Installation of ModemManager

Install ModemManager by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..                 \
      --prefix=/usr            \
      --buildtype=release      \
      -D bash_completion=false \
      -D qrtr=false            &&
ninja

To test the results, issue: ninja test.

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.

-D bash_completion=false: Use this option if the external bash-completion package is not installed.

-D qrtr=false: This switch disables support for the QRTR protocol which needs the external libqrtr-glib package.

Configuring ModemManager
