MongoDB C++ Driver Build Status

Welcome to the MongoDB C++ Driver!

Please see our wiki page for information about building, testing, and using the driver.

Version 1.0.2 of the C++ legacy driver has been released. Please report any bugs or issues in the C++ JIRA project.

Version 1.0.3-rc0 of the C++ legacy driver has been released for testing. Please report any bugs or issues in the C++ JIRA project.

Use the legacy branch if:

  • You are using MongoDB's C++ driver for the first time.
  • You had been using 26compat (or the driver inside of the server source) and want to benefit from incremental improvements while having the same overall API.

Use the 26compat branch only if:

  • You have existing code that used the driver from the 2.6 or earlier server source and want it to continue working without modification.

Note: As of MongoDB 2.6.0-rc1, it is no longer possible to build the driver from the server sources: this repository is the only approved source for C++ driver builds.

Repository Overview

Branch Stability Development Purpose
master Alpha In progress New C++11 driver
legacy Stable Stable Evolution Primary stable C++ driver release
26compat Stable Maintenance Only Drop in replacement for users of existing 2.6 era C++ driver

Please note that stable branches are only production quality at stable release tags. Other commits or pre-release tags on a stable branch represent ongoing development work towards the next stable release, and therefore may be unstable.

WARNING: The master branch contains development work on a new driver with a completely new API and implementation. It is a work in progress and currently should not be used.


  • libmongoclient.[so|dylib|dll] - The shared mongoclient library (but see notes)
  • libmongoclient.a - The static mongoclient library

Building and Usage

Bugs and Issues



Use of the shared library is experimental on windows and is currently discouraged. This is primarily due to the complexity of ensuring a matching implementation of STL types between library and consumer code. This problem is unique to windows, as the consistent use of system libraries largely mitigates this danger.
