Introduction to libxml2

The libxml2 package contains libraries and utilities used for parsing XML files.

This package is known to build and work properly using an LFS-10.0 platform.

libxml2 Dependencies





Some packages which utilize libxml2 (such as GNOME Doc Utils) need the Python3 module installed to function properly and some packages will not build properly if the Python3 module is not available.

The old Python2 module can be built after has been installed, see Python2 libxml2-2.9.10 module.


ICU-67.1 and Valgrind-3.16.1 (may be used in the tests)

User Notes:

Installation of libxml2

If you are going to run the tests, disable one test that prevents the tests from completing:

sed -i 's/test.test/#&/' python/tests/

Install libxml2 by running the following commands:

./configure --prefix=/usr    \
            --disable-static \
            --with-history   \
            --with-python=/usr/bin/python3 &&

If you downloaded the testsuite, issue the following command:

tar xf ../xmlts20130923.tar.gz

To test the results, issue: make check > check.log. A summary of the results can be obtained with grep -E '^Total|expected' check.log. If Valgrind-3.16.1 is installed and you want to check memory leaks, replace check with check-valgrind.



The tests use http://localhost/ to test parsing of external entities. If the machine where you run the tests serves as a web site, the tests may hang, depending on the content of the file served. It is therefore recommended to shut down the server during the tests, as the root user:

/etc/init.d/httpd stop

Now, as the root user:

make install

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.

--with-history: This switch enables Readline support when running xmlcatalog or xmllint in shell mode.

--with-python=/usr/bin/python3: Allows building the libxml2 module with Python3 instead of Python2.

--with-icu: Add this switch if you have built ICU-67.1, for better unicode support.

--with-threads: Add this switch to enable multithread support.
