 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.

         must update and reinstall usr.sbin/config before building a new  
         kernel.          If you have to load your kernel from a file system which is not of
           the same type as the root file system, you have to load the necessary
 20021009:          file system module manually on the boot prompt or in the boot.cfg file.
         A new attribute dependency syntax was introduced to config(8),

           The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
 20020917:          from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)

             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which          won't work correctly. The following sequence of commands:
                 there is no working in-tree toolchain (hppa, ns32k, sh5,  
                 x86_64).            $ (cd sys/sys/ && nbmake-$arch includes)
             -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the            $ (cd sbin/drvctl/ && nbmake-$arch clean)
                 root of an external toolchain (e.g. /usr/local/gnu).  This            $ (cd sbin/drvctl/ && nbmake-$arch all)
                 enables the cross-build framework even for TOOLCHAIN_MISSING  
                 platforms.          leaves new drvctl utility in sbin/drvctl build directory.

         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)  20071209:

 20020426:          The pccons(4) driver has been removed from the NetBSD/shark port.
         NBUILDJOBS obsoleted in favor of just using -j.          You need to update any custom kernel configuration file you have
           to remove any references to pccons (which includes removing the
 20020426:          now useless XSERVER option) and replace them with the correct

         the problems identified.  
         This should make it much easier to upgrade a system's  20070913:
         configuration from earlier systems (as far back as NetBSD 1.5).          A latent bug in dhclient/dhcpd that caused it to be unable to
           enumerate interfaces was fixed.  The bug began to cause
 20020320:          problems after 20070911 when the kernel's SIOCGIFCONF
         <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.          implementation was repaired.  From 20070529 to 20070911 racoon
         Build and install at usr.bin/xinstall before the build.          could not enumerate interfaces.  (These are noted because

         newer than November 2001 when you upgrade the kernel.  20070703:
           nbinstall has been renamed as it calls the target specific and

         ssh configuration files were moved from /etc to /etc/ssh.  Beware          a re-installation of tools.
         if you restart your machine from remote.  Note that sshd.conf needs  
         to be changed (due to the use of "/etc" inside).  20070422:
           The way OS emulations lookup filenames inside the emulation root
 20020223:          has been changed.  Rather than modify the pathname (and copy back
         Users of the VAX port will need to rebuild and install gas          to userspace) namei() and lookup() directly check the emulation

 20011028:  20060703:
         src/etc/Makefile now needs install to be able to handle          MPACPI is no more. We always configure PCI interrupts using ACPI
         symlinks that point to nowhere. A bug in install that          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         prevented this was corrected.          to ACPI_SCANPCI. Thanks to work from fvdl.
   
         Solution: update and reinstall usr.bin/xinstall  20060627:
         Better Solution: Use the new toolchain and it will just work          socket(2) has changed, and its system call has been versioned.
         for you.          For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
 20011006:          errors will result.
         /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}.
