 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

         If you're attempting to build a snapshot on sparc64 and are getting          cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
         reloc errors from the toolchain groff binary this means your native          rebuild of object files that might have been built
         toolchain has some broken C++ bits.          incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
         To fix:  
   20070210:
         Build a new toolchain (i.e. build.sh -t)          src/sys/sys/{sa.h,savar.h} were removed.
         Use the new toolchain to build and install natively (i.e. /usr/lib)            find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
                 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
         gnu/lib/libgcc          will allow dependencies on those files to get get rebuilt
         gnu/lib/libstdc++  
   20070209:
         After this a snapshot will be able to be built.          The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
 20011201:          kernel (version 4.99.10), then you also need a new pthread
         In order for a sparc64 build to work you must have a working awk. If          library (/usr/lib/libpthread.so.0.7).  If you boot with
         you've built and installed a system with the new toolchain up to this          an old kernel, then you need the old pthread library
         point you do not have a working awk as its ability to do floating          (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
         point is broken.          the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
         To build:          is the only threaded application in the base system.
   
         remake and install gnu/lib/libgcc  20061214:
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          Following the move of string_to_flags() and flags_to_string()
         against the new libgcc.a)          from the bin/ls/ sources to libutil, users doing UPDATE builds
           will need to do a "make cleandir" in
 20011128:                  tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
         Kernel config information was changed to use defflag in                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         the various "files" files.  Bug fixes to config(8) are                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         required in order for this to work properly.  Make sure                  as the installation images in distrib/
         to build and install in usr.sbin/config before attempting          in order to excise stale references to the old stat_flags.h header
         to build a new kernel.          file in the ls sources -- stat_flags.h has been removed.
   
 20011030:  20061108:
         libc/locale/wcstod.c now needs new lint(1). Update lint(1)          The configure script used in the src/tools/gcc compiler has been
         before building libc.          changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
 20011029:          make clean in src/tools/gcc first to rebuild the compiler.
         The new document BUILDING.mdoc (view with nroff | more, or  
         see pre-generated .txt and .html versions) describes the build  20061009:
         procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN          The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer

         manual update log.  
   20060814:
         Users building a USE_NEW_TOOLCHAIN system should read the          The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         BUILDING document for caveats.  Generally, BUILDING supersedes          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         UPDATING for these systems, as tool updating is taken care of          kernel configuration for an example.  X servers from the last
         by the new build system.          few years should cope.
   
 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}.
