# -*- make -*-

|

# This file configures the default environment for the make system
|
|||
# The way it works is fairly simple, each module is defined in it's
|
|||
# own *.mak file. It expects a set of variables to be set to values
|
|||
# for it to operate as expected. When included the module generates
|
|||
# the requested rules based on the contents of its control variables.
|
|||
|
|||
# This works out very well and allows a good degree of flexability.
|
|||
# To accomidate some of the features we introduce the concept of
|
|||
# local variables. To do this we use the 'Computed Names' feature of
|
|||
# gmake. Each module declares a LOCAL scope and access it with,
|
|||
# $($(LOCAL)-VAR)
|
|||
# This works very well but it is important to rembember that within
|
|||
# a rule the LOCAL var is unavailble, it will have to be constructed
|
|||
# from the information in the rule invokation. For stock rules like
|
|||
# clean this is simple, we use a local clean rule called clean/$(LOCAL)
|
|||
# and then within the rule $(@F) gets back $(LOCAL)! Other rules will
|
|||
# have to use some other mechanism (filter perhaps?) The reason such
|
|||
# lengths are used is so that each directory can contain several 'instances'
|
|||
# of any given module
|
|||
|
|||
# A build directory is used by default, all generated items get put into
|
|||
# there. However unlike automake this is not done with a VPATH build
|
|||
# (vpath builds break the distinction between #include "" and #include <>)
|
|||
# but by explicly setting the BUILD variable. Make is invoked from
|
|||
# within the source itself which is much more compatible with compilation
|
|||
# environments.
