# prevent multiple inclusions

# NB: This file is internally protected against multiple inclusions.
# But for perfomance reasons, you might want to check the
# RULES_MAKE_LOADED variable yourself and include this file only if it
# is empty.  That allows make to skip reading the file entirely when it

#
# Quick explanation - 
#
# Say that you run `make all'.  The rule for `all' is below here, and
# depends on internal-all.  Rules for internal-all are found in
# tool.make, library.make etc; there, internal-all will depend on a
# list of appropriate %.variables targets, such as
# gsdoc.tool.all.variables <which means we need to make `all' for the
# `tool' called `gsdoc'> - to process these prerequisites, the
# %.variables rule below is used.  this rule gets an appropriate make
# subprocess going, with the task of building that specific
# target-type-operation prerequisite.  The make subprocess will be run
# as in `make internal-tool-all INTERNAL_tool_NAME=gsdoc ...<and other
# variables>' and this make subprocess wil find the internal-tool-all
# rule in tool.make, and execute that, building the tool.
#
# Hint: run make with `make -n' to see the recursive method invocations 
#       with the parameters used
#

#
# Global targets
#

# The first time you invoke `make', if you have not given a target,
# `all' is executed as it is the first one.

# In exceptional conditions, you might need to want to use different compiler
# flags for a file (for example, if a file doesn't compile with optimization
# turned on, you might want to compile that single file with optimizations
# turned off).  gnustep-make allows you to do this - you can specify special 
# flags to be used when compiling a *specific* file in two ways - 
#
# xxx_FILE_FLAGS (where xxx is the file name, such as main.m) 
#                are special compilation flags to be used when compiling xxx
#
# xxx_FILE_FILTER_OUT_FLAGS (where xxx is the file name, such as mframe.m)
#                is a filter-out make pattern of flags to be filtered out 
#                from the compilation flags when compiling xxx.
#
# Typical examples:
#
# Disable optimization flags for the file NSInvocation.m:
# NSInvocation.m_FILE_FILTER_OUT_FLAGS = -O%
#
# Disable optimization flags for the same file, and also remove 
# -fomit-frame-pointer:
# NSInvocation.m_FILE_FILTER_OUT_FLAGS = -O% -fomit-frame-pointer
#
# Force the compiler to warn for #import if used in file file.m:
# file.m_FILE_FLAGS = -Wimport
# file.m_FILE_FILTER_OUT_FLAGS = -Wno-import
#

# Please don't be scared by the following rules ... In normal
# situations, $<_FILTER_OUT_FLAGS is empty, and $<_FILE_FLAGS is empty

# Prevent make from trying to remove stuff like
# libcool.library.all.subprojects thinking that it is a temporary file
.PRECIOUS: %.variables %.tools %.subprojects

#
## The magical %.variables rules, thank you GNU make!
#

# The %.variables target has to be called with the name of the actual
# target, followed by the operation, then the makefile fragment to be
# called and then the variables word. Suppose for example we build the
# library libgmodel, the target should look like:
#
#	libgmodel.all.library.variables
#
# when the rule is executed, $* is libgmodel.all.libray;
#  target will be libgmodel
#  operation will be all
#  type will be library 
#
# this rule might be executed many times, for different targets to build.

# the rule then calls a submake, which runs the real code

# the following is the code used in %.variables, %.tools and %.subprojects
# to extract the target, operation and type from the $* (the stem) of the 
# rule.  with GNU make => 3.78, we could define the following as macros 
# and use $(call ...) to call them; but because we have users who are using 
# GNU make older than that, we have to manually `paste' this code 
# wherever we need to access target or type or operation.
#
# Anyway, the following table tells you what these commands do - 
#
# target=$(basename $(basename $(1)))
# operation=$(subst .,,$(suffix $(basename $(1))))
# type=$(subst -,_,$(subst .,,$(suffix $(1))))
#
# It's very important to notice that $(basename $(basename $*)) in
# these rules is simply the target (such as libgmodel).

# Before building the real thing, we must build framework tools if
# any, then subprojects (FIXME - not sure - at what stage should we
# build framework tools ? perhaps after the framework so we can link
# with it ?)
