 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.
   
 For a more detailed description see Makefile.  See also: BUILDING, build.sh, Makefile.
   
 Note that users of the new toolchain in many instances will not  
 experience the problems listed below because their host tools are  
 automatically generated for them.

 20011028:  20071209:
         src/etc/Makefile now needs install to be able to handle          The acpiec(4) driver has been split into two attachments. If you
         symlinks that point to nowhere. A bug in install that          get ACPI errors before the attachment, please update your kernel
         prevented this was corrected.          configuration file appropriately or see GENERIC for more details.
   
         Solution: update and reinstall usr.bin/xinstall  20071115:
         Better Solution: Use the new toolchain and it will just work          The it(4) driver has been renamed to itesio(4) and the old port
         for you.          argument specified in the kernel configuration file is not valid
           anymore. The itesio(4) driver now uses the Super I/O address port
 20011006:          rather than the EC address port. Please update your kernel
         /etc/mtree/NetBSD.dist has been updated to take advantage of          configuration file appropriately or see GENERIC for more details.
         absolute path support added to mtree(8). Older mtree(8)s don't  
         understand the format.  20071028:
           The pccons(4) driver has been removed from the NetBSD/shark port.
         Solution: update and reinstall usr.sbin/mtree          You need to update any custom kernel configuration file you have
           to remove any references to pccons (which includes removing the
 20011004:          now useless XSERVER option) and replace them with the correct
           entries for the wscons driver.  See the GENERIC configuration file
         Crunchgen has been updated to work via reach-over makefiles. Updating          for more details.

         is intended to make all the upgrade issues elsewhere in UPDATING          problems after 20070911 when the kernel's SIOCGIFCONF
         obsolete (stay tuned...).          implementation was repaired.  From 20070529 to 20070911 racoon
           could not enumerate interfaces.  (These are noted because

 20010915:  20070422:
         The new "ubcperf" code committed by Chuck Silvers removed          The way OS emulations lookup filenames inside the emulation root
         a header file, uvm/uvm_vnode.h.  There may be stale .depend          has been changed.  Rather than modify the pathname (and copy back
         files that still reference this file.          to userspace) namei() and lookup() directly check the emulation
           root. One side effect is that absolute symlinks inside the emulated
         Solution: "make cleandir && make dependall" in affected          root file system will be relative to that file system - unless they
         directories.          start /../ this is useful when the emulated root is a real install
           that has such links.

         grep.info is now built from grep.texi using makeinfo.  Since it          the emulated root.
         requires makeinfo v4.0, you need to install new texinfo before  
         building gnu/usr.bin/grep.  To install new texinfo, please follow  20070412:
         the instruction described in 20010726 entry.          The pckbc driver on sgimips IP32 has been removed. Use macekbc
           instead. See the GENERIC32_IP3x kernel configuration for an
 20010803:          example.
         (i386 only): i386 kernel now uses new instructions like  
         `fxsave' which old gas doesn't understand.  To build the  20070319:
         kernel successfuly, you need to build and install new gas          src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so

         this will be unable to read symbol tables provided by newer  
         bootloaders.  20070210:
           src/sys/sys/{sa.h,savar.h} were removed.

         make MKINFO=no dependall install          The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
 20010718:          kernel (version 4.99.10), then you also need a new pthread

         Enabled correct .init/.fini processing in crt0.  The way this          an old kernel, then you need the old pthread library
         was done was to change a -I directive to cc(1), which means          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         make(1) will have a stale dependency (it will be checking the          the pthread library in sync, old threaded applications should
         timestamp on the wrong "dot_init.h").          continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
         The symptom you will see is that new programs die with SIGSEGV  
         if you have a stale dependency.  20061214:
           Following the move of string_to_flags() and flags_to_string()
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          from the bin/ls/ sources to libutil, users doing UPDATE builds
         before starting your build.          will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
 20010628:                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         A construct was added to uvm_page.h that uncovered a bug                  as the installation images in distrib/
         in lint(1).  If you get a warning/error about a non-portable          in order to excise stale references to the old stat_flags.h header
         bitfield, update your lint(1) before proceeding.          file in the ls sources -- stat_flags.h has been removed.
   
 20010226:  20061108:
           The configure script used in the src/tools/gcc compiler has been
         Added named user/group to system. Need to hand add this in or builds          changed to indicate that our libc has ssp support built-in and
         will break as mtree aborts early.          does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
         To work around add by hand:  
   20061009:
         named:*:14:          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         to /etc/group and add:  
   20060814:
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         to master.passwd (use vipw for instance if doing by hand).          kernel configuration for an example.  X servers from the last
           few years should cope.
         Now a make build should progress.  
   20060703:
 20010219:          MPACPI is no more. We always configure PCI interrupts using ACPI
         get/setprogname() added. Any hostprog's that may use this will need          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         to be bootstrapped manually until the host system is current.          to ACPI_SCANPCI. Thanks to work from fvdl.
   
         Known problems: sys/arch/macppc/stand/fixcoff  20060627:
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to          socket(2) has changed, and its system call has been versioned.
                           CFLAGS and rebuilding should work)          For userlands with the old version of socket(2), make sure that
                         usr.sbin/mdsetimage - Build a static copy if          your kernel has 'options COMPAT_30' set, or else 'bad system call'
                           building a snapshot before fully bootstrapped.          errors will result.
   
 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}.  
   
 20000623:  
         MKCRYPTO and friends added to share/mk/bsd.own.mk.  
         'cd share/mk ; make install' needed before make build.
