mongo-c-driver is a client library written in C for MongoDB.
mongo-c-driver depends on Libbson. Libbson will automatically be built if you do not have it installed on your system.
If you are looking for the legacy C driver, it can be found in the legacy branch.

How To Ask For Help
If you are having difficulty building the driver after reading the below instructions, please email the mongodb-user list to ask for help. Please include in your email all of the following information:
- The version of the driver you are trying to build (branch or tag).
- Examples: master branch, 1.1.10 tag
- Host OS, version, and architecture.
- Examples: Windows 8 64-bit x86, Ubuntu 12.04 32-bit x86, OS X Mavericks
- C Compiler and version.
- Examples: GCC 4.8.2, MSVC 2013 Express, clang 3.4, XCode 5
The output of
./configure(depending on whether you are building from a repository checkout or from a tarball). The output starting from "libbson was configured with the following options" is sufficient.
The text of the error you encountered.
Failure to include the relevant information will result in additional round-trip communications to ascertain the necessary details, delaying a useful response. Here is a made-up example of a help request that provides the relevant information:
Hello, I'm trying to build the C driver with SSL, from mongo-c-driver-1.1.10.tar.gz. I'm on Ubuntu 14.04, 64-bit Intel, with gcc 4.8.2. I run configure like:$ ./configure --enable-sasl=yes checking for gcc... gcc checking whether the C compiler works... yes ... SNIPPED OUTPUT, but when you ask for help, include full output without any omissions ... checking for pkg-config... no checking for SASL... no checking for sasl_client_init in -lsasl2... no checking for sasl_client_init in -lsasl... no configure: error: You must install the Cyrus SASL libraries and development headers to enable SASL support.
Can you tell me what I need to install? Thanks!
If you’ve identified a security vulnerability in a driver or any other MongoDB project, please report it according to the instructions here.
Building from Release Tarball
Unless you intend on contributing to the mongo-c-driver, you will want to build from a release tarball.
The most current release is 1.1.10 which you can download here. mongo-c-driver-1.1.10.tar.gz.
To build on UNIX-like systems, do the following:
$ tar xzf mongo-c-driver-1.1.10.tar.gz $ cd mongo-c-driver-1.1.10 $ ./configure $ make $ sudo make install
To see all of the options available to you during configuration, run:
$ ./configure --help
To build on Windows Vista or newer with Visual Studio 2010, do the following:
cd mongo-c-driver-1.1.10 cd src\libbson cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" . msbuild.exe ALL_BUILD.vcxproj msbuild.exe INSTALL.vcxproj cd ..\.. cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" . msbuild.exe ALL_BUILD.vcxproj msbuild.exe INSTALL.vcxproj
Building From Git
mongo-c-driver contains a copy of libbson in the case that your system does not already have libbson installed. The configure script will detect if libbson is not installed and install it too.
$ sudo yum install git gcc automake autoconf libtool
$ sudo apt-get install git gcc automake autoconf libtool
$ su -c 'pkg install git gcc automake autoconf libtool'
Fetch Sources and Build
You can use the following to checkout and build mongo-c-driver:
git clone https://github.com/mongodb/mongo-c-driver.git cd mongo-c-driver ./autogen.sh make sudo make install
In standard automake fasion, ./autogen.sh only needs to be run once. You can use ./configure directly going forward. Also, see ./configure --help for all configure options.
Building on Windows
Currently, the cmake build system for mongo-c-driver does not build the libbson package as well. This needs to be done manually with cmake.
SSL is supported through the use of OpenSSL. SASL is not currently supported but is planned. To enable OpenSSL support, install the appropriate OpenSSL for Windows from here. The instructions below assume 64-bit builds, so you would want to get the version for "Win64 OpenSSL 1.0.1f" which includes libraries and headers.
If you are building from git, and not a release tarball, you also need to initialize the git submodule for libbson:
git submodule init git submodule update
Then proceed to build and install libbson using cmake and Visual Studio's command line tool, msbuild.exe. You can of course open these project files from Visual Studio as well:
cd src\libbson cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 10 Win64" . msbuild.exe ALL_BUILD.vcxproj msbuild.exe INSTALL.vcxproj cd ..\.. cmake -DCMAKE_INSTALL_PREFIX=C:\usr -DBSON_ROOT_DIR=C:\usr -G "Visual Studio 10 Win64" . msbuild.exe ALL_BUILD.vcxproj msbuild.exe INSTALL.vcxproj
Generating the Docs
To generate the documentation you must install the
On Linux this package can be found in the package manager for your distribution,
on OSX we recommend using TingPing's homebrew-gnome tap.
Then use the following
--enable-html-docs- builds the HTML documentation
--enable-man-pages- builds and installs the man-pages.
