Installation

1. To start integrating Ditto into your app you need to download a copy of the libditto.a static library and the Ditto.h header. The following command will download and then unpack an archive containing the library and header.

Select a tabLinux x86_64Linux aarch64iOS

For linux systems running on Intel-based CPUs with x86_64 architecture.

curl -O https://software.ditto.live/cpp-linux-x86_64/Ditto/4.7.0/dist/Ditto.tar.gz && tar xvfz Ditto.tar.gz

For linux systems running on ARM64-based CPUs with aarch64 architecture.

curl -O https://software.ditto.live/cpp-linux-aarch64/Ditto/4.7.0/dist/Ditto.tar.gz && tar xvfz Ditto.tar.gz

This iOS static library is "fat", containing slices for the following CPU archtectures: x86_64, arm64

curl -O https://software.ditto.live/cpp-ios/Ditto/4.7.0/dist/Ditto.tar.gz && tar xvfz Ditto.tar.gz

2. Configure your app to link to the Ditto static library. Usually, this will mean adding an -lditto to a compilation step for your app.

• Assume we have unzipped the Ditto.tar.gz in a relative directory ./sdk/
• main code entry point is in ./src/main.cpp
• output will be in ./dist/main

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

To add Bluetooth Low Energy capabilities please follow the instructions here.

• Assume we have unzipped the Ditto.tar.gz in a relative directory ./sdk/
• main code entry point is in ./src/main.cpp
• output will be in ./dist/main
• Notice we've added a -framework Security,CoreFoundation,CoreBluetooth,ObjC, this will enable the C++ SDK to leverage iOS peer to peer networks.

g++ -std=c++17 ./src/main.cpp -I ./sdk -lditto -ldl -framework Security,CoreFoundation,CoreBluetooth,ObjC -pthread -L ./sdk -o dist/main;

warning

Coming soon.

C++ is not currently supported on Windows.

3. Now, in your C++ code, you can import ditto with: #include <Ditto.h>

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