 This file is intended to be a brief introduction to the build  This file (UPDATING) is intended to be a brief reference to recent
 process and a reference on what to do if something doesn't work.  changes that might cause problems in the build process, and a guide for
   what to do if something doesn't work.
   For a more detailed description of the recommended way to build NetBSD
   using build.sh, see the BUILDING file.
   Note that much of the advice in this UPDATING file was written before
   build.sh existed.  Nevertheless, the advice here may be useful for
   working around specific problems with build.sh.

         make MKINFO=no dependall install          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
 20030630:          needed -- lint must be disabled temporarily, e.g.:
         Groff was updated to 1.19; it's probably necessary to do            $ (cd lib/libc && make MKLINT=no dependall install)
                 cd share/mk && make install

         now setgid to the smmsp group, and runs in "collection"            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         mode for most common activities, there is a new config            $ (cd sbin/drvctl/ && nbmake-$arch all)

         The generic submit.cf sample in /usr/share/sendmail/cf          leaves new drvctl utility in sbin/drvctl build directory.
         is named netbsd-msp.cf.  Upgrading your regular sendmail  
         configuration file is also strongly advised.  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.

 20021219:          The it(4) driver has been renamed to itesio(4) and the old port

           configuration file appropriately or see GENERIC for more details.
         The build system was modified to take advantage of  
         this option (using ${NETBSDSRCDIR}/etc), so if you  20071028:
         use USETOOLS==no, you may have to rebuild and          The pccons(4) driver has been removed from the NetBSD/shark port.
         reinstall usr.bin/xinstall first.          You need to update any custom kernel configuration file you have
           to remove any references to pccons (which includes removing the
 20021130:          now useless XSERVER option) and replace them with the correct

         A bug related to how ARM ELF objects were tagged has been  20070412:

         MKDYNAMICROOT=yes enabled by default, which means that          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         certain shared libraries are installed into /lib, the shared          to ACPI_SCANPCI. Thanks to work from fvdl.
         linker is installed into /libexec, and all programs in /bin  
         and /sbin are dynamically linked.  20060627:
         If you do not use "make build", you should ensure that          socket(2) has changed, and its system call has been versioned.
         you have the libraries and shared linker in the new locations,          For userlands with the old version of socket(2), make sure that
         with:          your kernel has 'options COMPAT_30' set, or else 'bad system call'
                 make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so          errors will result.
         USE_NEW_TOOLCHAIN has been replaced with:  
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which  
                 there is no working in-tree toolchain (hppa, ns32k, sh5,  
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the  
                 root of an external toolchain (e.g. /usr/local/gnu).  This  
                 enables the cross-build framework even for TOOLCHAIN_MISSING  
         gehenna-devsw has been merged into the trunk. Need to update and  
         reinstall usr.sbin/config before building the kernel.  
         Crunched rescue tools (contents of /bin and /sbin, plus others)  
         are now provided in /rescue.  
         To ensure that these are built statically linked (no matter  
         what the setting of LDSTATIC is), use a crunchgen(1) built  
         from sources newer than 20020820 (see the next entry).  
         crunchgen(1) changed to ensure that the generated program  
         is statically linked.  
         Solution: update and reinstall usr.bin/crunch  
         smmsp user/group has been added for sendmail.  
         Add the following into /etc/group:  
         and the following to /etc/master.passwd (via vipw):  
         smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin  
         sshd user/group has been added.  Need to hand add this in, or sshd  
         will not let you log in (with default, or UsePrivlegeSeparation=yes)  
         Add the following into /etc/group:  
         and the following to /etc/master.passwd (via vipw):  
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin  
         Also /var/chroot/sshd directory needs to be present (digged as part of  
         the build process).  
         NBUILDJOBS obsoleted in favor of just using -j.  
         etc/postinstall added, which performs various checks for  
         configuration file updates and changes, and can fix most of  
         the problems identified.  
         This should make it much easier to upgrade a system's  
         configuration from earlier systems (as far back as NetBSD 1.5).  
         <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.  
         Build and install at usr.bin/xinstall before the build.  
         Raw IPv6 socket now makes strict checking for sa_family and sa_len  
         on send(2) operation.  Be sure to have sbin/rtsol and usr.sbin/rtsold  
         newer than November 2001 when you upgrade the kernel.  
         ssh configuration files were moved from /etc to /etc/ssh.  Beware  
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).  
         Users of the VAX port will need to rebuild and install gas  
         so it deal with the now present register prefix used in all  
         the VAX assembly files.  
         ntpd user/group has been added.  Need to hand add this in or builds  
         will break as mtree aborts early.  
         Add the following into /etc/group:  
         and the following to /etc/master.passwd (via vipw):  
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
         If you're attempting to build a snapshot on sparc64 and are getting  
         reloc errors from the toolchain groff binary this means your native  
         toolchain has some broken C++ bits.  
         To fix:  
         Build a new toolchain (i.e. build.sh -t)  
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
         After this a snapshot will be able to be built.  
         In order for a sparc64 build to work you must have a working awk. If  
         you've built and installed a system with the new toolchain up to this  
         point you do not have a working awk as its ability to do floating  
         point is broken.  
         To build:  
         remake and install gnu/lib/libgcc  
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links  
         against the new libgcc.a)  
         Kernel config information was changed to use defflag in  
         the various "files" files.  Bug fixes to config(8) are  
         required in order for this to work properly.  Make sure  
         to build and install in usr.sbin/config before attempting  
         to build a new kernel.  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  
         The new document BUILDING.mdoc (view with nroff | more, or  
         see pre-generated .txt and .html versions) describes the build  
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN  
         build process, are intended in the long run to replace this  
         manual update log.  
         Users building a USE_NEW_TOOLCHAIN system should read the  
         BUILDING document for caveats.  Generally, BUILDING supersedes  
         UPDATING for these systems, as tool updating is taken care of  
         by the new build system.  
         src/etc/Makefile now needs install to be able to handle  
         symlinks that point to nowhere. A bug in install that  
         prevented this was corrected.  
         Solution: update and reinstall usr.bin/xinstall  
         Better Solution: Use the new toolchain and it will just work  
         for you.  
         /etc/mtree/NetBSD.dist has been updated to take advantage of  
         absolute path support added to mtree(8). Older mtree(8)s don't  
         understand the format.  
         Solution: update and reinstall usr.sbin/mtree  
         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  
         The new "ubcperf" code committed by Chuck Silvers removed  
         a header file, uvm/uvm_vnode.h.  There may be stale .depend  
         files that still reference this file.  
         Solution: "make cleandir && make dependall" in affected  
         grep.info is now built from grep.texi using makeinfo.  Since it  
         requires makeinfo v4.0, you need to install new texinfo before  
         building gnu/usr.bin/grep.  To install new texinfo, please follow  
         the instruction described in 20010726 entry.  
         (i386 only): i386 kernel now uses new instructions like  
         `fxsave' which old gas doesn't understand.  To build the  
         kernel successfully, you need to build and install a new toolchain,  
         (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"  
         from your kernel configuration until you rebuild your userland.  
         See 20011029 above and BUILDING file in this directory for more information.  
         [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]  
         Bootloader update on ELF platforms.  DDB in kernels from before  
         this will be unable to read symbol tables provided by newer  
         Texinfo was updated to 4.0.  To avoid failures when trying to  
         build the included texinfo files, do:  
         cd src/gnu/usr.bin/texinfo  
         make MKINFO=no dependall install  
         Enabled correct .init/.fini processing in crt0.  The way this  
         was done was to change a -I directive to cc(1), which means  
         make(1) will have a stale dependency (it will be checking the  
         timestamp on the wrong "dot_init.h").  
         The symptom you will see is that new programs die with SIGSEGV  
         if you have a stale dependency.  
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so  
         before starting your build.  
         A construct was added to uvm_page.h that uncovered a bug  
         in lint(1).  If you get a warning/error about a non-portable  
         bitfield, update your lint(1) before proceeding.  
         Added named user/group to system. Need to hand add this in or builds  
         will break as mtree aborts early.  
         To work around add by hand:  
         to /etc/group and add:  
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin  
         to master.passwd (use vipw for instance if doing by hand).  
         Now a make build should progress.  
         get/setprogname() added. Any hostprogs that may use this will need  
         to be bootstrapped manually until the host system is current.  
         Known problems: sys/arch/macppc/stand/fixcoff  
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to  
                           CFLAGS and rebuilding should work)  
                         usr.sbin/mdsetimage - Build a static copy if  
                           building a snapshot before fully bootstrapped.  
         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  
         introduce .if commands(target) in make(1). You need to  
         bring everything up-to-date first, then without installing  
         anything make and install in usr.bin/make, then proceed  
         with make build.  
         bsd.subdir.mk committed 20001230 had a bug which caused  
         afterinstall targets to run too soon; update again.  
         New share/mk files needed to support .WAIT in SUBDIR variables.  
         If you get make errors,  
                 (cd share/mk; make install)  
         Also, PRINTOBJDIR has changed and is now used more heavily.  
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  
         The following make directives are obsoleted.  
         By default, RSA is built into libcrypto.  IDEA and RC5 will not be  
         built into libcrypto.  By using MKCRYPTO_{RC5,IDEA}, you can build  
         additional library libcrypto_{idea,rc5}.
