Optional

Doxygen-1.10.0, git-2.44.0, librsvg-2.57.1, Valgrind-3.22.0 (optional for some tests), and pytest-8.0.0 with python-libevdev and pyudev

Installation of libwacom

Install libwacom by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..            \
      --prefix=/usr       \
      --buildtype=release \
      -Dtests=disabled    &&
ninja

To test the results, issue: ninja test. To run additional tests, install pytest-8.0.0, python-libevdev, and pyudev, then remove the "-Dtests=disabled" option from the meson line above.

Now, as the root user: 

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Dtests=disabled: This parameter disables some of the more advanced tests because they require pytest-8.0.0 and other two Python modules beyond the scope of BLFS to work properly.
