# Definitions common to all subsystem makefiles.
# All of Aladdin's products use a common scheme for their makefiles.
# Products are built out of one or more subsystems.
# Each subsystem has its own source directory, which includes a makefile
# for that subsystem.
# All makefiles have a common structure, shown here in the form of a tree
# in which the edges are created by 'include' statements:
#
# 1. Top-level makefile:
# << Parameter and directory definitions >>
# 2. Definitions for top-level products built using a
# particular OS/compiler combinations:
# 3. Definitions for a particular compiler;
# 4. Definitions for a particular OS;
# 5. Generic definitions (this file);
# << rules >>
# 6. Makefiles for each subsystem;
# 7. Definitions and rules for the product.
#
# The following table shows the dependencies of each makefile on the
# different configuration variables, and also indicates in which directory
# the makefile is normally located:
#
# Prod. Subsys. OS Compiler directory
# 1 X X X X product source
# 2 X X common
# 3 X common
# 4 X common
# 5 common
# 6 X subsystem source
# 7 X product source
#
# Currently, the product and subsystem source directories are the same,
# but there is no logical requirement for this and it may change in
# the future.
#
# Each makefile in the tree must provide certain definitions for makefiles
# that follow it in the traversal (execution) order, since some versions
# of 'make' expand macros eagerly rather than lazily. Here are the
# definitions that each makefile must provide. See the individual
# makefiles for more detailed descriptions.
#
# 1 MAKEFILE, <subsys>DIR for each subsystem, TARGET_XE
# 2 (rule for building executable)
# 3 CC_
# 4 D, OBJ, C_, I_, II, _I, O_, XE, CP_, RM_, RMN_
# 5 GS_XE, ECHOGS_XE, SETMOD, ADDMOD
# 6 <subsys>_MAK
# 7 (default rule)
#
# Here are some examples of the 7 different makefile types that may be
# helpful in understanding the structure:
#
# 1 pcl/pcl_ugcc.mak
# 2 common/ugcc_top.mak
# 3 common/gccdefs.mak
# 4 common/unixdefs.mak
# 5 common/generic.mak
# 6 pcl/pcl.mak
# 7 pcl/pcl_top.mak
# Define the Ghostscript executable.
# Currently it always lives in the GLOBJ directory.
GS_XE=$(GLOBJDIR)$(D)gs$(XE)
# Define the echogs executable.
# Currently it always lives in the GLOBJ directory.
ECHOGS_XE=$(GLOBJDIR)$(D)echogs$(XE)
# Define the commands for building module descriptions.
SETMOD=$(ECHOGS_XE) -e .dev -w- -Q-obj
ADDMOD=$(ECHOGS_XE) -e .dev -a-
