 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.

         mountd got restarted because it freed memory that had already          Since this breaks the libc build itself, manual help is
         been freed. This has been fixed and the kernel checks          needed -- lint must be disabled temporarily, e.g.:
         export addresses very strictly. If you upgrade your kernel,            $ (cd lib/libc && make MKLINT=no dependall install)
         make sure you also upgrade mountd, because if your export  
         file contains lines with an old inet4 address syntax (i.e.  20080813:
         a.b.c or a.b or a), they will get rejected by the new kernel.          MKDEBUG build was broken because the .depend files did not know
           about .go files. You need to remove all .depend files and rebuild.
 20030402:  
         The superblock layout for FFS was changed.  If you have 1.6  20080731:
         fsck binaries, they will signal a fatal superblock mismatch          WAPBL (metadata journaling support) has been added, but at this
         with the first alternate, because they compare too many          time isn't backwards compatible with pre-WAPBL aware kernels
         fields (even ones that aren't useful).  If possible, upgrade          and userland (fsck_ffs in particular).  Please make sure you
         your fsck_ffs binary before using a new kernel.          don't use a journaled filesystem with an older kernel/userland,
         None of this signals actual filesystem damage.          especially an uncleanly mounted journaled filesystem.  WAPBL
           also requires the super block to be in the UFS2 format.  You
 20030324:          can use fsck_ffs -c 4 to update the superblock format.
         sendmail version 8.12.8 was imported.  Since sendmail is  
         now setgid to the smmsp group, and runs in "collection"  20080721:

         is named netbsd-msp.cf.  Upgrading your regular sendmail  20080531:
         configuration file is also strongly advised.          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
           from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)

         make MKINFO=no dependall install  20080503:
           The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
 20021223:  
         The METALOG format changed slightly, to remove the leading  20080521:

         update tools/mtree, before running make build.          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
 20021219:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         CVS repository layout was changed.  See the following for details  
         if you are using (anonymous) cvs to update your tree.  20080303:
           Linker warnings are now fatal if $WARNS>0.
         http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html  
   20080126:
 20021219:          The posix_fadvise system call has been changed from an assembly
         install(1) had a '-N dbdir' option added, to specify an          stub, to a c file that calls an assembly stub. You need to
         alternate location to look up users & groups (instead          'rm -f posix_fadvise.* .depend' in the libc build directory to
         of the host system passwd(5) and group(5) databases).          avoid using the old assembly stub.
   
         The build system was modified to take advantage of  20071209:

 20021130:  20071115:
         fparseln(3) moved from libutil to libc.          The it(4) driver has been renamed to itesio(4) and the old port
         If building to DESTDIR=/, reinstall the includes          argument specified in the kernel configuration file is not valid
         and rebuild libc:          anymore. The itesio(4) driver now uses the Super I/O address port

         If using build.sh, "cd tools/compat && make clean"  
         before rebuilding the tools.  20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
 20021126:          You need to update any custom kernel configuration file you have
         The mk.conf(5) variable SYS_INCLUDE has been deprecated,          to remove any references to pccons (which includes removing the

         All header files, including <sys/*.h> are copied into          entries for the wscons driver.  See the GENERIC configuration file
         /usr/include.          for more details.
   
 20021121:  20070913:

         This means that libtool needs to be rebuilt once the          implementation was repaired.  From 20070529 to 20070911 racoon
         new libraries are installed.  The process of rebuilding          could not enumerate interfaces.  (These are noted because
         libtool will cause it to automatically notice the new          normal kernel/userspace version matching hygiene is not
         required files, but it *must* be rebuilt in order to          sufficient to avoid this problem.)  Ensure that both kernel
         do this.          and userland are from after 20070913.
   
         An out-of-date libtool will result in shared libraries  20070703:
         which lack _init() and _fini() routines, which means that          nbinstall has been renamed as it calls the target specific and
         their global contructors/destructors will not be invoked.          the logic to pass down STRIP from mk been removed.  This forces
           a re-installation of tools.
 20021121:  
         A bug related to how ARM ELF objects were tagged has been  20070422:
         corrected.          The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
         NetBSD ARM ELF uses the soft-VFP floating point model by          to userspace) namei() and lookup() directly check the emulation
         default.  However, the assembler lacked support for marking          root. One side effect is that absolute symlinks inside the emulated
         objects as using the VFP floating point format, and the          root file system will be relative to that file system - unless they

 20020906:  
         gehenna-devsw has been merged into the trunk. Need to update and  
         reinstall usr.sbin/config before building the kernel.  
   
 20020822:  
         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).

 20020605:  
         smmsp user/group has been added for sendmail.  
   
         Add the following into /etc/group:  
   
         smmsp:*:17:  
   
         and the following to /etc/master.passwd (via vipw):  
   
         smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin  
   
 20020515:  
         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:  
   
         sshd:*:16:  
   
         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).  
   
 20020426:  
         NBUILDJOBS obsoleted in favor of just using -j.  
   
 20020426:  
         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).  
   
 20020320:  
         <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.  
         Build and install at usr.bin/xinstall before the build.  
   
 20020319:  
         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.  
   
 20020311:  
         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).  
   
 20020223:  
         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.  
   
 20020118:  
         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:  
   
         ntpd:*:15:  
   
         and the following to /etc/master.passwd (via vipw):  
   
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin  
   
 20011207:  
         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)  
   
         gnu/lib/libgcc  
         gnu/lib/libstdc++  
   
         After this a snapshot will be able to be built.  
   
 20011201:  
         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)  
   
 20011128:  
         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.  
   
 20011030:  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  
   
 20011029:  
         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.  
   
 20011028:  
         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.  
   
 20011006:  
         /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  
   
 20011004:  
         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  
   
 20010915:  
         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  
         directories.  
   
 20010803:  
         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.  
   
 20010803:  
         (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]  
   
 20010731:  
         Bootloader update on ELF platforms.  DDB in kernels from before  
         this will be unable to read symbol tables provided by newer  
         bootloaders.  
   
 20010726:  
         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  
   
 20010718:  
         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.  
   
 20010628:  
         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.  
   
 20010226:  
         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:  
   
         named:*:14:  
   
         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.  
   
 20010219:  
         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.  
   
 20010204:  
         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  
   
 20010114:  
         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.  
   
 20010101:  
         bsd.subdir.mk committed 20001230 had a bug which caused  
         afterinstall targets to run too soon; update again.  
   
 20001230:  
         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.  
   
 20001019:  
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  
         directory.  
   
 20000929:  
         The following make directives are obsoleted.  
         MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA  
         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}.
