# makefile for Independent JPEG Group code.
# NOTE: This makefile is only known to work with versions 5, 5a, and 5b of the
# IJG code. You can get the current version by Internet anonymous FTP from
# ftp.uu.net:/graphics/jpeg. As of April 11, 1995, version 5b is
# the current version, and the IJG files are named:
# jpegsrc.v5b.tar.gz Standard distribution
# jpeg-5b.zip DOS-style archive
# You may find more recent files on the FTP server. If the version number,
# and hence the subdirectory name, has changed, you will probably want to
# change the definition of JSRCDIR (in the platform-specific makefile,
# not here) to reflect this, since that way you can use the IJG archive
# without change.
#
# NOTE: For some obscure reason (probably a bug in djtarx), if you are
# compiling on a DesqView/X system, you should use the zip version of the
# IJG library, not the tar.gz version.
# JSRCDIR is defined in the platform-specific makefile, not here.

# We keep all of the IJG code in a separate directory so as not to
# inadvertently mix it up with Aladdin Enterprises' own code.
# However, we need our own version of jconfig.h, and our own "wrapper" for
# jmorecfg.h. We also need a substitute for jerror.c, in order to
# keep the error strings out of the automatic data segment in
# 16-bit environments. We currently also need our own version of jpeglib.h
# in order to change MAX_BLOCKS_IN_MCU for Adobe compatibility.

# and all .h files that include either of these files, directly or
# indirectly. The only such .h files currently are jinclude.h and jpeglib.h.
# (Currently, we supply our own version of jpeglib.h -- see above.)
# Also, to avoid including the JSRCDIR directory name in our source files,
# we must also copy up any other .h files that our own code references.
# Currently, the only such .h files are jerror.h and jversion.h.

# In order to avoid having to keep the dependency lists for the IJG code
