Contributing

Before considering contributions to the project, please take a moment to read our brief contribution guidelines.

Build and Test (Linux and macOS)

Dependencies

Building this project requires the following tools installed:

Build tools (e.g. build-essential, xcode)
cmake >= 3.1

Additional libraries are installed via a script.

Build Steps

Clone the repository

git clone https://github.com/DataDog/dd-opentracing-cpp

Install additional library dependencies (requires sudo)

cd dd-opentracing-cpp
sudo scripts/install_dependencies.sh

Generate build files using cmake
```
mkdir .build
cd .build
cmake ..
```
Run the build
```
make
```

(Optional) Run the tests

cmake -DBUILD_TESTING=ON ..
make
ctest --output-on-failure

(Optional) Install to /usr/local
```
make install
```

If you want sanitizers to be enabled, then add either the -DSANITIZE_THREAD=ON -DSANITIZE_UNDEFINED=ON or -DSANITIZE_ADDRESS=ON flags to cmake, running the tests will now also check with the sanitizers.

You can enable code coverage instrumentation in the builds of the library and its unit tests by adding the -DBUILD_COVERAGE=ON flag to cmake. See scripts/run_coverage.sh.

Build (Windows)

NOTE: This is currently Early Access, and issues should be reported only via GitHub Issues. Installation steps are likely to change based on user feedback and becoming available via Vcpkg.

Dependencies

Building this project requires the following tools installed:

Visual Studio 2019 with "Desktop development for C++" installed
Vcpkg
Git

Build Steps

The commands below should be executed in an x64 Native Tools Command Prompt shell.

Clone the repository

cd %HOMEPATH%
git clone https://github.com/DataDog/dd-opentracing-cpp

Generate build files using cmake

cd dd-opentracing-cpp
mkdir .build
cd .build
cmake -DCMAKE_TOOLCHAIN_FILE=%HOMEPATH%\vcpkg\scripts\buildsystems\vcpkg.cmake ..

Run the build

cmake --build . -- -p:Configuration=RelWithDebInfo

Take care to update the Configuration value (e.g. to Debug) if you change the build mode in your IDE. See this related issue.

Integration tests

Integration tests require additional tools installed:

Installation details can be extracted from the Dockerfile for the container that is usually used when running integration tests.
