XXX This document is seriously out of date, it is currenly being revised.

|
|
This is the README file for the new make "include" files for the BSD
|
|
source tree. The files are installed in /usr/share/mk, and are, by
|
|
convention, named with the suffix ".mk". Each ".mk" file has a
|
|
corresponding ".rd" file which is an explanation of the ".mk" file.
|
|
|
|
Note, this file is not intended to replace reading through the .mk
|
|
files for anything tricky.

|
|
RANDOM THINGS WORTH KNOWING:
|
|
|
|
The files are simply C-style #include files, and pretty much behave like
|
|
you'd expect. The syntax is slightly different in that a single '.' is
|
|
used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
|
|
|
|
One difference that will save you lots of debugging time is that inclusion
|
|
of the file is normally done at the *end* of the Makefile. The reason for
|
|
this is because .mk files often modify variables and behavior based on the
|
|
values of variables set in the Makefile. To make this work, remember that
|
|
the FIRST target found is the target that is used, i.e. if the Makefile has:
|
|
|
|
a:
|
|
echo a
|
|
a:
|
|
echo a number two
|
|
|
|
the command "make a" will echo "a". To make things confusing, the SECOND
|
|
variable assignment is the overriding one, i.e. if the Makefile has:
|
|
|
|
a= foo
|
|
a= bar
|
|
|
|
b:
|
|
echo ${a}
|
|
|
|
the command "make b" will echo "bar". This is for compatibility with the
|
|
way the V7 make behaved.
|
|
|
|
It's fairly difficult to make the BSD .mk files work when you're building
|
|
multiple programs in a single directory. It's a lot easier split up the
|
|
programs than to deal with the problem. Most of the agony comes from making
|
|
the "obj" directory stuff work right, not because we switch to a new version
|
|
of make. So, don't get mad at us, figure out a better way to handle multiple
|
|
architectures so we can quit using the symbolic link stuff. (Imake doesn't
|
|
count.)
|
|
|
|
The file .depend in the source directory is expected to contain dependencies
|
|
for the source files. This file is read automatically by make after reading
|
|
the Makefile.
|
|
|
|
The variable DESTDIR works as before. It's not set anywhere but will change
|
|
the tree where the file gets installed.
|
|
|
|
The profiled libraries are no longer built in a different directory than
|
|
the regular libraries. A new suffix, ".po", is used to denote a profiled
|
|
object.
|
|
|
|

|
|
|
|
The include file <sys.mk> has the default rules for all makes, in the BSD
|
|
environment or otherwise. You probably don't want to touch this file.
|
|
|
|
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
|
|
|
|
The include file <bsd.man.mk> handles installing manual pages and their
|
|
links.
|
|
|
|
It has a single target:
|
|
|
|
maninstall:
|
|
Install the manual pages and their links.
|
|
|
|
It sets/uses the following variables:
|
|
|
|
MANDIR Base path for manual installation.
|
|
|
|
MANGRP Manual group.
|
|
|
|
MANOWN Manual owner.
|
|
|
|
MANMODE Manual mode.
|
|
|
|
MANSUBDIR Subdirectory under the manual page section, i.e. "/vax"
|
|
or "/tahoe" for machine specific manual pages.
|
|
|
|
MAN1 ... MAN8 The manual pages to be installed (use a .0 suffix).
|
|
|
|
MLINKS List of manual page links (using a .1 - .8 suffix). The
|
|
linked-to file must come first, the linked file second,
|
|
and there may be multiple pairs. The files are soft-linked.
|
|
|
|
The include file <bsd.man.mk> includes the include file <bsd.inc.mk>.
|
|
|
|
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
|
|
|
|
The include file <bsd.own.mk> contains the owners, groups, etc. for both
|
|
manual pages and binaries.
|
|
|
|
It has no targets.
|
|
|
|
It sets/uses the following variables:
|
|
|
|
BINGRP Binary group.
|
|
|
|
BINOWN Binary owner.
|
|
|
|
BINMODE Binary mode.
|
|
|
|
STRIP The flag passed to the install program to cause the binary
|
|
to be stripped. This is to be used when building your
|
|
own install script so that the entire system can be made
|
|
stripped/not-stripped using a single nob.
|
|
|
|
MANDIR Base path for manual installation.
|
|
|
|
MANGRP Manual group.
|
|
|
|
MANOWN Manual owner.
|
|
|
|
MANMODE Manual mode.
|
|
|
|
This file is generally useful when building your own Makefiles so that
|
|
they use the same default owners etc. as the rest of the tree.

|
|
|
The include file <bsd.prog.mk> handles building programs from one or
|
|
more source files, along with their manual pages. It has a limited number
|
|
of suffixes, consistent with the current needs of the BSD tree.
|
|
|
|
It has seven targets:
|
|
|
|
all:
|
|
build the program and its manual page
|
|
clean:
|
|
remove the program, any object files and the files a.out,
|
|
Errs, errs, mklog, and ${PROG}.core.
|
|
cleandir:
|
|
remove all of the files removed by the target clean, as
|
|
well as .depend, tags, and any manual pages.
|
|
depend:
|
|
make the dependencies for the source files, and store
|
|
them in the file .depend.
|
|
install:
|
|
install the program and its manual pages; if the Makefile
|
|
does not itself define the target install, the targets
|
|
beforeinstall and afterinstall may also be used to cause
|
|
actions immediately before and after the install target
|
|
is executed.
|
|
lint:
|
|
run lint on the source files
|
|
tags:
|
|
create a tags file for the source files.
|
|
|
|
It sets/uses the following variables:
|
|
|
|
BINGRP Binary group.
|
|
|
|
BINOWN Binary owner.
|
|
|
|
BINMODE Binary mode.
|
|
|
|
CLEANFILES Additional files to remove for the clean and cleandir targets.
|
|
|
|
COPTS Additional flags to the compiler when creating C objects.
|
|
|
|
HIDEGAME If HIDEGAME is defined, the binary is installed in
|
|
/usr/games/hide, and a symbolic link is created to
|
|
/usr/games/dm.
|
|
|
|
LDADD Additional loader objects. Usually used for libraries.
|
|
For example, to load with the compatibility and utility
|
|
libraries, use:
|
|
|
|
LDFILES=-lutil -lcompat
|
|
|
|
LDFLAGS Additional loader flags.
|
|
|
|
LINKS The list of binary links; should be full pathnames, the
|
|
linked-to file coming first, followed by the linked
|
|
file. The files are hard-linked. For example, to link
|
|
/bin/test and /bin/[, use:
|
|
|
|
LINKS= ${DESTDIR}/bin/test ${DESTDIR}/bin/[
|
|
|
|
MAN1...MAN8 Manual pages (should end in .0). If no MAN variable is
|
|
defined, "MAN1=${PROG}.0" is assumed.
|
|
|
|
PROG The name of the program to build. If not supplied, nothing
|
|
is built.
|
|
|
|
SRCS List of source files to build the program. If PROG is not
|
|
defined, it's assumed to be ${PROG}.c.
|
|
|
|
DPADD Additional dependencies for the program. Usually used for
|
|
libraries. For example, to depend on the compatibility and
|
|
utility libraries use:
|
|
|
|
SRCLIB=${LIBCOMPAT} ${LIBUTIL}
|
|
|
|
The following libraries are predefined for DPADD:
|
|
|
|
LIBCRT0 /usr/lib/crt0.o (sic)
|
|
LIBC /usr/lib/libc.a
|
|
LIBCOMPAT /usr/lib/libcompat.a

STRIP The flag passed to the install program to cause the binary
|
|
to be stripped.
|
|
|
|
SUBDIR A list of subdirectories that should be built as well.
|
|
Each of the targets will execute the same target in the
|
|
subdirectories.
|
|
|
|
The include file <bsd.prog.mk> includes the include files <bsd.inc.mk>
|
|
and <bsd.man.mk>.
|
|
|
|
Some simple examples:
|
|
|
|
To build foo from foo.c with a manual page foo.1, use:
|
|
|
|
PROG= foo
|
|
|
|
.include <bsd.prog.mk>
|
|
|
|
To build foo from foo.c with a manual page foo.2, add the line:
|
|
|
|
MAN2= foo.0
|
|
|
|
If foo does not have a manual page at all, add the line:
|
|
|
|
NOMAN= noman
|
|
|
|
If foo has multiple source files, add the line:
|
|
|
|
SRCS= a.c b.c c.c d.c
|
|
|
|

|
|
|
|
The include file <bsd.subdir.mk> contains the default targets for building
|
|
subdirectories. It has the same seven targets as <bsd.prog.mk>: all, clean,
|
|
cleandir, depend, install, lint, and tags. For all of the directories
|
|
listed in the variable SUBDIRS, the specified directory will be visited
|
|
and the target made. There is also a default target which allows the
|
|
command "make subdir" where subdir is any directory listed in the variable
|
|
SUBDIRS.
|
|
|

|
|
|
|
The include file <bsd.lib.mk> has support for building libraries. It has
|
|
the same seven targets as <bsd.prog.mk>: all, clean, cleandir, depend,
|
|
install, lint, and tags. It has a limited number of suffixes, consistent
|
|
with the current needs of the BSD tree.
|
|
|
|
It sets/uses the following variables:
|
|
|
|
LIBDIR Target directory for libraries.
|
|
|
|
LINTLIBDIR Target directory for lint libraries.
|
|
|
|
LIBGRP Library group.
|
|
|
|
LIBOWN Library owner.
|
|
|
|
LIBMODE Library mode.
|
|
|
|
LDADD Additional loader objects.
|
|
|
|
MAN1 ... MAN8 The manual pages to be installed (use a .0 suffix).
|
|
|
|
SRCS List of source files to build the library. Suffix types
|
|
.s, .c, and .f are supported. Note, .s files are preferred
|
|
to .c files of the same name. (This is not the default for
|
|
versions of make.)
|
|
|
|
The include file <bsd.lib.mk> includes the include files <bsd.inc.mk>
|
|
and <bsd.man.mk>.
|
|
|
|
It has rules for building profiled objects; profiled libraries are
|
|
built by default.
|
|
|
|
Libraries are ranlib'd before installation.
