1.1       cgd         3:
1.213     lukem       4: This is the README file for the make "include" files for the NetBSD
                      5: source tree.  The files are installed in /usr/share/mk, and are,
                      6: by convention, named with the suffix ".mk".
1.1       cgd         7:
                      8: Note, this file is not intended to replace reading through the .mk
                      9: files for anything tricky.

                     12:
                     13: RANDOM THINGS WORTH KNOWING:
                     14:
                     15: The files are simply C-style #include files, and pretty much behave like
                     16: you'd expect.  The syntax is slightly different in that a single '.' is
                     17: used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
                     18:
                     19: One difference that will save you lots of debugging time is that inclusion
                     20: of the file is normally done at the *end* of the Makefile.  The reason for
                     21: this is because .mk files often modify variables and behavior based on the
                     22: values of variables set in the Makefile.  To make this work, remember that
                     23: the FIRST target found is the target that is used, i.e. if the Makefile has:
                     24:
                     25:        a:
                     26:                echo a
                     27:        a:
                     28:                echo a number two
                     29:
                     30: the command "make a" will echo "a".  To make things confusing, the SECOND
                     31: variable assignment is the overriding one, i.e. if the Makefile has:
                     32:
                     33:        a=      foo
                     34:        a=      bar
                     35:
                     36:        b:
                     37:                echo ${a}
                     38:
                     39: the command "make b" will echo "bar".  This is for compatibility with the
                     40: way the V7 make behaved.
                     41:
                     42: It's fairly difficult to make the BSD .mk files work when you're building
1.75      agc        43: multiple programs in a single directory.  It's a lot easier to split up the
1.1       cgd        44: programs than to deal with the problem.  Most of the agony comes from making
1.36      ross       45: the "obj" directory stuff work right, not because we switched to a new version
1.1       cgd        46: of make.  So, don't get mad at us, figure out a better way to handle multiple
                     47: architectures so we can quit using the symbolic link stuff.  (Imake doesn't
                     48: count.)
                     49:
                     50: The file .depend in the source directory is expected to contain dependencies
                     51: for the source files.  This file is read automatically by make after reading
                     52: the Makefile.
                     53:
                     54: The variable DESTDIR works as before.  It's not set anywhere but will change
                     55: the tree where the file gets installed.
                     56:
                     57: The profiled libraries are no longer built in a different directory than
                     58: the regular libraries.  A new suffix, ".po", is used to denote a profiled
1.265     njoly      59: object, and ".pico" denotes a shared (position-independent) object.
1.97      itojun     60:
1.142     lukem      61: There are various make variables used during the build.
                     62:
                     63: Many variables support a (case sensitive) value of "no" or "yes",
                     64: and are tested with  ${VAR} == "no"  and  ${VAR} != "no" .
                     65:
                     66:
1.172     hubertf    67: The basic rule for the variable naming scheme is as follows:
                     68:
1.231     apb        69: HOST_xxx       A command that runs on the host machine regardless of
                     70:                whether or not the system is being cross compiled, or
                     71:                flags for such a command.
                     72:
1.172     hubertf    73: MKxxx          Can be set to "no" to disable functionality, or
                     74:                "yes" to enable it.
                     75:                Usually defaults to "yes", although some variables
                     76:                default to "no".
                     77:                Due to make(1) implementation issues, if a temporary
1.224     lukem      78:                command-line override of a mk.conf(5) or <bsd.own.mk>
1.214     wiz        79:                setting is required whilst still honoring a particular
1.172     hubertf    80:                Makefile's setting of MKxxx, use
                     81:                        env MKxxx=value make
                     82:                instead of
                     83:                        make MKxxx=value
                     84:
                     85: NOxxx          If defined, disables a feature.
                     86:                Not intended for users.
                     87:                This is to allow Makefiles to disable functionality
                     88:                that they don't support (such as missing man pages).
                     89:                NOxxx variables must be defined before <bsd.own.mk>
                     90:                is included.
                     91:
1.231     apb        92: TOOL_xxx       A tool that is provided as part of the USETOOLS
                     93:                framework.  When not using the USETOOLS framework,
                     94:                TOOL_xxx variables should refer to tools that are
                     95:                already installed on the host system.
                     96:
1.172     hubertf    97: The following variables that control how things are made/installed that
                     98: are not set by default. These should not be set by Makefiles; they're for
1.224     lukem      99: the user to define in MAKECONF (see <bsd.own.mk>, below, or mk.conf(5))
                    100: or on the make(1) command line:
1.172     hubertf   101:
                    102: BUILD          If defined, 'make install' checks that the targets in the
                    103:                source directories are up-to-date and remakes them if they
                    104:                 are out of date, instead of blindly trying to install
                    105:                 out of date or non-existent targets.
                    106:
