Chapter 9. General Libraries

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-7.10 platform.

Package Information

Additional Downloads

libxml2 Dependencies

Recommended

Python-2.7.12 or Python-3.5.2 (to build and install a Python library module, additionally it is required to run the full suite of tests)

[Note]

Note

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

Valgrind-3.11.0 (may be used in the tests)

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/libxml2

Installation of libxml2

Install libxml2 by running the following commands: 

sed -i "/seems to be moved/s/^/#/" ltmain.sh &&
./configure --prefix=/usr --disable-static --with-history &&
make

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-3.11.0 is installed and you want to check memory leaks, replace check with check-valgrind.

Now, as the root user: 

make install

Command Explanations

sed -i ...: This sed prevents many useless warnings from being issued from libtool.

--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: Add this switch if you want libxml2 to use Python3 instead of Python2.
