LaunchDarkly Sample C++ Client-Side Application

We've built a simple console application that demonstrates how LaunchDarkly's SDK works. Below, you'll find the basic build procedure, but for more comprehensive instructions, you can visit your Quickstart page or the C/C++ SDK reference guide page. Use this as a starting point for integrating the c-client-sdk with your application.

Build instructions

1. Edit hello.cpp and set the value of MOBILE_KEY to your LaunchDarkly mobile key. If there is an existing boolean feature flag in your LaunchDarkly project that you want to evaluate, set FEATURE_KEY to the flag key.

#define MOBILE_KEY "YOUR_MOBILE_KEY"
#define FEATURE_KEY "YOUR_FEATURE_KEY"

2. Download the latest SDK for your platform with fetch-linux.sh, fetch-mac.command, or fetch-windows.ps1.
3. Build for your platform with build-linux.sh, build-mac.command, or build-windows.ps1.
4. On the command line, run ./hello.

You should receive the message "Feature flag '<flag key>' is <true/false> for this user".
