## Installation of ModemManager

Install ModemManager by running the following commands:

    ./configure --prefix=/usr                 \
                --sysconfdir=/etc             \
                --localstatedir=/var          \
                --disable-static              \
                --disable-maintainer-mode     \
                --with-systemd-journal        \
                --with-systemd-suspend-resume &&
    make

To test the results, issue: make check.

Now, as the `root` user:

    make install

## Command Explanations

`--with-systemd-journal` : This switch forces ModemManager to use the systemd journal for logging.

`--disable-static`: This switch prevents installation of static versions of the libraries.

`--enable-gtk-doc`: Use this parameter if GTK-Doc is installed and you wish to rebuild and install the API documentation.
