 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.

         Groff was update to 1.19; it's probably necessary to do          unless they are rebuilt.  If you are building with MKUPDATE=yes,

         mountd got restarted because it freed memory that had already  20100522:
         been freed. This has been fixed and the kernel checks          private section of <ctype.h> was splitted, and now mklocale(1)
         export addresses very strictly. If you upgrade your kernel,          include ctype_local.h, so you have to make cleandir in tools/mklocale.
         make sure you also upgrade mountd, because if your export  
         file contains lines with an old inet4 address syntax (i.e.  20100520:
         a.b.c or a.b or a), they will get rejected by the new kernel.          The location of the xkb compiled descriptions has changed. Please
           remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
 20030402:  
         The superblock layout for FFS was changed.  If you have 1.6  20100222:
         fsck binaries, they will signal a fatal superblock mismatch          The shared objects file extension has been changed from .so to
         with the first alternate, because they compare too many          .pico, in order to avoid conflicts with shared libraries names

         None of this signals actual filesystem damage.

 20021223:  
         The METALOG format changed slightly, to remove the leading  20090718:

         ntpd:*:15:          The way OS emulations lookup filenames inside the emulation root
           has been changed.  Rather than modify the pathname (and copy back
         and the following to /etc/master.passwd (via vipw):          to userspace) namei() and lookup() directly check the emulation

           instead. See the GENERIC32_IP3x kernel configuration for an
         Build a new toolchain (i.e. build.sh -t)          example.
         Use the new toolchain to build and install natively (i.e. /usr/lib)  
   20070319:
         gnu/lib/libgcc          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
         gnu/lib/libstdc++          on many platforms due to incorrect flags settings.  If you

         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links  20070209:
         against the new libgcc.a)          The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
 20011128:          kernel (version 4.99.10), then you also need a new pthread
         Kernel config information was changed to use defflag in          library (/usr/lib/libpthread.so.0.7).  If you boot with
         the various "files" files.  Bug fixes to config(8) are          an old kernel, then you need the old pthread library
         required in order for this to work properly.  Make sure          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         to build and install in usr.sbin/config before attempting          the pthread library in sync, old threaded applications should
         to build a new kernel.          continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
 20011030:  
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)  20061214:
         before building libc.          Following the move of string_to_flags() and flags_to_string()
           from the bin/ls/ sources to libutil, users doing UPDATE builds
 20011029:          will need to do a "make cleandir" in
         The new document BUILDING.mdoc (view with nroff | more, or                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         see pre-generated .txt and .html versions) describes the build                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         build process, are intended in the long run to replace this                  as the installation images in distrib/
         manual update log.          in order to excise stale references to the old stat_flags.h header
           file in the ls sources -- stat_flags.h has been removed.
         Users building a USE_NEW_TOOLCHAIN system should read the  
         BUILDING document for caveats.  Generally, BUILDING supersedes  20061108:
         UPDATING for these systems, as tool updating is taken care of          The configure script used in the src/tools/gcc compiler has been
         by the new build system.          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
 20011028:          make clean in src/tools/gcc first to rebuild the compiler.
         src/etc/Makefile now needs install to be able to handle  
         symlinks that point to nowhere. A bug in install that  20061009:
         prevented this was corrected.          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         Solution: update and reinstall usr.bin/xinstall  
         Better Solution: Use the new toolchain and it will just work  20060814:
         for you.          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
 20011006:          kernel configuration for an example.  X servers from the last
         /etc/mtree/NetBSD.dist has been updated to take advantage of          few years should cope.
         absolute path support added to mtree(8). Older mtree(8)s don't  
         understand the format.  20060703:
           MPACPI is no more. We always configure PCI interrupts using ACPI
         Solution: update and reinstall usr.sbin/mtree          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
 20011004:  
         Crunchgen has been updated to work via reach-over makefiles. Updating  20060627:
         is suggested before running a snapshot build          socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
 20010915:          your kernel has 'options COMPAT_30' set, or else 'bad system call'
         The new "ubcperf" code committed by Chuck Silvers removed          errors will result.
         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}.
