You can integrate the Ditto SDK into C++ projects to develop for Linux and iOS platforms.

For a complete overview of the platforms, transports, and devices the C# SDK supports, select **C++ **from the Directory of Compatibility Maps.

For the API reference, see Ditto 4.7.1 API Reference Documentation.

To install the C++ SDK:

1

Fetch and extract the Ditto package. (Downloading and Unpacking Ditto)

2

Configure your app to link to the Ditto static library. (Linking to Ditto)

​
Downloading and Unpacking Ditto

Download Ditto.tar.gz and unpack an archive containing the libditto.a static library and Ditto header:

curl -O https://software.ditto.live/cpp-linux-x86_64/Ditto/4.7.4/dist/Ditto.tar.gz && tar xvfz Ditto.tar.gz

​
Linking to Ditto

Add -lditto as a compilation step in the main.cpp source file:

For instructions on adding cross-platform Bluetooth Low Energy (LE) capabilities, see Bluetooth on Linux.

BlueZ is the official Bluetooth protocol stack implementation for Linux systems to communicate with other Bluetooth-enabled platforms.

# This command assumes:
# You have unzipped the Ditto.tar.gz in a relative directory ./sdk/
# Your main code entry point is in ./src/main.cpp

g++ -std=c++17 ./src/main.cpp -I ./sdk -lditto -ldl -lrt -pthread -L ./sdk -o dist/main;

 # Once executed, your output will be available at: ./dist/main

​
Importing Ditto

From the source code of your app, using #include <Ditto.h>, import Ditto and provide your access credentials:

C++
auto identity =
    Identity::OnlinePlayground("YOUR_APP_ID", "PLAYGROUND_TOKEN", true);
try {
  Ditto ditto = Ditto(identity, dir);
  ditto.set_minimum_log_level(LogLevel::debug);
  ditto.start_sync();
} catch (const DittoError &err) {
}
