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.

The documentation is available at http://api.mongodb.org/c/current/. 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 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, 1.2.1 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 ./autogen.sh or ./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-1.2.1.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.

Detailed installation instructions are in the manual: http://api.mongodb.org/c/current/installing.html

Download the latest release from the release page, then:

$ tar xzf mongo-c-driver-$ver.tar.gz
$ cd mongo-c-driver-$ver
$ ./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 2015, do the following:

cd mongo-c-driver-$ver
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\usr -G "Visual Studio 14 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 14 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj

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
$ git checkout x.y.z  # To build a particular release
$ ./autogen.sh --with-libbson=bundled
$ make
$ sudo make install

Building from Git on using Visual Studio 2015:

git clone https://github.com/mongodb/mongo-c-driver.git
cd mongo-c-driver
git checkout x.y.z # for your specific release
git submodule init
git submodule update # libbson is a submodule
cd src\libbson
cmake -DCMAKE_INSTALL_PREFIX=C:\libmongoc -G "Visual Studio 14 Win64" .
msbuild.exe ALL_BUILD.vcxproj
msbuild.exe INSTALL.vcxproj
cd ..\..
