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. |

so it deal with the now present register prefix used in all |
20070412: |
the VAX assembly files. |
The pckbc driver on sgimips IP32 has been removed. Use macekbc |
|
instead. See the GENERIC32_IP3x kernel configuration for an |

the pthread library in sync, old threaded applications should |
gnu/lib/libstdc++ |
continue to work with an old or new kernel. Note that named(8) |
|
is the only threaded application in the base system. |
After this a snapshot will be able to be built. |

required in order for this to work properly. Make sure |
|
to build and install in usr.sbin/config before attempting |
20061009: |
to build a new kernel. |
The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer |
|
available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. |
20011030: |
|
libc/locale/wcstod.c now needs new lint(1). Update lint(1) |
20060814: |
before building libc. |
The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been |
|
withdrawn. Use vidcvideo and pckbd instead. See the GENERIC |
20011029: |
kernel configuration for an example. X servers from the last |
The new document BUILDING.mdoc (view with nroff | more, or |

if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed |
|
to ACPI_SCANPCI. Thanks to work from fvdl. |
Users building a USE_NEW_TOOLCHAIN system should read the |
|
BUILDING document for caveats. Generally, BUILDING supersedes |

by the new build system. |
For userlands with the old version of socket(2), make sure that |
|
your kernel has 'options COMPAT_30' set, or else 'bad system call' |
20011028: |
errors will result. |
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 |
|
|
|
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 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 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}. |
