2 Expat, Release 2.0.0 |
|
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 2.52 or newer and libtool 1.4 or newer. Run the script like |
|
29 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 After running the configure script, the "make" command will build |
|
58 things and "make install" will install things into their proper |
|
59 location. Have a look at the "Makefile" to learn about additional |
|
60 "make" options. Note that you need to have write permission into |
|
61 the directories into which things will be installed. |
|
62 |
|
63 If you are interested in building Expat to provide document |
|
64 information in UTF-16 rather than the default UTF-8, follow these |
|
65 instructions: |
|
66 |
|
67 1. For UTF-16 output as unsigned short (and version/error |
|
68 strings as char), run: |
|
69 |
|
70 ./configure CPPFLAGS=-DXML_UNICODE |
|
71 |
|
72 For UTF-16 output as wchar_t (incl. version/error strings), |
|
73 run: |
|
74 |
|
75 ./configure CFLAGS="-g -O2 -fshort-wchar" \ |
|
76 CPPFLAGS=-DXML_UNICODE_WCHAR_T |
|
77 |
|
78 2. Edit the MakeFile, changing: |
|
79 |
|
80 LIBRARY = libexpat.la |
|
81 |
|
82 to: |
|
83 |
|
84 LIBRARY = libexpatw.la |
|
85 |
|
86 (Note the additional "w" in the library name.) |
|
87 |
|
88 3. Run "make buildlib" (which builds the library only). |
|
89 |
|
90 4. Run "make installlib" (which installs the library only). |
|
91 |
|
92 Note for Solaris users: The "ar" command is usually located in |
|
93 "/usr/ccs/bin", which is not in the default PATH. You will need to |
|
94 add this to your path for the "make" command, and probably also switch |
|
95 to GNU make (the "make" found in /usr/ccs/bin does not seem to work |
|
96 properly -- appearantly it does not understand .PHONY directives). If |
|
97 you're using ksh or bash, use this command to build: |
|
98 |
|
99 PATH=/usr/ccs/bin:$PATH make |
|
100 |
|
101 When using Expat with a project using autoconf for configuration, you |
|
102 can use the probing macro in conftools/expat.m4 to determine how to |
|
103 include Expat. See the comments at the top of that file for more |
|
104 information. |
