 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.

              will be upgraded and it will not be backwards compatible.
         The build system was modified to take advantage of          6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
         this option (using ${NETBSDSRCDIR}/etc), so if you             lastlogx(5)) have been versioned, and there is a heuristic
         use USETOOLS==no, you may have to rebuild and             for utmp. You are better off removing the old files after
         reinstall usr.bin/xinstall first.             upgrading.  The automated clearing of /var/run during
              boot, and the automated rotating of files in /var/log by

         including the optional "SYS_INCLUDE=symlinks" support.  
         All header files, including <sys/*.h> are copied into  20081219:

         do this.  
   20081122:
         An out-of-date libtool will result in shared libraries          On i386, various kernel options(4) in GENERIC including
         which lack _init() and _fini() routines, which means that          file systems have been disabled and moved into kernel modules.
         their global contructors/destructors will not be invoked.          Before trying a new GENERIC kernel, you have to prepare the
           following files as well as a new GENERIC kernel:
 20021121:  
         A bug related to how ARM ELF objects were tagged has been          - build and install kernel modules from src/sys/modules
         corrected.

         Unfortunately, this means that the linker will now consider  20080827:

           which results in false errors reported by lint(1).
         The problem will only manifest itself if you attempt to compile          Since this breaks the libc build itself, manual help is

 20021011:  
         Systrace has been improved to support privilege elevation.          One way to find affected pkgsrc packages:
         Updating the kernel requires the userland part of systrace  
         to be rebuilt.            $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO

         Several changes have been made to the autoconfiguration  
         framework.  Users must update and reinstall usr.sbin/config  20080531:
         before building a new kernel.          The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed

         The i386mp branch has been merged.  To compile a kernel, users          won't work correctly. The following sequence of commands:

         To ensure that these are built statically linked (no matter          argument specified in the kernel configuration file is not valid
         what the setting of LDSTATIC is), use a crunchgen(1) built          anymore. The itesio(4) driver now uses the Super I/O address port
         from sources newer than 20020820 (see the next entry).          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
 20020820:

           You need to update any custom kernel configuration file you have
         Solution: update and reinstall usr.bin/crunch          to remove any references to pccons (which includes removing the
           now useless XSERVER option) and replace them with the correct

           A latent bug in dhclient/dhcpd that caused it to be unable to
         smmsp:*:17:          enumerate interfaces was fixed.  The bug began to cause
           problems after 20070911 when the kernel's SIOCGIFCONF
         and the following to /etc/master.passwd (via vipw):          implementation was repaired.  From 20070529 to 20070911 racoon

           The way OS emulations lookup filenames inside the emulation root
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          has been changed.  Rather than modify the pathname (and copy back

 20020223:  20070209:
         Users of the VAX port will need to rebuild and install gas          The threading model was changed when the newlock2 branch
         so it deal with the now present register prefix used in all          was merged to NetBSD-current.  If you boot with a new
         the VAX assembly files.          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
 20020118:          an old kernel, then you need the old pthread library
         ntpd user/group has been added.  Need to hand add this in or builds          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         will break as mtree aborts early.          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
         Add the following into /etc/group:          is the only threaded application in the base system.
   
         ntpd:*:15:  20061214:
           Following the move of string_to_flags() and flags_to_string()
         and the following to /etc/master.passwd (via vipw):          from the bin/ls/ sources to libutil, users doing UPDATE builds
           will need to do a "make cleandir" in

         reloc errors from the toolchain groff binary this means your native          in order to excise stale references to the old stat_flags.h header
         toolchain has some broken C++ bits.          file in the ls sources -- stat_flags.h has been removed.
   
         To fix:  20061108:
           The configure script used in the src/tools/gcc compiler has been
         Build a new toolchain (i.e. build.sh -t)          changed to indicate that our libc has ssp support built-in and
         Use the new toolchain to build and install natively (i.e. /usr/lib)          does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
         gnu/lib/libgcc  
         gnu/lib/libstdc++  20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
         After this a snapshot will be able to be built.          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
   
 20011201:  20060814:
         In order for a sparc64 build to work you must have a working awk. If          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         you've built and installed a system with the new toolchain up to this          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         point you do not have a working awk as its ability to do floating          kernel configuration for an example.  X servers from the last
         point is broken.          few years should cope.
   
         To build:  20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
         remake and install gnu/lib/libgcc          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          to ACPI_SCANPCI. Thanks to work from fvdl.
         against the new libgcc.a)  
   20060627:
 20011128:          socket(2) has changed, and its system call has been versioned.
         Kernel config information was changed to use defflag in          For userlands with the old version of socket(2), make sure that
         the various "files" files.  Bug fixes to config(8) are          your kernel has 'options COMPAT_30' set, or else 'bad system call'

         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}.
