 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

 20031111:  20090110:
         A newer mkdep is needed.  Error noting that is          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
                 cc: Ambiguous abbreviation --          1. Make sure your kernel has COMPAT_50 in it. Build and install.
              This is needed even in the MODULAR kernel because there is
 20031008:             conditionally compiled code in rtsock.c.
         /usr/include/sys/disklabel_mbr.h was removed.          2. make sure build.sh completes and the binaries in a chroot work
         It's necessary to "make cleandir" to ensure that             before installing.
         the dependencies will be rebuilt correctly.          3. If you don't use build.sh and you build directly to root, and
              your build breaks in the middle, don't despair. Make sure headers
 20030906:             are installed properly, and start building libraries first libc
         With the addition of siginfo support the old signal trampoline             and libutil, install them and then continue building all the
         code has been deprecated to COMPAT_16. Make sure that your running             libraries in src/lib and src/gnu/lib and install them. Once
         kernel has COMPAT_16 enabled before building userland.             the new libraries are installed, you can restart the build.
           4. If you compile packages and you notice link time warnings,
 20030801:             rebuild the required packages to update their shared libraries.
         With the new openssl, there is some header and library shuffling.             Any package you rebuild will require rebuilding all the packages
         rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \             that depend on it.
         /usr/lib/libdes* before building.          5. Next time you run pwd_mkdb with the new binary, the file
              will be upgraded and it will not be backwards compatible.
 20030703:          6. The utmpx/wtmpx files have been versioned, and there is
         Texinfo was updated to 4.6.  To avoid failures when trying to             a heuristic for utmp. You are better off removing the

         (untested).  20081205:
           If you build with MKX11=no, you should remove /etc/rc.d/xdm and
 20030516:          /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc

         mountd got restarted because it freed memory that had already  20081122:
         been freed. This has been fixed and the kernel checks          On i386, various kernel options(4) in GENERIC including
         export addresses very strictly. If you upgrade your kernel,          file systems have been disabled and moved into kernel modules.

           - build and install kernel modules from src/sys/modules
 20030402:  
         The superblock layout for FFS was changed.  If you have 1.6          - install the latest bootloader, which will load a module
         fsck binaries, they will signal a fatal superblock mismatch            for the file system from which the kernel is loaded automatically
         with the first alternate, because they compare too many  
         fields (even ones that aren't useful).  If possible, upgrade          If you have to load your kernel from a file system which is not of

   20080731:
 20030117:          WAPBL (metadata journaling support) has been added, but at this
         Texinfo was updated to 4.3.  To avoid failures when trying to          time isn't backwards compatible with pre-WAPBL aware kernels
         build the included texinfo files, do:          and userland (fsck_ffs in particular).  Please make sure you
           don't use a journaled filesystem with an older kernel/userland,
         cd src/gnu/usr.bin/texinfo          especially an uncleanly mounted journaled filesystem.  WAPBL
         make MKINFO=no dependall install          also requires the super block to be in the UFS2 format.  You
           can use fsck_ffs -c 4 to update the superblock format.
 20021223:  
         The METALOG format changed slightly, to remove the leading  20080721:
         "${DESTDIR}" from path names.          Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
         This only affects people building with UNPRIVED.          isn't defined.
         For complete safety, remove the DESTDIR entirely and  
         update tools/mtree, before running make build.  20080531:
           The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
 20021219:          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
         CVS repository layout was changed.  See the following for details          utility needs to be rebuilt and reinstalled as older binaries

             $ (cd sbin/drvctl/ && nbmake-$arch clean)
 20021219:            $ (cd sbin/drvctl/ && nbmake-$arch all)

         alternate location to look up users & groups (instead          leaves new drvctl utility in sbin/drvctl build directory.
         of the host system passwd(5) and group(5) databases).  
   20080503:
         The build system was modified to take advantage of          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         this option (using ${NETBSDSRCDIR}/etc), so if you  
         use USETOOLS==no, you may have to rebuild and  20080521:
         reinstall usr.bin/xinstall first.          For a while, unprivileged UPDATE builds would fail to
           succeed at the checkflist stage, complaining that
 20021130:          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         fparseln(3) moved from libutil to libc.          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
         If building to DESTDIR=/, reinstall the includes          If you already hit this problem, update the .mk file,
         and rebuild libc:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
                 make includes  
                 make do-lib-libc  20080303:
         If using build.sh, "cd tools/compat && make clean"          Linker warnings are now fatal if $WARNS>0.
         before rebuilding the tools.  
   20080126:
 20021126:          The posix_fadvise system call has been changed from an assembly

         /usr/include.  
   20071209:
 20021121:          The acpiec(4) driver has been split into two attachments. If you
         The C run-time support files crtbegin.o and crtend.o          get ACPI errors before the attachment, please update your kernel
         (and their companions crtbeginS.o and crtendS.o) were          configuration file appropriately or see GENERIC for more details.
         split up, with new crti.o and crtn.o files resulting.  
         This means that libtool needs to be rebuilt once the  20071115:
         new libraries are installed.  The process of rebuilding          The it(4) driver has been renamed to itesio(4) and the old port
         libtool will cause it to automatically notice the new          argument specified in the kernel configuration file is not valid
         required files, but it *must* be rebuilt in order to          anymore. The itesio(4) driver now uses the Super I/O address port
         do this.          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
         An out-of-date libtool will result in shared libraries  
         which lack _init() and _fini() routines, which means that  20071028:
         their global contructors/destructors will not be invoked.          The pccons(4) driver has been removed from the NetBSD/shark port.
           You need to update any custom kernel configuration file you have

         corrected.          entries for the wscons driver.  See the GENERIC configuration file
           for more details.
         NetBSD ARM ELF uses the soft-VFP floating point model by  
         default.  However, the assembler lacked support for marking  20070913:
         objects as using the VFP floating point format, and the          A latent bug in dhclient/dhcpd that caused it to be unable to

         to the assembler.          problems after 20070911 when the kernel's SIOCGIFCONF
           implementation was repaired.  From 20070529 to 20070911 racoon
         Unfortunately, this means that the linker will now consider          could not enumerate interfaces.  (These are noted because
         old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be          normal kernel/userspace version matching hygiene is not
         incompatible with new (properly marked) objects.          sufficient to avoid this problem.)  Ensure that both kernel
           and userland are from after 20070913.
         The problem will only manifest itself if you attempt to compile  
         a new program using the fixed toolchain, and link that program  20070703:

         The only work-around for the problem is to recompile all of  20070422:

         reinstall usr.sbin/config before building the kernel.  
   20060814:
 20020822:          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been

         To ensure that these are built statically linked (no matter  
         what the setting of LDSTATIC is), use a crunchgen(1) built  20060703:
         from sources newer than 20020820 (see the next entry).          MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
 20020820:          to ACPI_SCANPCI. Thanks to work from fvdl.
         crunchgen(1) changed to ensure that the generated program  
         is statically linked.  20060627:
           socket(2) has changed, and its system call has been versioned.
         Solution: update and reinstall usr.bin/crunch          For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
 20020605:          errors will result.
         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}.
