1 2 Expat, Release 2.0.1 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 2.52 or newer and libtool 1.4 or newer (1.5 or newer preferred). 29 Run the script like this: 30 31 ./buildconf.sh 32 33 Once this has been done, follow the same instructions as for building 34 from a source distribution. 35 36 To build Expat from a source distribution, you first run the 37 configuration shell script in the top level distribution directory: 38 39 ./configure 40 41 There are many options which you may provide to configure (which you 42 can discover by running configure with the --help option). But the 43 one of most interest is the one that sets the installation directory. 44 By default, the configure script will set things up to install 45 libexpat into /usr/local/lib, expat.h into /usr/local/include, and 46 xmlwf into /usr/local/bin. If, for example, you'd prefer to install 47 into /home/me/mystuff/lib, /home/me/mystuff/include, and 48 /home/me/mystuff/bin, you can tell configure about that with: 49 50 ./configure --prefix=/home/me/mystuff 51 52 Another interesting option is to enable 64-bit integer support for 53 line and column numbers and the over-all byte index: 54 55 ./configure CPPFLAGS=-DXML_LARGE_SIZE 56 57 However, such a modification would be a breaking change to the ABI 58 and is therefore not recommended for general use - e.g. as part of 59 a Linux distribution - but rather for builds with special requirements. 60 61 After running the configure script, the "make" command will build 62 things and "make install" will install things into their proper 63 location. Have a look at the "Makefile" to learn about additional 64 "make" options. Note that you need to have write permission into 65 the directories into which things will be installed. 66 67 If you are interested in building Expat to provide document 68 information in UTF-16 rather than the default UTF-8, follow these 69 instructions (after having run "make distclean"): 70 71 1. For UTF-16 output as unsigned short (and version/error 72 strings as char), run: 73 74 ./configure CPPFLAGS=-DXML_UNICODE 75 76 For UTF-16 output as wchar_t (incl. version/error strings), 77 run: 78 79 ./configure CFLAGS="-g -O2 -fshort-wchar" \ 80 CPPFLAGS=-DXML_UNICODE_WCHAR_T 81 82 2. Edit the MakeFile, changing: 83 84 LIBRARY = libexpat.la 85 86 to: 87 88 LIBRARY = libexpatw.la 89 90 (Note the additional "w" in the library name.) 91 92 3. Run "make buildlib" (which builds the library only). 93 Or, to save step 2, run "make buildlib LIBRARY=libexpatw.la". 94 95 4. Run "make installlib" (which installs the library only). 96 Or, if step 2 was omitted, run "make installlib LIBRARY=libexpatw.la". 97 98 Using DESTDIR or INSTALL_ROOT is enabled, with INSTALL_ROOT being the default 99 value for DESTDIR, and the rest of the make file using only DESTDIR. 100 It works as follows: 101 $ make install DESTDIR=/path/to/image 102 overrides the in-makefile set DESTDIR, while both 103 $ INSTALL_ROOT=/path/to/image make install 104 $ make install INSTALL_ROOT=/path/to/image 105 use DESTDIR=$(INSTALL_ROOT), even if DESTDIR eventually is defined in the 106 environment, because variable-setting priority is 107 1) commandline 108 2) in-makefile 109 3) environment 110 111 Note for Solaris users: The "ar" command is usually located in 112 "/usr/ccs/bin", which is not in the default PATH. You will need to 113 add this to your path for the "make" command, and probably also switch 114 to GNU make (the "make" found in /usr/ccs/bin does not seem to work 115 properly -- appearantly it does not understand .PHONY directives). If 116 you're using ksh or bash, use this command to build: 117 118 PATH=/usr/ccs/bin:$PATH make 119 120 When using Expat with a project using autoconf for configuration, you 121 can use the probing macro in conftools/expat.m4 to determine how to 122 include Expat. See the comments at the top of that file for more 123 information. 124 125 A reference manual is available in the file doc/reference.html in this 126 distribution. 127 128 The homepage for this project is http://www.libexpat.org/. There 129 are links there to connect you to the bug reports page. If you need 130 to report a bug when you don't have access to a browser, you may also 131 send a bug report by email to expat-bugs (a] mail.libexpat.org. 132 133 Discussion related to the direction of future expat development takes 134 place on expat-discuss (a] mail.libexpat.org.
