Installation of libxml2
Install libxml2 by running the
following commands:
./configure --prefix=/usr \
--sysconfdir=/etc \
--disable-static \
--with-history \
--with-icu \
PYTHON=/usr/bin/python3 \
--docdir=/usr/share/doc/libxml2-2.13.4 &&
make
If you downloaded the test suite, issue the following command:
tar xf ../xmlts20130923.tar.gz
To test the results, issue: make
check > check.log. This command will print
several lines of error messages like “Failed to
parse xstc/...
” because some test files are
missing and these messages can be safely ignored. A summary of the
results can be obtained with grep -E
'^Total|expected|Ran' check.log. If Valgrind-3.23.0 is
installed and you want to check for memory leaks, replace
check with
check-valgrind.
Note
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
Finally, prevent some packages from unnecessarily linking to ICU
using the following commands as the root
user:
rm -vf /usr/lib/libxml2.la &&
sed '/libs=/s/xml2.*/xml2"/' -i /usr/bin/xml2-config
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-icu
: This switch
enables support for ICU, which
provides additional Unicode support. This is needed for some
packages in BLFS, such as for QtWebEngine.
PYTHON=/usr/bin/python3
:
Allows building the libxml2 module with Python3 instead of Python2.
