libxml2-2.15.1

Introduction to libxml2

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

Important

Updating this package is known to break ABI.

Important

For the lib32 installation instructions, they require new Meson cross files from MLFS, as --libdir=/usr/lib32 has been moved to the cross files and no longer appear in the instructions. Install the new cross files so that 32-bit libraries don't get installed in /usr/lib.

libxml2 Dependencies

Recommended
ICU-78.2

Installation of libxml2

First, remove an unnecessary call to git in meson.build: 

sed -i "/'git'/,+3d" meson.build

Install libxml2 by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr       \
            --buildtype=release \
            -D history=enabled  \
            -D icu=enabled &&
ninja

Now, as the root user: 

ninja install &&
sed 's/--static/--shared/' -i /usr/bin/xml2-config

lib32 Installation of libxml2

Install lib32-libxml2 by running the following commands: 

rm -rf * &&
meson setup --prefix=/usr            \
            --buildtype=release      \
            --cross-file=lib32       \
            -D history=enabled       \
            -D icu=enabled &&
ninja

Now, as the root user: 

DESTDIR=$PWD/DESTDIR ninja install    &&
cp -Rv DESTDIR/usr/lib32/* /usr/lib32 &&
rm -rf DESTDIR                        &&
ldconfig

Command Explanations

Note

Inspect meson_options.txt or meson.options for a full list of options.

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

-D icu=enabled: This switch enables support for ICU, which provides additional Unicode support. This is needed for some packages outside of GLFS, such as for QtWebEngine.

Short Descriptions

xml2-config

determines the compile and linker flags that should be used to compile and link programs that use libxml2

xmlcatalog
