  2                         Expat, Release 2.1.0
  3 
  4 This is Expat, a C library for parsing XML, written by James Clark.
  5 Expat is a stream-oriented XML parser.  This means that you register
  6 handlers with the parser before starting the parse.  These handlers
  7 are called when the parser discovers the associated structures in the
  8 document being parsed.  A start tag is an example of the kind of
  9 structures for which you may register handlers.
 10 
 11 Windows users should use the expat_win32bin package, which includes
 12 both precompiled libraries and executables, and source code for
 13 developers.
 14 
 15 Expat is free software.  You may copy, distribute, and modify it under
 16 the terms of the License contained in the file COPYING distributed
 17 with this package.  This license is the same as the MIT/X Consortium
 18 license.
 19 
 20 Versions of Expat that have an odd minor version (the middle number in
 21 the release above), are development releases and should be considered
 22 as beta software.  Releases with even minor version numbers are
 23 intended to be production grade software.
 24 
 25 If you are building Expat from a check-out from the CVS repository,
 26 you need to run a script that generates the configure script using the
 27 GNU autoconf and libtool tools.  To do this, you need to have
 28 autoconf 2.58 or newer. Run the script like this:
 29 
 30         ./buildconf.sh
 31 
 32 Once this has been done, follow the same instructions as for building
 33 from a source distribution.
 34 
 35 To build Expat from a source distribution, you first run the
 36 configuration shell script in the top level distribution directory:
 37 
 38         ./configure
 39 
 40 There are many options which you may provide to configure (which you
 41 can discover by running configure with the --help option).  But the
 42 one of most interest is the one that sets the installation directory.
 43 By default, the configure script will set things up to install
 44 libexpat into /usr/local/lib, expat.h into /usr/local/include, and
 45 xmlwf into /usr/local/bin.  If, for example, you'd prefer to install
 46 into /home/me/mystuff/lib, /home/me/mystuff/include, and
 47 /home/me/mystuff/bin, you can tell configure about that with:
 48 
 49         ./configure --prefix=/home/me/mystuff
 50         
 51 Another interesting option is to enable 64-bit integer support for
 52 line and column numbers and the over-all byte index:
 53 
 54         ./configure CPPFLAGS=-DXML_LARGE_SIZE
 55         
 56 However, such a modification would be a breaking change to the ABI
 57 and is therefore not recommended for general use - e.g. as part of
 58 a Linux distribution - but rather for builds with special requirements.
 59 
 60 After running the configure script, the "make" command will build
 61 things and "make install" will install things into their proper
 62 location.  Have a look at the "Makefile" to learn about additional
 63 "make" options.  Note that you need to have write permission into
 64 the directories into which things will be installed.
 65 
 66 If you are interested in building Expat to provide document
 67 information in UTF-16 encoding rather than the default UTF-8, follow
 68 these instructions (after having run "make distclean"):
 69 
 70         1. For UTF-16 output as unsigned short (and version/error
 71            strings as char), run:
 72 
 73                ./configure CPPFLAGS=-DXML_UNICODE
 74 
 75            For UTF-16 output as wchar_t (incl. version/error strings),
 76            run:
 77 
 78                ./configure CFLAGS="-g -O2 -fshort-wchar" \
 79                            CPPFLAGS=-DXML_UNICODE_WCHAR_T
 80 
 81         2. Edit the MakeFile, changing:
 82 
 83                LIBRARY = libexpat.la
 84 
 85            to:
 86 
 87                LIBRARY = libexpatw.la
 88 
 89            (Note the additional "w" in the library name.)
 90 
 91         3. Run "make buildlib" (which builds the library only).
 92            Or, to save step 2, run "make buildlib LIBRARY=libexpatw.la".
 93 
 94         4. Run "make installlib" (which installs the library only).
 95            Or, if step 2 was omitted, run "make installlib LIBRARY=libexpatw.la".
 96            
 97 Using DESTDIR or INSTALL_ROOT is enabled, with INSTALL_ROOT being the default
 98 value for DESTDIR, and the rest of the make file using only DESTDIR.
 99 It works as follows:
100    $ make install DESTDIR=/path/to/image
101 overrides the in-makefile set DESTDIR, while both
102    $ INSTALL_ROOT=/path/to/image make install
103    $ make install INSTALL_ROOT=/path/to/image
104 use DESTDIR=$(INSTALL_ROOT), even if DESTDIR eventually is defined in the
105 environment, because variable-setting priority is
106 1) commandline
107 2) in-makefile
108 3) environment  
109 
110 Note: This only applies to the Expat library itself, building UTF-16 versions
111 of xmlwf and the tests is currently not supported.         
112 
113 Note for Solaris users:  The "ar" command is usually located in
114 "/usr/ccs/bin", which is not in the default PATH.  You will need to
115 add this to your path for the "make" command, and probably also switch
116 to GNU make (the "make" found in /usr/ccs/bin does not seem to work
117 properly -- appearantly it does not understand .PHONY directives).  If
118 you're using ksh or bash, use this command to build:
119 
120         PATH=/usr/ccs/bin:$PATH make
121 
122 When using Expat with a project using autoconf for configuration, you
123 can use the probing macro in conftools/expat.m4 to determine how to
124 include Expat.  See the comments at the top of that file for more
125 information.
