 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

         To ensure that these are built statically linked (no matter  20081122:
         what the setting of LDSTATIC is), use a crunchgen(1) built          On i386, various kernel options(4) in GENERIC including

         Solution: update and reinstall usr.bin/crunch          - install the latest bootloader, which will load a module

         Add the following into /etc/group:

         and the following to /etc/master.passwd (via vipw):          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin          needed -- lint must be disabled temporarily, e.g.:

         also /var/chroot/sshd directory needs to be present (digged as a part of

           Following the move of string_to_flags() and flags_to_string()
 20010726:          from the bin/ls/ sources to libutil, users doing UPDATE builds
         Texinfo was updated to 4.0.  To avoid failures when trying to          will need to do a "make cleandir" in
         build the included texinfo files, do:                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
                   bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         cd src/gnu/usr.bin/texinfo                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         make MKINFO=no dependall install                  as the installation images in distrib/
           in order to excise stale references to the old stat_flags.h header
 20010718:          file in the ls sources -- stat_flags.h has been removed.
         Enabled correct .init/.fini processing in crt0.  The way this  
         was done was to change a -I directive to cc(1), which means  20061108:
         make(1) will have a stale dependency (it will be checking the          The configure script used in the src/tools/gcc compiler has been
         timestamp on the wrong "dot_init.h").          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
         The symptom you will see is that new programs die with SIGSEGV          make clean in src/tools/gcc first to rebuild the compiler.
         if you have a stale dependency.  
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
         before starting your build.          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
 20010628:  20060814:
         A construct was added to uvm_page.h that uncovered a bug          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         in lint(1).  If you get a warning/error about a non-portable          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         bitfield, update your lint(1) before proceeding.          kernel configuration for an example.  X servers from the last
           few years should cope.
         Added named user/group to system. Need to hand add this in or builds  20060703:
         will break as mtree aborts early.          MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         To work around add by hand:          to ACPI_SCANPCI. Thanks to work from fvdl.
         named:*:14:  20060627:
           socket(2) has changed, and its system call has been versioned.
         to /etc/group and add:          For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin          errors will result.
         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}.
