Getting Started: Building and Running Clang This page gives you the shortest path to checking out Clang and demos a few options. Building Clang and Working with the Code On Unix-like Systems If you would like to check out and build Clang, the current procedure is as follows: Get the required tools.

Note also that Python is needed for running the test suite. It can be made faster by creating a shallow clone. Shallow clone saves storage and speeds up the checkout time.

Note: For subsequent Clang development, you can just run make clang. Source code control program. This is used for generating Visual Studio solution and project files. It is used to run the clang test suite. The gnuwin32 packages are the oldest and most well-tested way to get these tools. However, the MSys utilities provided by git for Windows have been known to work. Cygwin has worked in the past, but is not well tested. To generate x86 binaries instead of x64, pass -A Win The above, if successful, will have created an LLVM.

See the running examples from above. Using Ninja alongside Visual Studio We recommend that developers who want the fastest incremental builds use the Ninja build system. You can use the generated Visual Studio project files to edit Clang source code and generate a second build directory next to it for running the tests with these steps: Check out clang and LLVM as described above Open a developer command prompt with the appropriate environment.

If you open the start menu and search for "Command Prompt", you should see shortcuts created by Visual Studio to do this. Alternatively, launch a regular cmd prompt and run the appropriate vcvarsall. All of these were motivations for starting work on a new front-end that could meet these needs.

As example, Clang is used in production to build performance-critical software like Chrome or Firefox. If you are looking for source analysis or source-to-source transformation tools, Clang is probably a great solution for you. Start by getting the code, building it, and playing with it.

This will show you the sorts of things we can do today and will let you have the "Clang experience" first hand: hopefully it will "resonate" with you.

Once you've done that, please consider getting involved in the Clang community. The Clang developers include numerous volunteer contributors with a variety of backgrounds.
