Make Variables

The following make variables are used by imake rules and may be set in
an individual Imakefile.

DEFINES			program-specific -D flags and other arguments
			to pass to the C compiler, lint, and makedepend.
DEPEND_DEFINES		program-specific flags in addition to
			$(DEFINES) to pass to lint and makedepend.
			This is usually used when there are special
			compilation rules for individual files, and
			the defines passed to those files affect
			makedepend results.  If they can be passed to
			all files during the makedepend step without
			affecting the results for other files,
			DEPEND_DEFINES is used to do that.  Example is
			the Xlib Imakefile.
INCLUDES		program-specific -I flags.
HEADERS			.h files to install with "make includes" and
			"make install".  If this Imakefile includes
			Library.tmpl there are no headers, include
			this line instead of a HEADERS definition:
			#define LibHeaders NO
REQUIREDLIBS		when building a shared library, other libraries used
			by this library that should be referenced at
			link time.
LINTLIBS		program-specific libraries for lint.
LOCAL_LDFLAGS		program-specific flags for the linker.
LOCAL_LIBRARIES		project libraries (usually specified
			as -lname) needed by this program.
			For example, "-lXt -lXext -lX11".
			Used by SimpleProgramTarget and
			ComplexProgramTarget* rules.
			Do not include any system-specific libraries here.
SYS_LIBRARIES		system libraries (usually specified
			as -lname) needed by this program.
			For example "MathLibrary".
			Do not include any system-specific libraries
			such as "-lnsl" here; they are automatically
			added to the link command by the
			vendor-specific .cf file.
SUBDIRS			for an Imakefile in a directory containing
			subdirectories, this names the subdirectories.
			Such an Imakefile also needs to #define IHaveSubdirs
			and call MakeSubdirs() and DependSubdirs().
MANSUFFIX		suffix used by InstallManPage* rules.
			May be set to $(LIBMANSUFFIX), $(FILEMANSUFFIX), or
			$(MISCMANSUFFIX) in directories for libraries or data 
			files.


Rule-specific variables that may be set in an individual Imakefile.
If you aren't using these rules, you may need variables with a similar
function, but you need not use these names.  However, following these
conventions may make your Imakefile easier to read and maintain.

DEPLIBS			library dependencies for ComplexProgramTarget
SRCS			source files used by ComplexProgramTarget and
			DependTarget.
OBJS			object files used by ComplexProgramTarget
PROGRAMS		default target used with ComplexProgramTarget_(n)
SRCS1			source files used by ComplexProgramTarget_1
OBJS1			object files used by ComplexProgramTarget_1
DEPLIBS1		library dependencies for ComplexProgramTarget_1
SRCS2			source files used by ComplexProgramTarget_2
OBJS2			object files used by ComplexProgramTarget_2
DEPLIBS2		library dependencies for ComplexProgramTarget_2
SRCS3			source files used by ComplexProgramTarget_3
OBJS3			object files used by ComplexProgramTarget_3
DEPLIBS3		library dependencies for ComplexProgramTarget_3

Variables that can be set on the make command line:

DESTDIR			directory under which "make install" should
			install instead of "/"; used only for testing
			"make install" rules, binary package building,
			and specifying alternative installation directories
			for cross compiles.
FILE			file for "lint1" target to run lint on.
CDEBUGFLAGS		-g and/or -O flag to control C compiler optimization.
CXXDEBUGFLAGS		-g and/or -O flag to control C++ optimization.
LDSTRIPFLAGS		flag to have linker strip objects (typically -x).
			Typically set to the empty string to prevent
			the linker from stripping objects; use this
			way when setting CDEBUGFLAGS to "-g".

These variables are set in project-specific files such as X11.tmpl.
They should NOT be set in an Imakefile.  These variables are sometimes
misused; they are included here to remind Imakefile writers NOT to use
them:

EXTRA_DEFINES		project-specific -D flags
EXTRA_INCLUDES		project-specific -I flags
EXTRA_ICONFIGFILES	Additional project-specific imake config files
			to add to ICONFIGFILES.
			This is a list of files that define variables
			that might affect compilation of some files.

Many other make variables are set up by the imake config files and can
be used in an Imakefile.  The easiest way to discover them is to look
at the Makefile generated by an empty Imakefile.


Comments

Use C comment syntax in an Imakefile for comments that should not
appear in the resulting Makefile.
Use "XCOMM" at the start of each
line to produce a comment that will appear in the Makefile.
(The "XCOMM" will
be translated into the Makefile comment character "#" by imake.)
Do NOT use "#" as a comment character in Imakefiles; it confuses the C
preprocessor used by imake on some systems.


Imake variables

Don't abuse the variables in X11.tmpl that describe
particular pieces of X by using them to describe your own subsystems.
Instead, create new variables that are defaulted using
Imake.tmpl variables.


Examples

Since the easiest way to write an Imakefile is to start with one that
works, here are some short, easy-to-read Imakefile examples in the X
distribution:

with subdirs:	config/Imakefile
library:	lib/Xau/Imakefile
simple program: programs/xdpyinfo/Imakefile
complex progs:  programs/xclipboard/Imakefile
complex prog:	programs/xmodmap/Imakefile

Common Rules

Here are some of the common rules for building programs.  How to use
them is described in Imake.rules and in the O'Reilly book "Software
Portability with imake."

Basic program-building rules

All of these except NormalProgramTarget also generate rules to install
the program and its manual page, and to generate dependencies.

SimpleProgramTarget	Use if there is only one program to be made
			and it has only one source file.

ComplexProgramTarget	Use if there is only one program to be made
			and it has multiple source files.  Set SRCS to
			the names of the source files, set OBJS to
			the names of the object files, and set DEPLIBS
			to the libraries that this program depends on.

ComplexProgramTarget_1	Like ComplexProgramTarget, but uses SRCS1,
			OBJS1, and DEPLIBS1 and can be used with
			ComplexProgramTarget_2 and ComplexProgramTarget_3
			to build up to three programs in the same directory.
			Set PROGRAMS to the programs built by all of
			these rules.  For more than 3 programs, use
			NormalProgramTarget for each.
ComplexProgramTarget_2	Use after ComplexProgramTarget_1 for the
			second program in a directory.  Uses SRCS2,
			OBJS2, and DEPLIBS2.
ComplexProgramTarget_3	Use after ComplexProgramTarget_2 for the
			third program in a directory.  Uses SRCS3,
			OBJS3, and DEPLIBS3.

NormalProgramTarget	Build a program.  Can be used multiple times
			with different arguments in the same Imakefile.

Lower level rules, often used with NormalProgramTarget

InstallProgram		install a program.

InstallManPage		install a manual page.

InstallDirectory	install a directory.

DependTarget()		include once at end of Imakefile with
			NormalProgramTarget rules or that uses Library.tmpl.
			Generates dependencies for files named in SRCS.

Manual page rules, commonly used only in special documentation directories:

InstallManPage
InstallManPageLong
InstallManPageAliases

Other rules:

SpecialCObjectRule	Compile a C file with special flags.
AllTarget		Declare additional targets to build.
InstallAppDefaults	Install X application defaults file.

Imakefile for directory with subdirectories

XCOMM this is a sample Imakefile for a directory containing subdirectories
#define IHaveSubdirs
#define PassCDebugFlags CDEBUGFLAGS="$(CDEBUGFLAGS)"
SUBDIRS = list of subdirs ...
MakeSubdirs($(SUBDIRS))
DependSubdirs($(SUBDIRS))


Common Targets

These targets are typically NOT defined explicitly by the Imakefile
writer; rather they are generated automatically by imake rules.
They are listed here for the convenience of people using the resulting
Makefile, not people writing the original Imakefile.

all			Default rule; builds whatever is in this directory.
Makefile		Remake the Makefile (use after changing Imakefile).
			Run "make depend" after.
Makefiles		Remake all Makefiles in subdirectories.  (Does
			nothing if no subdirectories.)
			Run "make depend" after.
includes		Generate and install in the tree any necessary
			header files.
depend			Update dependencies in the Makefile calculated
			by examining the source files.
install			Install what "make all" built on the system.
install.man		Install manual pages.
clean			Remove built objects and other derived files.
lint			Run lint.
tags			Create a tags file.
