Library to easily handle, control and monitor cellular modems, using the ModemManager D-Bus API.

# compiler and libraries
sudo apt install build-essential libsdbus-c++-dev libsystemd-dev meson modemmanager-dev pkg-config

# for documentation
sudo apt install devhelp doxygen graphviz gtk-doc-tools \
        modemmanager-doc libmm-glib-doc network-manager-dev libsdbus-c++-doc

# dependencies for debian packaging
sudo apt install debhelper devscripts
# build .deb packages (will be placed into parent directory)
debuild --no-sign -b
# install built packages (and missing dependencies)
sudo debi --with-depends

Example code with be installed into /usr/share/libezcellular/examples/

• See meson_options.txt for options

# build everything
meson setup build --libdir=lib -Ddocs=true -Dexamples=true
# install (replace "install" with "uninstall" to remove everything)
sudo ninja -C build install

Options (from most to least recommended):

• Use pkgconfig of installed version to automatically add the needed include and linking flags
  • [RECOMMENDED] meson: https://mesonbuild.com/Dependencies.html
  • cmake: https://cmake.org/cmake/help/latest/module/FindPkgConfig.html
  • manually: g++ $(pkg-config --cflags ezcellular) example.cpp -o example $(pkg-config --libs ezcellular)
• Add CXX flags manually (good luck 😄)
• Build this library manually (maybe as meson subproject) and link it statically
  • https://mesonbuild.com/Dependencies.html#building-dependencies-as-subprojects

An example Meson project definition meson.build.example is part of the example files. Just rename it to meson.build and adjust contents as needed.

The code documentation is automatically built using doxygen, if enabled in the build configuration (-Ddocs=true). If you have installed the Debian package, you will find it here: file:///usr/share/doc/ezcellular/html/index.html.
