If nothing was +# specified when calling configure, it searches first in /usr/local +# and then in /usr. If the --with-zlib=DIR is specified, it will try +# to find it in DIR/include/zlib.h and DIR/lib/libz.a. If +# --without-zlib is specified, the library is not searched at all. +# +# If either the header file (zlib.h) or the library (libz) is not +# found, the configuration exits on error, asking for a valid zlib +# installation directory or --without-zlib. +# +# The macro defines the symbol HAVE_LIBZ if the library is found. You +# should use autoheader to include a definition for this symbol in a +# config.h file. Sample usage in a C/C++ source is as follows: +# +# #ifdef HAVE_LIBZ +# #include +# #endif /* HAVE_LIBZ */ +# +# LAST MODIFICATION +# +# 2004-09-20 +# +# COPYLEFT +# +# Copyright (c) 2004 Loic Dachary +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of the +# License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
