Recent changes: ^^^^^^^^^^^^^^^ -20011028: - src/etc/Makefile now needs install to be able to handle - symlinks that point to nowhere. A bug in install that - prevented this was corrected. - - Solution: update and reinstall usr.bin/xinstall - 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 - -20010922: - The new toolchain is enabled on i386. This new build method - is intended to make all the upgrade issues elsewhere in UPDATING - obsolete (stay tuned...). - - i386 platform builds must now set TOOLDIR in mk.conf or the - environment in order to build the system. This is a pathname - where host build tools will be installed, and must NOT be - the same as src/tools. - - (Optionally, USETOOLS=no can be set in the environment if you - wish to avoid using the separate host toolchain for building a - subtree. Otherwise, this will default to "yes" automatically.) - -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 successfuly, you need to build and install new gas - (gnu/usr.bin/gas.new), or (temporarily) comment out - "options I686_CPU" from your kernel configuration until you - rebuilt your userland (and got a new gas). - -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 hostprog's 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}. - -20000623: - MKCRYPTO and friends added to share/mk/bsd.own.mk. - 'cd share/mk ; make install' needed before make build. - +20080126: + The posix_fadvise system call has been changed from an assembly + stub, to a c file that calls an assembly stub.

Rather than modify the pathname (and copy back + to userspace) namei() and lookup() directly check the emulation + root. One side effect is that absolute symlinks inside the emulated + root file system will be relative to that file system - unless they + start /../ this is useful when the emulated root is a real install + that has such links. + This might affect symlinks that have been added to reference outside + the emulated root. + +20070412: + The pckbc driver on sgimips IP32 has been removed.

If you boot with a new + kernel (version 4.99.10), then you also need a new pthread + library (/usr/lib/libpthread.so.0.7).

You'll need to + make clean in src/tools/gcc first to rebuild the compiler. + +20061009: + The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer + available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. + +20060814: + The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been + withdrawn. Use vidcvideo and pckbd instead. See the GENERIC + kernel configuration for an example. X servers from the last + few years should cope. + +20060703: + MPACPI is no more. We always configure PCI interrupts using ACPI + if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed + to ACPI_SCANPCI. Thanks to work from fvdl. + +20060627: + socket(2) has changed, and its system call has been versioned. + For userlands with the old version of socket(2), make sure that + your kernel has 'options COMPAT_30' set, or else 'bad system call' + errors will result.
