Critical utilities for the system and the superuser.
usr.bin/
Not-so critical utilities for the system and users.
usr.sbin/
Not-so critical utilities for the system and the superuser.
common/
Sources shared between kernel and userland.
dist/
Utilities. Every utility has its own subdirectory, where its source
and Makefile are located.
include/
Include headers. Every group of header files has its own subdirectory,
where it and its Makefile are located.
lib/
Libraries. Every library has its own subdirectory, where it and its
Makefile are located.
compat/
A framework to (re)build the libraries shipped with
NetBSD for different ABI than the default for that
platform.
compat/<arch1>/<arch2>/
Every compat/<arch1>/<arch2>/
directory contains a Makefile and a makefile fragment for building an
<arch2> compat libraries for
<arch1>. E. g.,
compat/amd64/i386/ is where the 32-bit compat
libraries for the amd64 port are being built.
compatsubdir.mk
The list of subdirectories (the libraries and ld.elf_so) to build with
this ABI.
archdirs.mk
The list of subdirectories for each port.
Makefile.compat
The basic framework to force the right paths for library and ld.elf_so
linkage.
dirshack/Makefile
A hack to get objdirs created timely.
crypto/
Cryptographic source, which may have import or export restrictions.
dist/
Original sources. This is deprecated;
crypto/external/ should be used instead.
external/
Original sources, grouped by license, and then package per license.
crypto/external/<license>/<package>/dist/
contain original sources for given package; other directories contain
Makefiles and given package's config files.
dist/
Unmodified sources from third parties. This is deprecated;
external/ should be used instead.
distrib/
Tools and data-files for making distributions.
<arch>/
Architecture-specific files, grouped by image type. E. g.,
distrib/<arch>/floppies/ contains
Makefiles for making images for various types of floppies;
<arch>/ramdisk/ contains makefiles for
making ramdisks etc.
cdrom/
Was used to create bootable CD images. This is deprecated;
build.sh ´s
iso-image target should be used instead.
common/
Common files for images generation.
miniroot/
Files for miniroot.
notes/<arch>
Architecture-specific parts of release notes.
sets/
Scripts for making file sets.
utils/
Utilities for installation ramdisk.
doc/
Development documentation files: changelogs, build readmes etc.
doc/roadmaps/ contains roadmaps.
etc/
Default configuration files to be put into /etc.
etc/etc.<arch>/
Architecture-specific config files.
external/
Unmodified sources from third parties, grouped by license. They are built
with so-called "reachover" Makefiles which can be found in
src/*bin/ hierarchies. Every
external/<license>/<package>/ may
contain:
dist/
Unmodified third party source for a given package
bin/
usr.bin/
usr.sbin/
etc.
Such subdirectories contain reachover Makefiles, README's and various
import helper scripts. E. g.,
external/public-domain/ contains sources
licensed under Public Domain license;
external/public-domain/sqlite/dist/ contains
original sources;
external/public-domain/sqlite/bin/,
external/public-domain/sqlite/lib/ and
external/public-domain/sqlite/ itself contain
reachover Makefiles.
extsrc/
Optional developer-provided sources that are built if
MKEXTSRC=yes, as a way to include extra components
in the build.
games/
Sources for utilities/files in /usr/games; each
utility has its own subdirectory, where its sources and Makefiles are
located.
gnu/
Sources licensed under GNU GPL. This is deprecated;
external/gpl2/ or
external/gpl3/ should be used instead.
gnu/dists contains the original GNU sources plus
changes that were submitted to maintainers and that are not yet published.
Other folders contain files that are never expected to be submitted to the
FSF (reachover Makefiles, etc.)
include/
Files to be put into /usr/include.
lib/
Source for libraries in /usr/lib and some scripts
for them. Every directory contains source for given library and
Makefiles.
libexec/
Source for utilities in /usr/libexec. Every
directory contains source for given utility and Makefiles.
regress/
Various regression tests in /usr/tests. This is
deprecated; most tests are being migrated into
tests/ once they are migrated to the
atf(7) test framework.
rescue/
Makefiles for copying utilities to /rescue.
share/
Source for utilities/files in /usr/share. Every
utility has its own subdirectory, where its source and Makefile are
located.
sys/
Kernel source.
altq/
Network packet alternate queueing.
arch/
Files to specific hardware platforms.
coda/
Coda file system driver.
compat/
Support for older version NetBSD binaries and
non-NetBSD binaries.
conf/
Misc files for building kernel.
crypto/
Crypt algorithms used by IPsec.
ddb/
Client code for local kernel debugger.
dev/
Device drivers.
dist/
Parent directory for the OpenBSD packet filter
pf(4).
Source for several standalone programs that aren't used by
NetBSD currently.
sys/
Header files that get installed into
/usr/include/sys.
ufs/
UFS file system driver.
uvm/
Virtual memory manager.
tests/
Source for test programs in /usr/tests. These
tests use the atf(7) test
framework. For library routines, including system calls, the directory
structure of the tests should follow the directory structure of the real
source tree. For instance, interfaces available via the C library should
follow: src/lib/libc/gen ->src/tests/lib/libc/gen,
src/lib/libc/sys ->src/tests/lib/libc/sys, etc. Equivalently, all
tests for userland utilities should try to follow their location in the
source tree. If this can not be satisfied, the tests for a utility should
be located under the directory to which the utility is installed. Thus, a
test for env(1) should go to
src/tests/usr.bin/env. Likewise, a test for
tcpdump(8) should be in
src/tests/usr.sbin/tcpdump, even though the source
code for the program is located under
src/external.
tools/
Reachover build structure for the host build tools. Every utility has its
own directory, where its Makefile is located.
x11/
Reachover build structure for X11R7; the source is in
X11SRCDIR. The directory structure copies the
system´s; every directory contains a Makefile.
