# Generic makefile, common to all platforms.
# The platform-specific makefiles `include' this file.
# They define the following symbols:
# GS - the name of the executable (without the extension, if any).
# GS_LIB_DEFAULT - the default directory/ies for searching for the
# initialization and font files at run time.
# SEARCH_HERE_FIRST - the default setting of -P (whether or not to
# look for files in the current directory first).
# GS_DOCDIR - the directory where documentation will be available
# at run time.
# JSRCDIR - the directory where the IJG JPEG library source code
# is stored (at compilation time).
# JVERSION - the major version number of the IJG JPEG library.
# PSRCDIR, PVERSION - the same for libpng.
# ZSRCDIR - the same for zlib.
# SHARE_LIBPNG - normally 0; if set to 1, asks the linker to use
# an existing compiled libpng (-lpng) instead of compiling and
# linking libpng explicitly.
# LIBPNG_NAME, the name of the shared libpng, currently always
# png (libpng, -lpng).
# SHARE_ZLIB - normally 0; if set to 1, asks the linker to use
# an existing compiled zlib (-lgz or -lz) instead of compiling
# and linking libgz/libz explicitly.
# ZLIB_NAME - the name of the shared zlib, either gz (for libgz, -lgz)
# or z (for libz, -lz).
# CONFIG - a configuration ID, added at the request of a customer,
# that is supposed to help in maintaining multiple variants in
# a single directory. Normally this is an empty string;
# it may be any string that is legal as part of a file name.
# DEVICE_DEVS - the devices to include in the executable.
# See devs.mak for details.
# DEVICE_DEVS1...DEVICE_DEVS15 - additional devices, if the definition
# of DEVICE_DEVS doesn't fit on one line. See devs.mak for details.
# FEATURE_DEVS - what features to include in the executable.
# Normally this is one of:
# level1 - a standard PostScript Level 1 language
# interpreter.
# level2 - a standard PostScript Level 2 language
# interpreter.
# pdf - a PDF-capable interpreter.
# You may include both level1 and pdf, or both level2 and pdf.
# The following feature may be added to either of the standard
# configurations:
# ccfonts - precompile fonts into C, and link them
# with the executable. See fonts.txt for details.
# The remaining features are of interest primarily to developers
# who want to "mix and match" features to create custom
# configurations:
# dps - (partial) support for Display PostScript extensions:
# see language.txt for details.
# btoken - support for binary token encodings.
# Included automatically in the dps and level2 features.
# cidfont - (currently partial) support for CID-keyed fonts.
# color - support for the Level 1 CMYK color extensions.
# Included automatically in the dps and level2 features.
# compfont - support for composite (type 0) fonts.
# Included automatically in the level2 feature.
# dct - support for DCTEncode/Decode filters.
# Included automatically in the level2 feature.
# epsf - support for recognizing and skipping the binary
# header of MS-DOS EPSF files.
# filter - support for Level 2 filters (other than eexec,
# ASCIIHexEncode/Decode, NullEncode, PFBDecode,
# RunLengthEncode/Decode, and SubFileDecode, which are
# always included, and DCTEncode/Decode,
# which are separate).
# Included automatically in the level2 feature.
# fzlib - support for zlibEncode/Decode filters.
# ttfont - support for TrueType fonts.
# type1 - support for Type 1 fonts and eexec;
# normally included automatically in all configurations.
# type42 - support for Type 42 (embedded TrueType) fonts.
# Included automatically in the level2 feature.
# There are quite a number of other sub-features that can be
# selectively included in or excluded from a configuration,
# but the above are the ones that are most likely to be of
# interest.
# COMPILE_INITS - normally 0; if set to 1, compiles the PostScript
# language initialization files (gs_init.ps et al) into the
# executable, eliminating the need for these files to be present
# at run time.
# BAND_LIST_STORAGE - normally file; if set to memory, stores band
# lists in memory (with compression if needed).
# BAND_LIST_COMPRESSOR - normally zlib: selects the compression method
# to use for band lists in memory.
# FILE_IMPLEMENTATION - normally stdio; if set to fd, uses file
# descriptors instead of buffered stdio for file I/O; if set to
# both, provides both implementations with different procedure
# names for the fd-based implementation (see sfxfd.c for
# more information).
# EXTEND_NAMES - a value N between 0 and 6, indicating that the name
# table should have a capacity of 2^(16+N) names. This normally
# should be set to 0 (or left undefined), since non-zero values
# result in a larger fixed space overhead and slightly slower code.
# EXTEND_NAMES is ignored in 16-bit environments.
#
# It is very unlikely that anyone would want to edit the remaining
# symbols, but we describe them here for completeness:
# GS_INIT - the name of the initialization file for the interpreter,
# normally gs_init.ps.
# PLATFORM - a "device" name for the platform, so that platforms can
# add various kinds of resources like devices and features.
# CMD - the suffix for shell command files (e.g., null or .bat).
# (This is only needed in a few places.)
# D - the directory separator character (\ for MS-DOS, / for Unix).
# O - the string for specifying the output file from the C compiler
# (-o for MS-DOS, -o ./ for Unix).
# OBJ - the extension for relocatable object files (e.g., o or obj).
# XE - the extension for executable files (e.g., null or .exe).
# XEAUX - the extension for the executable files (e.g., null or .exe)
# for the utility programs (ansi2knr and those compiled with
# CCAUX).
# BEGINFILES - the list of files that `make begin' and `make clean'
# should delete.
# CCA2K - the C invocation for the ansi2knr program, which is the only
# one that doesn't use ANSI C syntax. (It is only needed if
# the main C compiler also isn't an ANSI compiler.)
# CCAUX - the C invocation for auxiliary programs (echogs, genarch,
# genconf, geninit).
# CCBEGIN - the compilation command for `make begin', normally
# $(CCC) *.c.
# CCC - the C invocation for normal compilation.
# CCD - the C invocation for files that store into frame buffers or
# device registers. Needed because some optimizing compilers
# will eliminate necessary stores.
# CCCF - the C invocation for compiled fonts and other large,
# self-contained data modules. Needed because MS-DOS
# requires using the 'huge' memory model for these.
# CCINT - the C invocation for compiling the main interpreter module,
# normally the same as CCC: this is needed because the
# Borland compiler generates *worse* code for this module
# (but only this module) when optimization (-O) is turned on.
# CCLEAF - the C invocation for compiling modules that contain only
# leaf procedures, which don't need to build stack frames.
# This is needed only because many compilers aren't able to
# recognize leaf procedures on their own.
# AK - if source files must be converted from ANSI to K&R syntax,
# this is $(ANSI2KNR_XE); if not, it is null.
# If a particular platform requires other utility programs
# to be built, AK must include them too.
# SHP - the prefix for invoking a shell script in the current directory
# (null for MS-DOS, $(SH) ./ for Unix).
# EXPP, EXP - the prefix for invoking an executable program in the
# current directory (null for MS-DOS, ./ for Unix).
# SH - the shell for scripts (null on MS-DOS, sh on Unix).
# CONFILES - the arguments for genconf to generate the appropriate
# linker control files (various).
# CP_ - the command for copying one file to another. Because of
# limitations in the MS-DOS/MS Windows environment, the
# second argument must either be '.' (in which case the
# write date may be either preserved or set to the current
# date) or a file name (in which case the write date is
# always updated).
# RM_ - the command for deleting (a) file(s) (including wild cards,
# but limited to a single file or pattern).
# RMN_ = the command for deleting multiple files / patterns.
#
# The platform-specific makefiles must also include rules for creating
# certain dynamically generated files:
# gconfig_.h - this indicates the presence or absence of
# certain system header files that are located in different
# places on different systems. (It could be generated by
# the GNU `configure' program.)
# gconfigv.h - this indicates the status of certain machine-
# and configuration-specific features derived from definitions
# in the platform-specific makefile.
# Define the name of this makefile.

######################## How to define new 'features' #######################
#
# One defines new 'features' exactly like devices (see devs.mak for details).
# For example, one would define a feature abc by adding the following to
# gs.mak:
#
# abc_=abc1.$(OBJ) ...
# abc.dev: $(GS_MAK) $(ECHOGS_XE) $(abc_)
# $(SETMOD) abc $(abc_)
# $(ADDMOD) abc -obj ... [if needed]
# $(ADDMOD) abc -oper ... [if appropriate]
# $(ADDMOD) abc -ps ... [if appropriate]
#
# If the abc feature requires the presence of some other features jkl and
# pqr, then the rules must look like this:
#
# abc_=abc1.$(OBJ) ...
# abc.dev: $(GS_MAK) $(ECHOGS_XE) $(abc_) jkl.dev pqr.dev
# $(SETMOD) abc $(abc_)
# ...
# $(ADDMOD) abc -include jkl pqr
# --------------------- Configuration-dependent files --------------------- #
# gconfig.h shouldn't have to depend on DEVS_ALL, but that would
# involve rewriting gsconfig to only save the device name, not the
# contents of the <device>.dev files.
# FEATURE_DEVS must precede DEVICE_DEVS so that devices can override
# features in obscure cases.
