 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.

         make MKINFO=no dependall install          The location of the xkb compiled descriptions has changed. Please
           remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
 20030630:  
         Groff was update to 1.19; it's probably necessary to do  
                 cd share/mk && make install  20100222:
                 cd src/gnu/usr.bin/groff          The shared objects file extension has been changed from .so to
                 make MKMAN=no dependall install          .pico, in order to avoid conflicts with shared libraries names
         (untested).          libXX.so.  All now stale regular .so files can be removed from
           your object directories.
 20030516:  
         Due to bugs in the export handling code, invalid export lines  20100204:

         information.  20090709:
           Native Xorg was upgraded again.  Builds will probably fail again
 20030117:          without a clean objdir, at least for src/external/mit/xorg.
         Texinfo was updated to 4.3.  To avoid failures when trying to  
         build the included texinfo files, do:  20090616:

         The METALOG format changed slightly, to remove the leading  
         "${DESTDIR}" from path names.  20090501:

         http://mail-index.netbsd.org/netbsd-announce/2002/12/19/0000.html          The i386 port was switched to i486 default toolchain.  This requires
           cleaning your src/tools directory and $TOOLDIR and rebuilding them.

           to avoid using the old assembly stub.
         The build system was modified to take advantage of

         If you're attempting to build a snapshot on sparc64 and are getting  
         reloc errors from the toolchain groff binary this means your native  20070210:
         toolchain has some broken C++ bits.          src/sys/sys/{sa.h,savar.h} were removed.

         To fix:                | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
         Build a new toolchain (i.e. build.sh -t)  
         Use the new toolchain to build and install natively (i.e. /usr/lib)  20070209:
           The threading model was changed when the newlock2 branch
         gnu/lib/libgcc          was merged to NetBSD-current.  If you boot with a new
         gnu/lib/libstdc++          kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
         After this a snapshot will be able to be built.          an old kernel, then you need the old pthread library
           (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and

         In order for a sparc64 build to work you must have a working awk. If          continue to work with an old or new kernel.  Note that named(8)
         you've built and installed a system with the new toolchain up to this          is the only threaded application in the base system.
         point you do not have a working awk as its ability to do floating  
         point is broken.  20061214:
           Following the move of string_to_flags() and flags_to_string()
         To build:          from the bin/ls/ sources to libutil, users doing UPDATE builds
           will need to do a "make cleandir" in
         remake and install gnu/lib/libgcc                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         against the new libgcc.a)                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
                   as the installation images in distrib/
 20011128:          in order to excise stale references to the old stat_flags.h header
         Kernel config information was changed to use defflag in          file in the ls sources -- stat_flags.h has been removed.
         the various "files" files.  Bug fixes to config(8) are  
         required in order for this to work properly.  Make sure  20061108:
         to build and install in usr.sbin/config before attempting          The configure script used in the src/tools/gcc compiler has been
         to build a new kernel.          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
 20011030:          make clean in src/tools/gcc first to rebuild the compiler.
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  
         before building libc.  20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
 20011029:          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         The new document BUILDING.mdoc (view with nroff | more, or  
         see pre-generated .txt and .html versions) describes the build  20060814:
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         build process, are intended in the long run to replace this          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         manual update log.          kernel configuration for an example.  X servers from the last
           few years should cope.
         Users building a USE_NEW_TOOLCHAIN system should read the  
         BUILDING document for caveats.  Generally, BUILDING supersedes  20060703:
         UPDATING for these systems, as tool updating is taken care of          MPACPI is no more. We always configure PCI interrupts using ACPI
         by the new build system.          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
 20011028:  
         src/etc/Makefile now needs install to be able to handle  20060627:
         symlinks that point to nowhere. A bug in install that          socket(2) has changed, and its system call has been versioned.
         prevented this was corrected.          For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
         Solution: update and reinstall usr.bin/xinstall          errors will result.
         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}.
