If your configuration fits neither of these Look both for system installations of libstdc++ as well as installationsĪdjacent to Clang itself. The best version of libstdc++ headers available and use them - it will To find your C++ standard library headers.

If you intend to use Clang's C++ support, you may need to tell it how.

CMake allows you to generate project files for several IDEs: Xcode,Įclipse CDT4, CodeBlocks, Qt-Creator (use the CodeBlocks generator),.

Note: For subsequent Clang development, you can just run.

cmake -DLLVM_ENABLE_PROJECTS=clang -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles".

You need a debug build, switch Release to Debug.

This builds both LLVM and Clang in release mode.

mkdir build (in-tree build is not supported).

But if someone later becomes a contributor, since they can't push code from a shallow clone, it needs to be converted into a full clone:

For normal users looking to just compile, this command works fine.

git clone -depth=1 (using this only the latest version of llvm can be built).

Shallow clone saves storage and speeds up the checkout time. It can be made faster by creating a shallow clone.

Change directory to where you want the llvm directory placed.Note also that Python is needed for running the test suite.Getting Started with the LLVM System - Requirements. If you would like to check out and build Clang, the current procedure is as Building Clang and Working with the Code On Unix-like Systems From Xcode 4.2, Clang is the default compiler for Mac OS X. Ĭlang is also provided in all major BSD or GNU/Linux distributions as part of their respective packaging systems. You can download the release versions from.
