Simple C++ example

Simple example receiving and sending MAVLink v2 over UDP based on POSIX APIs (e.g. Linux, BSD, macOS).

This is the C++11 counterpart to the C example. Instead of the C pack/decode functions it uses the generated message structs (e.g. mavlink::minimal::msg::HEARTBEAT) together with mavlink::MsgMap to serialize and deserialize to and from a mavlink_message_t.

Note The C++11 library requires the user to provide a mavlink::mavlink_get_msg_entry() function so that mavlink_parse_char() can look up the length and CRC extra of incoming messages. This example builds it from the dialect's MESSAGE_ENTRIES table (see the top of udp_example.cpp).

Install MAVLink

In top level directory, build and install the MAVLink headers locally into the install folder:

cmake -Bbuild -H. -DCMAKE_INSTALL_PREFIX=install
cmake --build build --target install

This installs both the C (*.h) and C++11 (*.hpp) headers.

Build example

In the example directory, build the example while passing the local install directory:

cd examples/cpp
cmake -Bbuild -H. -DCMAKE_PREFIX_PATH=$(pwd)/../../install
cmake --build build
