  1. Expat, Release 2.0.1
  2. This is Expat, a C library for parsing XML, written by James Clark.
  3. Expat is a stream-oriented XML parser. This means that you register
  4. handlers with the parser before starting the parse. These handlers
  5. are called when the parser discovers the associated structures in the
  6. document being parsed. A start tag is an example of the kind of
  7. structures for which you may register handlers.
  8. Windows users should use the expat_win32bin package, which includes
  9. both precompiled libraries and executables, and source code for
  10. developers.
  11. Expat is free software. You may copy, distribute, and modify it under
  12. the terms of the License contained in the file COPYING distributed
  13. with this package. This license is the same as the MIT/X Consortium
  14. license.
  15. Versions of Expat that have an odd minor version (the middle number in
  16. the release above), are development releases and should be considered
  17. as beta software. Releases with even minor version numbers are
  18. intended to be production grade software.
  19. If you are building Expat from a check-out from the CVS repository,
  20. you need to run a script that generates the configure script using the
  21. GNU autoconf and libtool tools. To do this, you need to have
  22. autoconf 2.52 or newer and libtool 1.4 or newer (1.5 or newer preferred).
  23. Run the script like this:
  24. ./buildconf.sh
  25. Once this has been done, follow the same instructions as for building
  26. from a source distribution.
  27. To build Expat from a source distribution, you first run the
  28. configuration shell script in the top level distribution directory:
  29. ./configure
  30. There are many options which you may provide to configure (which you
  31. can discover by running configure with the --help option). But the
  32. one of most interest is the one that sets the installation directory.
  33. By default, the configure script will set things up to install
  34. libexpat into /usr/local/lib, expat.h into /usr/local/include, and
  35. xmlwf into /usr/local/bin. If, for example, you'd prefer to install
  36. into /home/me/mystuff/lib, /home/me/mystuff/include, and
  37. /home/me/mystuff/bin, you can tell configure about that with:
  38. ./configure --prefix=/home/me/mystuff
  39. Another interesting option is to enable 64-bit integer support for
  40. line and column numbers and the over-all byte index:
  41. ./configure CPPFLAGS=-DXML_LARGE_SIZE
  42. However, such a modification would be a breaking change to the ABI
  43. and is therefore not recommended for general use - e.g. as part of
  44. a Linux distribution - but rather for builds with special requirements.
  45. After running the configure script, the "make" command will build
  46. things and "make install" will install things into their proper
  47. location. Have a look at the "Makefile" to learn about additional
  48. "make" options. Note that you need to have write permission into
  49. the directories into which things will be installed.
  50. If you are interested in building Expat to provide document
  51. information in UTF-16 rather than the default UTF-8, follow these
  52. instructions (after having run "make distclean"):
  53. 1. For UTF-16 output as unsigned short (and version/error
  54. strings as char), run:
  55. ./configure CPPFLAGS=-DXML_UNICODE
  56. For UTF-16 output as wchar_t (incl. version/error strings),
  57. run:
  58. ./configure CFLAGS="-g -O2 -fshort-wchar" \
  59. CPPFLAGS=-DXML_UNICODE_WCHAR_T
  60. 2. Edit the MakeFile, changing:
  61. LIBRARY = libexpat.la
  62. to:
  63. LIBRARY = libexpatw.la
  64. (Note the additional "w" in the library name.)
  65. 3. Run "make buildlib" (which builds the library only).
  66. Or, to save step 2, run "make buildlib LIBRARY=libexpatw.la".
  67. 4. Run "make installlib" (which installs the library only).
  68. Or, if step 2 was omitted, run "make installlib LIBRARY=libexpatw.la".
  69. Using DESTDIR or INSTALL_ROOT is enabled, with INSTALL_ROOT being the default
  70. value for DESTDIR, and the rest of the make file using only DESTDIR.
  71. It works as follows:
  72. $ make install DESTDIR=/path/to/image
  73. overrides the in-makefile set DESTDIR, while both
  74. $ INSTALL_ROOT=/path/to/image make install
  75. $ make install INSTALL_ROOT=/path/to/image
  76. use DESTDIR=$(INSTALL_ROOT), even if DESTDIR eventually is defined in the
  77. environment, because variable-setting priority is
  78. 1) commandline
  79. 2) in-makefile
  80. 3) environment
  81. Note for Solaris users: The "ar" command is usually located in
  82. "/usr/ccs/bin", which is not in the default PATH. You will need to
  83. add this to your path for the "make" command, and probably also switch
  84. to GNU make (the "make" found in /usr/ccs/bin does not seem to work
  85. properly -- appearantly it does not understand .PHONY directives). If
  86. you're using ksh or bash, use this command to build:
  87. PATH=/usr/ccs/bin:$PATH make
  88. When using Expat with a project using autoconf for configuration, you
  89. can use the probing macro in conftools/expat.m4 to determine how to
  90. include Expat. See the comments at the top of that file for more
  91. information.
  92. A reference manual is available in the file doc/reference.html in this
  93. distribution.
  94. The homepage for this project is http://www.libexpat.org/. There
  95. are links there to connect you to the bug reports page. If you need
  96. to report a bug when you don't have access to a browser, you may also
  97. send a bug report by email to expat-bugs@mail.libexpat.org.
  98. Discussion related to the direction of future expat development takes
  99. place on expat-discuss@mail.libexpat.org. Archives of this list and
  100. other Expat-related lists may be found at:
