## Project Status

| Signal  | Status                  | Project                                                                  |
| ------- | ----------------------- | ------------------------------------------------------------------------ |
| Traces  | Public Release          | N/A                                                                      |
| Metrics | Public Release          | N/A                                                                      |
| Logs    | Experimental [1]        | [Release Milestone](https://github.com/open-telemetry/opentelemetry-cpp/milestone/18)|

* [1]: The current Log Signal Implementation is Experimental, and will change as
      the current OpenTelemetry Log specification matures. The current
      implementation can be included in build by setting `ENABLE_LOGS_PREVIEW`
      preprocessor macro.

## Supported C++ Versions

Code shipped from this repository generally supports the following versions of
C++ standards:

* ISO/IEC 14882:2011 (C++11, C++0x)
* ISO/IEC 14882:2014 (C++14, C++1y)
* ISO/IEC 14882:2017 (C++17, C++1z)
* ISO/IEC 14882:2020 (C++20)

Any exceptions to this are noted in the individual `README.md` files.

Please note that supporting the [C Programming
Language](https://en.wikipedia.org/wiki/C_(programming_language)) is not a goal
of the current project.

## Supported Development Platforms

 Our CI pipeline builds and tests on following `x86-64` platforms:

| Platform                                                            |   Build type  |
|---------------------------------------------------------------------|---------------|
| ubuntu-22.04 (GCC - 10, 12)                                         | CMake, Bazel  |
| ubuntu-20.04 (GCC 4.8 with -std=c++11 flag)                         | CMake [1]     |
| ubuntu-20.04 (GCC 9.4.0)                                            | CMake, Bazel  |
| ubuntu-20.04 (Default GCC Compiler - 9.4.0 with -std=c++20 flags)   | CMake, Bazel  |
| macOS 12.0 (Xcode 14.2)                                             | Bazel         |
| Windows Server 2019 (Visual Studio Enterprise 2019)                 | CMake, Bazel  |
| Windows Server 2022 (Visual Studio Enterprise 2022)                 | CMake         |

[1]: Bazel build is disabled for GCC 4.8, as gRPC library 1.38 and above
  (required by OTLP exporter) don't build with this compiler. See gRPC [official
  support](https://grpc.io/docs/#official-support) document. CMake build doesn't
  build OTLP exporter with GCC 4.8.

In general, the code shipped from this repository should build on all platforms
having C++ compiler with [supported C++ standards](#supported-c-versions).

## Dependencies

Please refer to [Dependencies.md](docs/dependencies.md) for OSS Dependencies and
license requirements.

## Installation

Please refer to [INSTALL.md](./INSTALL.md).

## Getting Started

As an application owner or the library author, you can find the getting started
guide and reference documentation on
[opentelemetry-cpp.readthedocs.io](https://opentelemetry-cpp.readthedocs.io/en/latest/)

The `examples/simple` directory contains a minimal program demonstrating how to
instrument a small library using a simple `processor` and console `exporter`,
along with build files for CMake and Bazel.
