# makefile for zlib library code.
|
|
|
18 |
# Users of this makefile must define the following:
|
|
|
19 |
# GSSRCDIR - the GS library source directory
|
|
|
20 |
# ZSRCDIR - the source directory
|
|
|
21 |
# ZGENDIR - the generated intermediate file directory
|
|
|
22 |
# ZOBJDIR - the object directory
|
|
|
23 |
# SHARE_ZLIB - 0 to compile zlib, 1 to share
|
|
|
24 |
# ZLIB_NAME - if SHARE_ZLIB=1, the name of the shared library
|
|
|
25 |
|
|
|
26 |
# This partial makefile compiles the zlib library for use in Ghostscript.
|
|
|
27 |
# You can get the source code for this library from:
|
|
|
28 |
# http://www.gzip.org/zlib/
|
|
|
29 |
# http://www.libpng.org/pub/png/src/
|
|
|
30 |
# zlib-#.#.#.tar.gz or zlib###.zip
|
|
|
31 |
# Please see Ghostscript's `Make.htm' file for instructions about how to
|
|
|
32 |
# unpack these archives.
|
|
|
33 |
#
|
|
|
34 |
# When each version of Ghostscript is released, we copy the associated
|
|
|
35 |
# version of the zlib library to
|
|
|
36 |
# ftp://ftp.cs.wisc.edu/ghost/3rdparty/
|
|
|
37 |
# for more convenient access.

# This makefile is known to work with zlib source version 1.2.1.
|
|
|
40 |
# It will only work with earlier versions (1.1.4) when SHARE_ZLIB=1.
|
|
|
41 |
# Note that there are obscure bugs in zlib versions before 1.1.3 that
|
|
|
42 |
# may cause the FlateDecode filter to produce an occasional ioerror
|
|
|
43 |
# and there is a serious security problem with 1.1.3: we strongly
|
|
|
44 |
# recommend using version 1.1.4 or later.
