Create a private library directory (LIBPRIVATEDIR) for libraries which
we don't want to expose but which can't or shouldn't be static.

To mark a library as private, define PRIVATELIB in its Makefile. It
will be installed in LIBPRIVATEDIR, which is normally /usr/lib/private
(or /usr/lib32/private for 32-bit libraries on 64-bit platforms).

To indicate that a program or library depends on a private library,
define USEPRIVATELIB in its Makefile. The correct version of
LIBPRIVATEDIR will be added to its run-time library search path.

Fix install from read-only obj dir when SHLIB_LDSCRIPT is used.

Add a new knob WITH_DEBUG_FILES to control the building of standalone
debug files for userland programs and libraries. The "-g" debug flag
is automatically applied when WITH_DEBUG_FILES is set.

The debug files are now named ${prog}.debug and ${shlib}.debug for
consistency with other systems and documentation. In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
debug files.

Thanks to everyone who contributed changes, review, and testing during
development.

The build system is really intricate and I had a hard time to remind the

Add support for the Compact C Type (CTF) conversions throughout FreeBSD's
system makefiles.

Note that the CTF conversion defaults to off. We may choose to change this
default later if DTrace proves popular and people are prepared to wear
the compilation performance impact of compiling with debug symbols all the
time.

Setting NO_CTF in the make args or user environment turns off CTF conversion.
Even if we choose to default CTF generation to on later, we still need
NO_CTF so that the buildworld process can bootstrap the tools without
needlessly generating CTF data for temporary tools.

Setting WITH_CTF in the make args or user environment (and _NOT_ in
/etc/make.conf) is the only way to enable CTF data conversion. Nore that
this can't be implemented the same way that the WITH_ and WITHOUT_ stuff
is implemented throughout the buildworld because the CTF conversion needs
to work when building a simple object without a Makefile, using the
default rules in sys.mk.

Typing 'make test.o' with no makefile and just a source file test.c
should work. Also, typing 'make WITH_CTF=1 test.o without a makefile and
just a source file test.c should work and produce an object with a CTF
elf section. Typing 'make WITH_CTF=1 CFLAGS=-g test.o' without a makefile
and just a source file test.c should produce an object with both a CTF
elf section and the debug elf sections.

In the FreeBSD build where more .mk files are used than just sys.mk
which is included my make by default, the use of DEBUG_FLAGS is the
correct way to enable a debug build. The important thing to note here
is that it is the DEBUG_FLAGS setting that prevents libraries and
programs from being stripped on installation. So, for the addition of
CTF data conversion, setting DEBUG_FLAGS to contain -g, without NO_CTF,
will cause the ctfconvert and ctfmerge build programs to be executed
also with the -g arg so that debug symbols are retained rather than
being removed after the CTF data elf section has been added.

Add DTrace libraries to the list of libnames.

Pass whatever the value of NM down to lorder. This allows one to

This are the build infrastructure changes to allow to use the

The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but
doesn't abort. They also produce CPU specific code (new instructions
of the CPU, not only CPU specific scheduling), so if you get coredumps
with signal 4 (SIGILL, illegal instruction) you've used the wrong
CPUTYPE.

Emergency backout of rev 1.152. This is a 100% guaranteed way to totally
hose your system. You end up with just about everything statically linked
(except for libpam.so), which then causes all the pam users to fail.
eg: login, sshd, su etc all stop working because dlopen no longer works
because there is no libc.so in memory anymore.

gcc passes -L/usr/lib to ld. The /usr/lib/libxxx.so symlink is *not* a
compatability link. It is actually the primary link. There should be no
symlinks in /lib at all. Only /lib/libXX.so.Y.

Note no libc.so.5. Hence libpam.so.2 has unresolved dependencies.

I believe this is also the cause of the recent buildworld failures when
pam_krb5.so references -lcrypto stuff etc and when librpcsvc.so references
des_setparity() etc.

This change could not possibly have worked, unless there are other missing
changes to the gcc configuration. It won't work with ports versions of

When creating .so symlinks, use SHLIBDIR instead of LIBDIR so symlinks

The use of ld(1) to strip compiler local and non-global

thirteen years, and it now does more harm than good.

An attempt to work around the problems caused by using
ld(1) for stripping was to pass LDFLAGS to the ld(1)
command, but this was not right either as ${LDFLAGS}
should, by design, be used with cc(1) and not ld(1).

One of the proposed solutions was to use the objcopy(1)
utility to do the strip work, and the other would be to
use strip(1), but Bruce Evans suggested not stripping
any symbols at all. This works by leaving the grunt
work to the final strip(1) command (when installing the

in SUBDIRs, like we do in bsd.subdir.mk. Nothing depended on the wrong

Fixed `distribute' targets (except for the bsd.subdir.mk version) so that
they do not depend on _SUBDIR; `distribute' calls `install' which already
depends on _SUBDIR.

Obviate the need to set the COMPILER_PATH and LIBRARY_PATH in Makefile.inc1
to pick up the correct cross-tools (the compiler executables and binutils)
and special linker files (crt*.o). This is now controlled by a single knob,
TOOLS_PREFIX, when building cross-tools.

Fixed regression in Makefile.inc1,v 1.203 (-nostdinc). This clobbered target
architecture's CFLAGS with building host's CPUTYPE setting in /etc/make.conf,
and had a nice but nasty side effect of exposing some (normally hidden) bugs
in system headers.

(Attempt to move the "-nostdinc -I..." part of CFLAGS into the new CINCLUDES
(modeled after a similar CXXINCLUDES) eventually failed because hard-coding
${WORLDTMP}/usr/include to be the first in the include list does not always
work, e.g. lib/libbind.)

Compensate the -nostdinc removal by making cpp(1) built in the cross-tools
stage to not look for <> header files in the building host's /usr/include

Unbreak "make lint" for programs and "make llib-l${LIB}.ln" for
libraries a little by not passing all of ${CFLAGS} to lint. Pass
only options matching -[DIU]*. The important -nostdinc option can't
be passed like I first thought because lint misinterprets as
"-n -o stdinc". The unimportant -B* option can't be passed because
lint doesn't support it. Otherwise, we pass the same options as
to mkdep, exept for a bug in the latter: -U* is not passed. All
this depends on option args not being separated from option flags
by a space.

Fix cross-building, etc:

1. To cross-build, one now needs to set TARGET_ARCH, and not the
MACHINE_ARCH. MACHINE_ARCH should never be changed manually!

2. Initialize DESTDIR= explicitly for bootstrap-tools, build-tools,
and cross-tools stages. This fixes broken header and library
dependencies problem. We build them in the host environment,
and obviously want them to depend on host headers and libraries.
The problem with broken header dependencies for bootstrap-tools
and cross-tools was already partially solved (see BOOTSTRAPPING
tests in bsd.prog.mk and bsd.lib.mk), but it was still there for
build-tools if the user ran "make world DESTDIR=/foo". Also,
for all of these stages, the library dependencies were broken
because of how bsd.libnames.mk define DPADD members.

We still provide a glue to install bootstrap- and cross-tools
under the ${WORLDTMP}.

Removed PATH overrides for bootstrap-, build-, and cross-tools
stages. There is just no reason why we would need to override
it, and the hacks to clean up the ${WORLDTMP} in the -DNOCLEAN
case are no longer needed with fixes from this step.

That is, we now never use ${WORLDTMP} headers and libraries,
and we don't use any ${WORLDTMP} installed binaries during
these stages. Again, these stages depend solely on the host
environment, including compiler, headers, and libraries.

3. Moved "miniperl" back from cross-tools (it has nothing to do
with a cross-compiler) to build-tools where it belongs. The
change from step 1 let to do this. Also, to make this work,
build-tools targets of "cc_tools" and "miniperl" were modified
to call "depend". Here follow the detailed explanations.

There are two categories of build tools, for now. In the first
category there are "cc_tools" and "miniperl". They occupy the
whole (sub)directory, and nothing needs to be done in this
subdirectory later during the "all" stage. They are also
constructed using system makefiles. We must build the .depend
early in the build-tools stage because:

1) They use (and depend on) the host environment.

2) If we don't do this in build-tools, the "depend" stage of
buildworld will do this for us; wrong library and header
dependencies will be recorded (DESTDIR=${WORLDTMP}) and,
what's worse, the "all" stage may then clobber the
build-architecture format tools (that we built in the
build-tools stage) with the target-architecture format
ones, breaking cross build.

In the second category there are all other build-tools. They
share their directory with the "main" module that needs them
in the "all" stage, and they don't show up themselves in the
.depend file. The portion of this fix was already committed
in gnu/usr.bin/cc/cc_tools/Makefile,v 1.52.

4. "libperl" is no longer a build tool, and "miniperl" is the
stand-alone application. I had to make this change because
build-tools and "all" stages share the same object directory.
Without this change, if we cross compile, libperl.a is first
built for the build architecture during the build-tools stage
(for the purposes of immediate linkage with "miniperl").
Later on, the "all" stage sees this library as up-to-date,
and doesn't rebuild it. The effect is that the wrong format
static libperl library is installed with installworld.

5. Fixed "includes" to install secure/lib/libtelnet headers if
required.

Bring in the WARNS directive from NetBSD, localized in a new bsd.sys.mk

compiler warning flags to CFLAGS in a relatively compiler-neutral manner.

The idea is that WARNS can be set in Makefile.inc or in individual
Makefiles as they become clean, to prevent the introduction of new
warnings in the code (-Werror is added by default when WARNS > 0).

This behaviour can be overridden with the following two knobs:
NO_WARNS disables the checking of WARNS completely
NO_WERROR disables the addition of -Werror to the flags.

Additionally, setting WFORMAT to 1 (in makefiles) and/or defining
FORMAT_AUDIT (by the user) will enable increased checking of format
string arguments.

Add variable INSTALLFLAGS_EDIT used to remove arbitrary INSTALLFLAGS.

Specifically intended for removing -fschg ("INSTALLFLAGS_EDIT=:S/schg/uchg/")
this makes the NOFSCHG flag redundant. NOFSCHG will still be honoured by
bsd.lib.mk but is valid for buildworld only. NOFSCHG is still implemented in
the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }"
to emphasize the fact that NOFSCHG is only supported in a limited
fashion and for buildworld.

The interface and implementation are such that future use of flags such
as sappnd can also be easily removed or altered (perhaps to uappnd).

This commit brought to you by the letters B, D, and E, and the numbers six,
one, thirteen, and three.

Removed all traces of LN_FLAGS. It was only used to produce a link
/usr/sbin/sysctl -> ${DESTDIR}/sbin/sysctl in some versions of 2.2,
and this link was broken if DESTDIR was set.

Added a SYMLINKS macro. This works the same as LINKS, except it
creates symlinks and the linked-to pathname may be relative. This
is more flexible than LN_FLAGS, since it supports installing
symlinks independently of hard links.

Use `ln -f[s] ...' instead of `rm -f ...; ln [-s] ...' for LINKS and
SYMLINKS. This is equivalent if the target is neither a directory nor
a symlink to a directory.

Introduce a new variable NEED_LIBNAMES. If it is defined,
<bsd.libnames.mk> is included regardless of the object file format.

This is needed to fix the a.out PAM breakage that manifests itself
when trying to build login.

Add some capabilities to <bsd.lib.mk> so that it can be used for
building dlopen-able modules, and add features needed to build a
static PAM library. I think I cleaned it up some, too, but beauty
is in the eye of the beholder.

You can now build a shared library without version numbers, by
defining SHLIB_NAME to something like "pam_unix.so". If SHLIB_MAJOR
and/or SHLIB_MINOR are set, SHLIB_NAME gets the usual default value,
but it can be overridden if desired. If none of these symbols are
set, no shared library is built.

SHLIB_LINK controls the name of the symbolic link that points to
the library. If it is unset, no link is made. In the usual case,
it gets the right default: e.g., "libc.so" for ELF, nothing for
a.out. This can be overridden.

STATICOBJS can be set to a list of extra object files that should
be added to the static library but not to the shared library.
These objects are added to the profiled library too.

These changes should make it easy to use <bsd.lib.mk> for building
things such as PAM modules and dynamic linkers, for which <bsd.prog.mk>
has been abused until now.

Switch to using ".So" as the extension for PIC object files rather
than ".so". The old extension conflicted with well-established
naming conventions for dynamically loadable modules.

The "clean" targets continue to remove ".so" files too, to deal with
old systems.

Removed bitrotted code for setting OBJFORMAT.

For ELF, create a symbolic link libfoo.so -> libfoo.so.NNN in the
object tree too. This makes it possible to link against a shared
library that hasn't been installed yet.

Default to aout only on i386. Before we defaulted to elf only on
Alpha. This is a minor, but important distinction. Should be a no-op
to the install base. If OBJFORMAT is set elsewhere, things work
exactly as they did before.

Change lib specification in `clean' target to match ELF shared libs too.

Fixed generation of extra dependencies:
- the two `_EXTRADEPEND::' targets potentially clobbered each other for
`make -jN'. In practice, the output for the second target sometimes
disappeared.
- bogus dependencies were generated for static libraries.

If .depend doesn exist, then pretend that all objects depend on all
headers in ${SRCS}, as in bsd.lmod.mk and bsd.prog.mk. This helps
`make [-j]' work when .depend doesn't exist. Even plain `make'
sometimes only worked because of magic ordering in ${SRCS}.

Removed default tags target. It was identical to the central one in
bsd.dep.mk.

Choose the default binary format based on machine type.
Alpha is elf, not aout.

Oops, rm -f can't handle empty lists.

Normally don't include <bsd.libnames.mk>. Include it in the !aout case

it can be checked until it goes away.

Don't clean files that we don't create.

Fixed style of empty test.

Restore the BINFORMAT?= in sys.mk, or it's painfully difficult to use
.if in Makefiles. bsd.prog.mk and bsd.lib.mk do not depend on it however.

Allow overriding of the -soname arg when building the lib*crypt.so* libs
since libdescrypt.so and libscrupt.so both need a -soname of libcrypt.so
so that the symlink is obeyed at runtime rather than at compile time.

Change the BINFORMAT definitions so that they do not depend on sys.mk,
since 2.1.x make(1) apparently does not have the -m switch to set both
the the bsd.*.mk and sys.mk location, and this breaks 'make world' from a
2.1.x system.

A first cut at some rules for building elf shared libs. Of particular
note, using "-Wl,-f" to generate a library objects list doesn't work
anymore since the hack to ld hasn't been incorporated into binutils-2.8.
(and the -f switch is used for something else already)

This is disabled by default, don't panic! :-)

Use gcc's LIBRARY_PATH environment variable to handle DESTDIR,
instead of -L flags in LDDESTDIR. LIBRARY_PATH is documented in
the gcc info pages. It is better than using -L flags, because it
modifies the search for start-up files as well as for libraries.
A new variable LDDESTDIRENV is used to contain the normally-empty
LIBRARY_PATH environment setting.

LDDESTDIR is no longer set in <bsd.lib.mk>. It is still honored for
the time being, because a couple of userland Makefiles still (wrongly)
set it. These should be fixed, and LDDESTDIR should vanish.

Removed the commented-out "LDDESTDIR+=-nostdlib", because "gcc -shared"

Removed the ".if defined(LDADD)" around the _EXTRADEPEND target for

Use "-pg" instead of "-p" for generating profiled object files.
The two options differ only when linking, but "-p" is incorrect

Use `ld -f' (actually `cc -Wl,-f') at `make depend' time to generate
almost perfect dependencies on crt0's and libraries. DPADD and
bsd.libnames.mk should go away soon. Use a new _EXTRADEPEND target
to implement this and to avoid editing of .depend when .depend isn;t
being rebuilt. The afterdepend target doesn't seem to be good for
anything and is now unused.

Fixed LDDESTDIR for the DESTDIR case when ${SHLIBDIR} != /usr/lib.

Added commented-out -nostdlib to LDDESTDIR for the DESTDIR case.
The wrong libraries may be used without this; however it breaks

.TARGETOBJDIR has been removed from make and CANONICALOBJDIR set in

RANTOUCH may be defined in /etc/make.conf as

Emendation to previous commit: only create static INTERNALLIBs if
INTERNALSTATICLIB is also set.

It turns out that occasionally you want both shared and static versions
of INTERNALLIBs, so generate both.

Add support for DEBUG_FLAGS. If you say something like:

make DEBUG_FLAGS=-g2

You can compile something for debugging at debugging level 2.
It will also take care not to strip the resulting executable(s).

Use ${ECHO} instead of `echo' so that `make -s' is fairly quiet.

Add support for two modifier variables which will be useful soon:

PRECIOUSLIB causes the shared library to be installed with the system
immutable flag (schg) set. (You can add other flags for shared-library
installation by modifying SHLINSTALLFLAGS.)

INTERNALLIB disables the generation of non-shared versions of the library.
This may be of use for programs like Taylor UUCP and GCC which have large
internal libraries shared among a number of programs.

Make the install targets obey the INSTALLFLAGS requests in the new
Makefiles.

DANGER WILL ROBINSON!

This will cause repeat installs of certain programs, such as `init' and
`rcp', to fail unless one of the two conditions is met:

1) You are in single-user mode.
2) Your security level is set to 0 or -1.

If you have compiled a kernel from the latest sources, your kernel
security level is set to -1 by default, which will keep `init' from
fiddling with it. You can increase it, but not decrease it, from the
command line with the command `sysctl -w kern.securelevel=<new value>'.
I believe that -1 is the most appropriate value to use while we are still
developing the code, although when we ship it should be changed back to 0.

See init(8) for more information.

Don't pass ${LDADD} to ${AR}. Use ${ARADD} for that.
