# C / C++ Monitoring Supported Versions

## Overview{% #overview %}

The Datadog C++ SDK supports native C and C++ applications on Linux, macOS, and Windows. SDK builds are tested on a range of compiler toolchains and 64-bit CPU architectures.

The SDK is built with CMake and officially integrates with CMake 3.21 or later. Applications using other build systems can link against precompiled SDK binaries directly.

## Compiler support{% #compiler-support %}

Builds of the C++ SDK are officially tested on these operating systems, compilers, and architectures:

| Platform | Compiler toolchain                 | Built on                     |
| -------- | ---------------------------------- | ---------------------------- |
| Linux    | GCC 11, GCC 13, Clang 15, Clang 20 | Ubuntu 22.04 (x86_64)        |
| macOS    | AppleClang 15 (Xcode 15.3)         | macOS 14 Sonoma (arm64)      |
| Windows  | MSVC 2022 (v17.14, toolset v143)   | Windows Server 2022 (x86_64) |

Other compilers with C++17 support are expected to work but are not officially validated in CI.

The C API is compatible with C99 and can be used by applications without C++ language support.

## Dependencies{% #dependencies %}

For a full list of third-party components, see [`LICENSE-3rdparty.csv`](https://github.com/DataDog/dd-sdk-cpp/blob/main/LICENSE-3rdparty.csv) in the SDK repository.

### libcurl{% #libcurl %}

The SDK uses libcurl for HTTP transport. On Linux and macOS, the SDK links against the system-provided libcurl by default. You can override this to bundle a static libcurl build by setting the CMake option `DD_HTTP_USE_SYSTEM_LIBCURL=OFF`. On Windows, libcurl is always built from source as part of the SDK build.
