mongo-c-driver is a client library written in C for MongoDB.

There are absolutely no guarantees of API/ABI stability at this point. But generally, we won't break API/ABI unless we have good reason.

mongo-c-driver depends on Libbson.

If you are looking for the legacy C driver, it can be found in the legacy branch.

For issues with, questions about, or feedback for libmongoc, please look into our support channels. Please do not email any of the libmongoc developers directly with issues or questions - you're more likely to get an answer on the mongodb-user list on Google Groups.

Think you’ve found a bug? Want to see a new feature in libmongoc? Please open a case in our issue management tool, JIRA:

• Create an account and login.
• Navigate to the CDRIVER project.
• Click Create Issue - Please provide as much information as possible about the issue type and how to reproduce it.

Bug reports in JIRA for all driver projects (i.e. CDRIVER, CSHARP, JAVA) and the Core Server (i.e. SERVER) project are public.

If you’ve identified a security vulnerability in a driver or any other MongoDB project, please report it according to the instructions here.

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.

Fedora:

$ sudo yum install git gcc automake autoconf libtool

Debian:

$ sudo apt-get install git gcc automake autoconf libtool

FreeBSD:

$ su -c 'pkg install git gcc automake autoconf libtool'

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.

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
