LDC – the LLVM-based D Compiler

Build Status Test Coverage Bountysource

The LDC project aims to provide a portable D programming language compiler with modern optimization and code generation capabilities.

The compiler uses the official DMD frontends to support the latest version of D2, and relies on the LLVM Core libraries for code generation.

LDC is fully Open Source; the parts of the code not taken/adapted from other projects are BSD-licensed (see the LICENSE file for details).

Please consult the D wiki for further information:

D1 is no longer available; see the 'd1' Git branch for the last version supporting it.


In-depth material on building and installing LDC and the standard libraries, including experimental instructions for running LDC on Windows, is available on the project wiki at

If you have a working C++ build environment, CMake, a current LLVM, and libconfig available there should be no big surprises, though.

Do not forget to make sure all the submodules are up to date:

$ cd ldc
$ git submodule update --init

Some Linux and OS X package managers include recent versions of LDC, so manually installing it might not be necessary. For several platforms, there are also stand-alone binary builds available at the GitHub release page.


The best way to get in touch with the developers is either via the digitalmars.D.ldc forum/newsgroup/mailing list ( or the #ldc IRC channel on FreeNode.
