Patch the build script and toolchain to allow passing through
HOST_CPPFLAGS, HOST_CXXFLAGS, but not LIBRARY_PATH because it breaks

but /bin/sh do not exist. In many cases, support for HOST_CPPFLAGS
was incomplete. From Ryan Sundberg

Fix building libprop as a host tool library on platforms that don't have

- Include rb.c in libnbcompat, and provide a nbcompat sys/rbtree.h

anything else, and pull in nbtool_config.h from there.

Tested by simulating such a host system by renaming the host's
<sys/rbtree.h> out of the way (which reproduced the build failure)
and verifying that the host-tool installboot contained the rb_*
functions in its own .text segment.

Create a new bsd.hostinit.mk file and put the build definitions for all host

Remove the Makefile.inc files that contained these same settings, and
remove the settings from Makefile.host

PR/53238: Robert Elz: Disable MKREPRO in tools; the host compiler might
not support the necessary options. This is done thusly:

1. Set MKREPRO=no in Makefile.host. This handles all the Makefiles that
use it and don't include bsd.own.mk.
2. Create Makefile.inc and set MKREPRO=no in it. Change the Makefiles that
include bsd.own.mk, to include bsd.init.mk which includes Makefile.inc
first. This will also allow us to control other tools options from a
single location if we need to.

Use a "find | while read" loop to install all *.h files anywhere

a subdirectory) were not installed.

Make tools/compat/Makefile install the library in
${TOOLDIR}/lib/libnbcompat.a, install the include files in
${TOOLDIR}/include/compat/**, and install defs.mk in
${TOOLDIR}/share/compat/defs.mk. Previously, nothing from
tools/compat was installed under TOOLDIR.

Adjust tools/compat/Makefile to use an uninstalled copy of
host-mkdep from the .OBJDIR of tools/host-mkdep, and an uninstalled

before tools/host-mkdep is installed; and to be installed after
tools/binstall is built but before tools/binstall is installed.

Teach tools/compat/Makefile to use an uninstalled copy of host-mkdep

Put common/lib/libc/stdlib into .PATH. From Hisashi T Fujinaka.

Some tools need efuns.

Don't remove files that are needed for a build after make clean. Before
'make clean; make' failed in tools because necessary configure generated
files were removed. The failure manifested itself with string_to_flags
being undefined in binstall.

Redo previous differently: use AH_TOP and AH_BOTTOM macros to insert
header and footer into nbtool_config.h.in directly.

Make using autoheader easier:
split off the autogenerated file into nbtool_config_internal.h,
and let nbtool_config.h be a file with the proper wrappers.

This way you can just change configure.ac, run autoconf and autoheader,
verify the result, and commit, but don't have to edit nbtool_config*in
manually every time.

Add heapsort to libnbcompat

Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

branches: 1.28.2;
Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

Must add "configure.lineno" to CLEANFILES after updating to autoconf 2.57.

Add atoll(3) to libnbcompat. We need it when building target's gcc
for a 64-bit target on a 32-bit host.

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

Disable pre-compiled headers on Darwin.

Tweak dependencies so that defs.mk depends upon config.cache, and
config.cache depends upon 'include/.stamp configure config.h.in defs.mk.in'
and runs configure. Forcebly remove config.cache before running configure.

This change means that config.cache is (still) retained between "make clean"
(but not "make cleandir") runs, but is flushed if configure or config.h.in
is changed, as the cache may contain incorrect information in that case.

* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
in libnbcompat. The host tools use features of the NetBSD versions
which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.

to make the toolchain cross-build on Mac OS X. Nozaki-san has addressed
the other issues.

branches: 1.67.2;
The tools/compat versions of mkstemp() and mkdtemp() need to call the
internal function that's usually named "__gettemp". However in a cross
build, "__gettemp" is in a namespace reserved for the host system, so we
can't use that. Use "__nbcompat_gettemp" instead, following the example
of several other functions or macros in tools/compat. Previously, this
was handled by using the name "gettemp", but that conflicts with the
local gettemp() function in dist/nawk.

Define __USE_ISOC99 for linux, making the isblank() proto appear.
This is probably not the Right Thing, but it seems to not break anything.

Try to address mess with user_from_uid and friends by ensuring we always
get our versions if any of the functions aren't present on the host system.

Still assumes if the functions are all there, they work like ours, which
may be a problem too.

I am now convinced of the error of my ways, and I am checking for all the
decls mtree is using.

Move linux block up higher as it was before. noted by apb

- define the NetBSD options before including any files
- add the _NETBSD_TOOLS define to make more symbols visible
- user_from_uid and group_from_gid are renamed only if we don't have them

Add raise_default_signal().

branches: 1.60.2;
Provide definitions for {be,le}{16,32,64}{enc,dec} if necessary.
This is adapted from the very detailed fix provided by
Giles Lean in PR bin/36678.

Only one simplified implementation is provided, instead of the
two implementations conditional on __GNUC_PREREQ__(2,95) that are
provided in NetBSD's <sys/endian.h>. The use of memcpy instead of
__builtin__memcpy, and the absence of __inline or __unused, should make
it independent of GCC.

Add strndup(3) to libnbcompat, since estrndup(3) added into efun.c calls it.

Fix tools build, binstall/xinstall, for systems without id_t, e.g.
MacOS X 10.3.9. This should better match the NetBSD definition of id_t
in sys/sys/types.h.

branches: 1.57.2; 1.57.4;
kill __unused

sideways check for error functions.

Add definitions for strmode. This was missing from the
patch in PR 31232.

Use ${HOST_SH} instead of the host system's /bin/sh wherever possible:

* _PATH_BSHELL from the host's <paths.h> might be broken, so override it
with our PATH_BSHELL, which is derived from HOST_SH.

Also check for DIR.__dd_fd. tools/compat now builds on the WWDC developer
preview version of Mac OS X "Leopard".

Two changes to facilitate building tools on Darwin:

1. #undef d_fileno, which is set by Darwin's <dirent.h>,
and which clashes with d_fileno in NetBSD headers.

2. Install the sys/ufs/ header files in nbinclude/ in order
to override Darwin's own, incompatible header files.

Define prototypes for strsuftoll and strsuftollx if the one for
strsuftoll was not found by configure. Second part of nbmakefs build
on 3.0.

Adapt for bswap* changes in configure.ac.

change #include <sys/endian.h> => #include <machine/endian.h> so that
it's (more) consistent in the tree; this, along with changing tools/compat's
autoconf detection from AC_CHECK_FUNCS to AC_CHECK_DECLS makes the vast
majority of htobe16 and friends' redefinition errors bite the dust.
Tested with -current and FreeBSD.

Make cross compiling NetBSD under Linux work again. Problem noted by
R. Huvendiek on "current-users" mailing list.

UINT8_MAX and UINT16_MAX are needed for disklabel.

Define "_PATH_VI" if necessary to make cross-building work again under
Solaris (and potentially other platforms) after "disklabel" has been
added to the hosts tools.

Provide a definition for __UNCONST since there's no guarentee our sys/cdefs.h
gets pulled in

Add heapsort to libnbcompat

Define "_ISOC99_SOURCE" when building under NetBSD to get the prototypes
for strtoll() and strtoull(). This fixes PR toolchain/26021.

Redo the last commit. _NETBSD_SOURCE should never be used/referenced anymore.
So, don't wrap definitions in it, and instead check for it and #error out
if it somehow leaks into scope.

Tested a complete build to sets on x86 from a clean source tree.

- Wrap around #if !_NETBSD_SOURCE the definitions of u_{long,int,short,char}
- Protect dirfd() macro so that we don't re-define it.

These changes make my build proceed further.

The problem is that automatically generated files, might include system
files before they include anything else (for example our yacc skeleton
includes <stdlib.h> before it does anything else). This foils the scheme
of defining _POSIX_SOURCE and friends so that _NETBSD_SOURCE does not
get defined; in fact, we include many files with _NETBSD_SOURCE defined,
enough to cause confusion in compat_defs.h which tries to re-define things.

On NetBSD boxes make sure and provide prototypes for strtouq since quad_t gets
exposed all the time, but routines which use it do not. Otherwise callers
of strtouq will lose.
XXX: Need to come back through here and clean up the configure tests better
for this

Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Oops, missed a spot where we need to handle group_from_gid() separately.

Handle group_from_gid() on its own.

Before sucking in stdlib.h check if this is NetBSD. If so, explicitly make
sure to use _POSIX_C_SOURCE and undef _NETBSD_SOURCE so the myriad of NetBSD
extentions don't get pulled into scope (and likely conflict at some point
with branched code trying to build on -current due to drift). Fixes PR#25533

XXX: The entire process here is just wacky and the entire cross tools process
needed to be reviewed to build clean w. just _POSIX_C_SOURCE or the equiv
set on NetBSD hosts or this will lose again somewhere..

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:

As discussed briefly on tech-toolchain, AIX doesn't have "u_long",

Add atoll(3) to libnbcompat. We need it when building target's gcc
for a 64-bit target on a 32-bit host.

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

Check for sys/socket.h and socklen_t.

* Check for mkstemp() and mkdtemp(), and build them into libnbcompat

* mktemp is now a host-tool, so nuke the lame script (which isn't even
properly installed during the tools bootstrap).

Add __restrict to the set of tokens we #define away: our glob.h uses it.

Fine-grain checking somewhat:
* check for user_from_uid() in addition to pwcache_userdb()

Always use NetBSD's fts(3) in compat builds. Some systems (notably

* Always include the NetBSD glob(3) in libnbcompat, as the host
tools use some features of glob(3) that are not available on
all systems.
* Always include the NetBSD vis(3) in libnbcompat, since vis(3)
is not really standardized, and the vis(3) present on some systems
is different from ours.
* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
in libnbcompat. The host tools use features of the NetBSD versions
which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.
* Add a check for termios.h -- the Heimdal host tools want it.

Rather than hardcoding two possible locations of the POSIX shell (for
Solaris and everything else), set _PATH_BSHELL to the first occurrence of

Create sys/endian.h if it doesn't exist, since rmd160.c includes it directly.

Emit an empty <stdint.h> if the host doesn't have one. Should fix PR 16416.

Re-add test for <sys/endian.h>; it disappeared somewhere along the way.

Add a stub issetugid() for platforms that don't have it. For now, we assume
that no host program will be installed set-id, so the stub function always

Revert addition of mkdtemp() to libnbcompat. I don't think we need mktemp(1)

Add mkdtemp to libnbcompat, since glibc doesn't have it an mktemp(1) will

Add the md[245], sha1 and rmd160 functions to libnbcompat, conditional on their

This will be necessary to make cksum into a host tool.

Don't gratuitously touch the replacement headers in ${.OBJDIR}/include;
instead, touch them only if they're changed.

Move inttypes.h to list of auto-generated-empty headers.

Add compat defns for uint*_t (the non-underscored ones).
[The logic in all of this is ugly, and should instead be fixed up to use
AC_CHECK_SIZEOF to use primitives if the counterpart type is unavailable.]

Add some more bits of host compatibility.

Roll in fixes to permit cross-compiling from non-NetBSD hosts. This
round has been tested on Solaris/x86 and Linux hosts.

* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep

* Add more compat #defines and autoconf-checked functions.

Make almost all tools compile and run properly on non-NetBSD hosts. (In
particular, most tools now run correctly on Solaris 7.)

- Replace pwcache(3) if necessary (pwcache_userdb(3) is checked for).

tools/compat: provide nb_check_cc_flag.m4

Implement m4 macro NB_CHECK_CC_FLAG(FLAG, [VAR=FLAG_DERIVED])
Determine if the C compiler supports FLAG,
and sets output variable VAR to FLAG if FLAG is supported.

If VAR is not provided, default to FLAG_DERIVED, which is
FLAG converted to upper-case and all special characters
replaced with "_", and the result prepended with "CC_".
FLAG_DERIVED is appended to the m4 macro NB_CHECK_CC_FLAG_VARS.
E.g., if FLAG is "-Wexample=yes", FLAG_DERIVED is "CC_WEXAMPLE_YES".

This is implemented in separate buildaux/nb_check_cc_flag.m4,
based on configure's NB_CC_FLAG(), but supports VAR override.

Adapt configure from internal NB_CC_FLAG() to NB_CHECK_CC_FLAG().

(Note: AX_CHECK_COMPILE_FLAG() from autoconf-archive could be enhanced
to support the clang and gcc workarounds I've implemented here.)

tools/compat: support all bsd.own.mk disabled warnings

CC_WNO_ADDRESS_OF_PACKED_MEMBER which is set from both
@CC_WNO_ADDRESS_OF_PACKED_MEMBER@ (gcc) and
@CC_WNO_ERROR_ADDRESS_OF_PACKED_MEMBER@ (clang).

tools/compat: disable host CC warnings

Determine if the host CC supports flags to disable various
warnings similar to <bsd.own.mk> GCC_*, CLANG_*, and CC_*,
and override the <bsd.own.mk> equivalents in defs.mk.

Silences "warning: unknown warning option '...'" from our source.
External source (e.g., binutils and gcc) need their own fixes
to enhance their detection of supported clang compiler flags.

tools/compat: detect supported host compiler flags

Define NB_CC_FLAG(FLAG) to use AX_CHECK_COMPILE_FLAG
to determine if the host compiler supports FLAG
and define and AC_SUBST CC_FLAG if so.

Use workarounds to force clang to hard-fail on unknown -Wwarning,
and gcc to use -WWARN to check unknown -Wno-WARN because the
latter doesn't cause an error in gcc.

In the future we could use NB_CC_FLAG([-fcommon]) for
older NetBSD release branches compiled with host gcc 10+.

Rework Darwin -no-cpp-precomp check to use NB_CC_FLAG().
Note: this flag probably hasn't been required on macOS (Darwin)
for a long time, but serves as a good example on how to use this.

Display varaibles at the end of configure to show what was detected.

Non of the tools Makefiles needs HAVE_PTHREAD_H, so don't
AC_SUBST it or provide in defs.mk.

ctfmerge: fix macOS semaphore implementation

Use dispatch_semaphore_create() if present instead of sem_init().

macOS doesn't actually implement sem_init() (et al)
(even though it provides the prototypes as deprecated).
This was detected by the previous commit to ctfmerge
that added error handling.

Implement ctfmerge's barrier operations in terms of
dispatch(3) APIs such as dispatch_semaphore_create() (et al).

More properly host-tool-ify stat

As discussed briefly on tech-toolchain, AIX doesn't have "u_long",
so add a check for that. Partial fix for PR toolchain/22177.

Add atoll(3) to libnbcompat. We need it when building target's gcc
for a 64-bit target on a 32-bit host.

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

Move -no-cpp-precomp logic to defs.mk.

Add a HOST_BSHELL make var which contains the path to the working
shell.

branches: 1.4.2;
Roll in fixes to permit cross-compiling from non-NetBSD hosts. This
round has been tested on Solaris/x86 and Linux hosts.

* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.

Make almost all tools compile and run properly on non-NetBSD hosts. (In
particular, most tools now run correctly on Solaris 7.)

Make many host tools compile on non-NetBSD hosts. Not complete, but
very nearly there.

Add the framework for autoconf-based src/tools/compat structure. This will
(after it is more fleshed out) allow the host tools to work more cleanly
on non-NetBSD hosts.

branches: 1.2.4; 1.2.10;
don't leak on error.

use c comments

don't lie in the comment; this is not the re-entrant version

Switch to a version that does not suffer from reporting the wrong length
if the file contains NULs. From OpenBSD.

PR/34848: Roland Illig: NetBSD's sed cannot handle files that are missing
the final new line.
This is an fgetln() problem; fix and add a way to test.

Remove advertising clause.

Replace the original fgetln with a simpler one that:
1. Works if the last line does not end up in \n
2. Does not scan the string multiple times.
3. Does not copy the string, but writes it directly in the buffer.
4. Handles out of memory conditions gracefully.

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

netbsd.org->NetBSD.org

Include config.h unconditionally; clean up.

White space nit.

Use the first argument of getmode() to modify the second arg, instead of
just replacing the second arg. This lets the higher order file type bits
survive. Fixes problems with the tools version of mknod(8).
