zenoh-cpp-example

The repo shows how to build zenoh-cpp program with zenoh-c or zenoh-pico.

Build

You have two options for providing the necessary Zenoh dependencies:

Option 1: Install packages via APT (Ubuntu)

If you are on Ubuntu, you can install the pre-built libraries directly:

sudo apt update
sudo apt install libzenohcpp-dev libzenohc-dev libzenohpico-dev

Once installed, you can simply build the examples:

just examples

Option 2: Build dependencies from source using justfile

• Get submodule

just prepare

• Build all the dependencies

just lib

Once built, you can simply build the examples:

just examples

Usage

• Using zenoh-c

# Run router
./build/zenoh_router "[\"tcp/localhost:8888\"]"
# Run subscriber
./build/zenoh_subscriber "[\"tcp/localhost:8888\"]"
# Run get
./build/zenoh_get "[\"tcp/localhost:8888\"]"
# Run put
./build/zenoh_put "[\"tcp/localhost:8888\"]"
# Router loads REST plugin by default. You can curl the information
curl http://localhost:8000/**

• Using zenoh-cpp

# Run router
./build/zenoh_router
# Run put
## with zenoh-c backened
./build/zenoh_put_cpp_zc
## with zenoh-pico backend
./build/zenoh_put_cpp_zpico

Note

To use plugins in router mode, note that:

• The plugins and zenoh-c should be consistent, including Zenoh version and build features.
• The feature plugins should be enabled while building zenoh-c.
• The feature shared-memory should be enabled while building plugins, since zenoh-c needs this.
