it has changed slightly from prior versions and
                     91:        an updated tic tool is required.
                     92:        If you build.sh, don't use -u

1.278     kre        95:        various arch dependent libc/exect.S files were removed
1.279     kre        96:        Either remove the obj directories (lib/libc and compat/amd64/i386/lib
                     97:        if it exists) or do a clean build.
                     98:        (This is a bug in the make system, it should be corrected without
                     99:        human intervention, but isn't.)

                    102:        xinput build options have changed.
                    103:        Remove the obj directory (external/mit/xorg/bin/xinput)

                    108:        Remove the file from obj (external/bsd/flex)

1.274     martin    116: 20161009:

                    118:        build infrastructure. When doing a build.sh -u this requires
                    119:        pruning the external/bsd/dhcpcd objdir.
                    120:

                    123:        ports in using xorg-server 1.18. This requires a clean destdir
                    124:        and a clean objdir.
                    125:
1.272     dholland  126: 20160527:
                    127:        i386 needs a full cleandir or objdir deletion because PIE has
                    128:        been enabled. (see the amd64 entry two down for further info)

1.270     christos  130: 20160418:
                    131:        libedit needs manual removal of all autogenerated files since
1.271     christos  132:        some of them are not autogenerated anymore. Remember that there
                    133:        might be two copies of libedit if your platform builds "compat".
1.270     christos  134:
1.268     riastrad  135: 20160410:
                    136:        amd64 needs full "make cleandir" or deletion of objdir now that
                    137:        PIE has been enabled for amd64.  PIE, or position-independent
                    138:        executables, means all code, including executables and not just
                    139:        shared libraries, is position-independent and hence able to be
                    140:        relocated by ASLR, address space layout randomization.
                    141:
                    142:        The change was made in Makefile variables for compiler and
                    143:        linker flags, for which make(1) does not record dependencies,
                    144:        hence it is unable to detect that all .o files need rebuilding.
                    145:
                    146:        Partial rebuilds with some modified source files will likely
                    147:        fail when linking executables, since the linker refuses to mix
                    148:        position-independent code with position-dependent code in
                    149:        position-independent executables:

                    154:        Ports switching to GCC 5.3 will need a full "make cleandir".
1.269     dholland  155:        Some people have found that cleandir is not sufficient, so if
                    156:        in doubt delete the entire object directory tree for gcc.

1.265     aymeric   159:        NetBSD's regexp implementation is now part of libnbcompat.
                    160:        Nblex, nbm4, nbpax, nbsed use it and they may crash on

                    163:        In any case, you should "make cleandir" at least these tools
                    164:        before updating your toolchain.

1.264     martin    166: 20160125:
                    167:        Dtrace has been enabled by default on some architectures.
                    168:        When doing an update build, make sure to clean the etc/mtree
                    169:        object directory before starting the build - otherwise the
                    170:        needed directories in destdir will not be created.
                    171:        An easy way to do this is:

                    186:        do a make cleandir in src/tools/lint1 and
