INSTALL WITH A PACKAGE MANAGER

The libmongoc package is available on recent versions of Debian and Ubuntu.

        $ apt-get install libmongoc-1.0-0

On Fedora, a mongo-c-driver package is available in the default repositories and can be installed with:

        $ dnf install mongo-c-driver

On recent Red Hat systems, such as CentOS and RHEL 7, a mongo-c-driver package is available in the EPEL repository. To check version available, see https://apps.fedoraproject.org/packages/mongo-c-driver. The package can be installed with:

        $ yum install mongo-c-driver

BUILDING ON UNIX

  Prerequisites

OpenSSL is required for authentication or for SSL connections to MongoDB. Kerberos or LDAP support requires Cyrus SASL.

To install all optional dependencies on RedHat / Fedora:

        $ sudo yum install pkg-config openssl-devel cyrus-sasl-devel

On Debian / Ubuntu:

        $ sudo apt-get install pkg-config libssl-dev libsasl2-dev

On FreeBSD:

        $ su -c 'pkg install pkgconf openssl cyrus-sasl'

  Building from a release tarball

Unless you intend on contributing to the mongo-c-driver, you will want to build from a release tarball.

The most recent release of libmongoc is 1.9.2 and can be downloaded here. The following snippet will download and extract the driver, and configure it:

        $ wget https://github.com/mongodb/mongo-c-driver/releases/download/1.9.2/mongo-c-driver-1.9.2.tar.gz
        $ tar xzf mongo-c-driver-1.9.2.tar.gz
        $ cd mongo-c-driver-1.9.2
        $ ./configure --disable-automatic-init-and-cleanup

The --disable-automatic-init-and-cleanup option is recommended, see init-cleanup. For a list of all configure options, run ./configure --help.

If configure completed successfully, you'll see something like the following describing your build configuration.

        libmongoc 1.9.2 was configured with the following options:

        Build configuration:
          Enable debugging (slow)                          : no
          Compile with debug symbols (slow)                : no
          Enable GCC build optimization                    : yes
          Enable automatic init and cleanup                : no
          Enable maintainer flags                          : no
          Code coverage support                            : no
          Cross Compiling                                  : no
          Fast counters                                    : no
          Shared memory performance counters               : yes
          SASL                                             : sasl2
          SSL                                              : openssl
          Snappy Compression                               : no
          Zlib Compression                                 : bundled
          Libbson                                          : bundled

        Documentation:
          man                                              : no
          HTML                                             : no

mongo-c-driver contains a copy of libbson, in case your system does not already have libbson installed. The configure script will detect if libbson is not installed and use the bundled libbson.

        $ make
        $ sudo make install

  Building from git

To build an unreleased version of the driver from git requires additional dependencies.

RedHat / Fedora:

        $ sudo yum install git gcc automake autoconf libtool

Debian / Ubuntu:

        $ sudo apt-get install git gcc automake autoconf libtool

FreeBSD:

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

Once you have the dependencies installed, clone the repository and build the current master or a particular release tag:

        $ 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

  Generating the documentation

Install Sphinx, then:

        $ ./configure --enable-html-docs --enable-man-pages
        $ make man html

BUILDING ON MAC OS X

Install the XCode Command Line Tools:

        $ xcode-select --install

The pkg-config utility is also required. First install Homebrew according to its instructions, then:

        $ brew install pkgconfig

Download the latest release tarball:

        $ curl -LO https://github.com/mongodb/mongo-c-driver/releases/download/1.9.2/mongo-c-driver-1.9.2.tar.gz
        $ tar xzf mongo-c-driver-1.9.2.tar.gz
        $ cd mongo-c-driver-1.9.2

Build and install the driver:

        $ ./configure
        $ make
        $ sudo make install

  Native TLS Support on Mac OS X / Darwin (Secure Transport)

The MongoDB C Driver supports the Darwin native TLS and crypto libraries. Using the native libraries there is no need to install OpenSSL. By default however, the driver will compile against OpenSSL if it detects it being available. If OpenSSL is not available, it will fallback on the native libraries.

To compile against the Darwin native TLS and crypto libraries, even when OpenSSL is available, configure the driver like so:

        $ ./configure --enable-ssl=darwin

  OpenSSL support on El Capitan

Beginning in OS X 10.11 El Capitan, OS X no longer includes the OpenSSL headers. To build the driver with SSL on El Capitan and later:

        $ brew install openssl
        $ export LDFLAGS="-L/usr/local/opt/openssl/lib"
        $ export CPPFLAGS="-I/usr/local/opt/openssl/include"

BUILDING ON WINDOWS

Building on Windows requires Windows Vista or newer and Visual Studio 2010 or newer. Additionally, cmake is required to generate Visual Studio project files.

Let's start by generating Visual Studio project files for libbson, a dependency of the C driver. The following assumes we are compiling for 64-bit Windows using Visual Studio 2015 Express, which can be freely downloaded from Microsoft.

        cd mongo-c-driver-1.9.2\src\libbson
        cmake -G "Visual Studio 14 2015 Win64" \
          "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" \
          "-DCMAKE_BUILD_TYPE=Release" # Defaults to debug builds

(Run cmake -LH . for a list of other options.)

Now that we have project files generated, we can either open the project in Visual Studio or compile from the command line. Let's build using the command line program msbuild.exe

        msbuild.exe /p:Configuration=Release ALL_BUILD.vcxproj

Now that libbson is compiled, let's install it using msbuild. It will be installed to the path specified by CMAKE_INSTALL_PREFIX.

        msbuild.exe /p:Configuration=Release INSTALL.vcxproj

You should now see libbson installed in C:\mongo-c-driver

Now let's do the same for the MongoDB C driver.

        cd mongo-c-driver-1.9.2
        cmake -G "Visual Studio 14 2015 Win64" \
          "-DENABLE_SSL=WINDOWS" \
          "-DENABLE_SASL=SSPI" \
          "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver" \
          "-DCMAKE_PREFIX_PATH=C:\mongo-c-driver" \
          "-DCMAKE_BUILD_TYPE=Release" # Defaults to debug builds

        msbuild.exe /p:Configuration=Release ALL_BUILD.vcxproj
        msbuild.exe /p:Configuration=Release INSTALL.vcxproj

All of the MongoDB C Driver's components will now have been build in release mode and can be found in C:\mongo-c-driver. To build and install debug binaries, remove the "-DCMAKE_BUILD_TYPE=Release" argument to cmake and /p:Configuration=Release to msbuild.exe.

To use the driver libraries in your program, see visual-studio-guide.

  Native TLS Support on Windows (Secure Channel)

The MongoDB C Driver supports the Windows native TLS and crypto libraries. Using the native libraries there is no need to install OpenSSL. By default however, the driver will compile against OpenSSL if it detects it being available. If OpenSSL is not available, it will fallback on the native libraries.

To compile against the Windows native TLS and crypto libraries, even when OpenSSL is available, configure the driver like so:

        cmake -G "Visual Studio 14 2015 Win64" \
          "-DENABLE_SSL=WINDOWS" \
          "-DCMAKE_INSTALL_PREFIX=C:\\mongo-c-driver" \
          "-DCMAKE_PREFIX_PATH=C:\\mongo-c-driver"

  Native SASL Support on Windows (SSPI)

The MongoDB C Driver supports the Windows native Kerberos and Active Directory interface, SSPI. Using the native libraries there is no need to install any dependencies, such as cyrus-sasl. By default however, the driver will compile against cyrus-sasl.

To compile against the Windows native SSPI, configure the driver like so:

        cmake -G "Visual Studio 14 2015 Win64" \
          "-DENABLE_SASL=SSPI" \
          "-DCMAKE_INSTALL_PREFIX=C:\\mongo-c-driver" \
          "-DCMAKE_PREFIX_PATH=C:\\mongo-c-driver"

  OpenSSL support on Windows

For backwards compatibility CMake will default to OpenSSL support. If not found, it will fallback to native TLS support provided by the platform.

OpenSSL 1.1.0 support requires CMake 3.7 or later on Windows.
