mongo-c-driver is a project that includes two libraries:

• libmongoc, a client library written in C for MongoDB.
• libbson, a library providing useful routines related to building, parsing, and iterating BSON documents.

If libmongoc is not needed, it is possible to build and install only libbson.

This project usesSemantic Versioning.

The documentation is available atMongoDB C Driver Docs andhttps://www.mongoc.org.For issues with, questions about, or feedback for libmongoc, please look intooursupport channels. Pleasedo not email any of the libmongoc developers directly with issues orquestions - you're more likely to get an answer on theMongoDB Community Forums orStackOverflow.

• Navigate tothe CDRIVER project.
• ClickCreate 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 theCore Server (i.e. SERVER) project arepublic.

If you are having difficulty building the driver after reading the below instructions, please post ontheMongoDB Community Forums to ask for help. Please include in your post all of the followinginformation:

• The version of the driver you are trying to build (branch or tag).

  • Examples:r1.17 (branch),1.9.5 (tag)

• Host OS, version, and architecture.

  • Examples: Windows 10 64-bit x86, Ubuntu 16.04 64-bit x86, macOS 11.0

• C Compiler and version.

  • Examples: GCC 7.3.0, Visual Studio Community 2017, clang 3.9, XCode 9.3

• Run CMake with--log-level=debug and--log-context for more verbose output.
• The output of anycmake,make, or other commands executed during the build.
• The text of the error you encountered.

Failure to include the relevant information will delay a useful response.Here is a made-up example of a help request that provides the relevantinformation:

Hello, I'm trying to build the C driver with Kerberos support, frommongo-c-driver-1.9.5.tar.gz. I'm on Ubuntu 16.04, 64-bit Intel, with gcc5.4.0. I run CMake like:

$ cmake .-- The C compiler identification is ;GNU 5.4.0-- Check for working C compiler: /usr/bin/cc-- Check for working C compiler: /usr/bin/cc -- works... SNIPPED OUTPUT, but when you ask for help, include full output without any omissions ...-- Searching for libsasl2--   Not found (specify -DCMAKE_LIBRARY_PATH=/path/to/sasl/lib for SASL support)CMake Error at CMakeLists.txt:10 (_message):    SASL not found

Can you tell me what I need to install? Thanks!
