Miscellaneous

Added advantage is that this will work out-of-the-box on pkgsrc and FreeBSD's ports, since these define PREFIX to be their installation paths.

Make include files (types of projects)

bsd.prog.mk (programs)

Expects a manpage of the name ${PROG}.1, if MAN is not defined. Initialise MAN to an empty value if you do not have a manpage:

PROG=foo
SRCS=foo.c
MAN=
.include <bsd.prog.mk>

bsd.lib.mk (libraries)

Does not create shared libraries unless you define SHLIB_MAJOR variable:

LIB=this
SHLIB_MAJOR=1
SHLIB_MINOR=0
.include <bsd.lib.mk>

You may define SHLIB_TINY variable too.

Alternatively, you may define variables in "shlib_version" file:

major=0
minor=1

where the 0 and 1 are replaced by the appropriate version numbers, of course.

bsd.man.mk (manpage stuff)

You can automatically have BSD Make create symlinks to your base manpages by defining MLINKS as a list of manpage.1 linkname.1 tuples separated by spaces. Example:

MLINKS = real_foo.3 foo.3  real_foo.3 other_foo.3

Here, real_foo.3 is a real file, the rest are all links that will be created in the installation path.

Special constructs

Special constructs (.if, .for, .include etc) must have their dot flush left aligned. The word after the dot may be indented, however. You can check the current target being built by make with

.if make(targname)
blah
.endif

where targname is the target you're checking for.

When you check the contents of a variable, if it does not exist (it hasn't been defined), you will get 'strange' errors:

.if ${VAR} == "yes"
blah
.endif

will get you:

make: "/home/foo/src/libfoo" line 7: Malformed conditional (${VAR} == "yes")
make: "/home/foo/src/libfoo" line 7: Need an operator
make: "/home/foo/src/libfoo" line 9: if-less endif
make: "/home/foo/src/libfoo" line 9: Need an operator
make: Fatal errors encountered -- cannot continue

This kind of error is quite subtle since it might never occur on your system because you happen to always have the variable defined. To fix this, enclose the tested variable in quotes:

.if "${VAR}" == "yes"
blah
.endif

(The first example evaluates to .if == "yes" while the second to something slightly different: .if "" == "yes")
