At this point, Clang C++ is not production-quality and is not recommended for use beyond experimentation. However, Clang C++ support is under active development and is progressing rapidly. Please see the C++ Status page for details or ask on the mailing list about how you can help.

Note that released Clang compilers will refuse to even try to use clang to compile C++ code unless you pass the -ccc-clang-cxx option to the driver. To turn on Clang's C++ support, please pass that flag. Clang compilers built from the Subversion trunk enable C++ support by default, and do not require the -ccc-clang-cxx flag.

    -This page tracks the status of C++ support in Clang.
    -Clang implements the majority of C++ features, although there are many bugs remaining and Clang is not yet generally useful as a C++ compiler. If you are looking to get involved with Clang development to help work on support for C++, please also look at our Open Projects page and the LLVM bug tracker for some specific ideas.

    Clang C++ Status

    + + + +

    Clang currently implements nearly all of the ISO C++ 1998 standard +(including the defects addressed in the ISO C++ 2003 standard), with +the few notable exceptions listed below. However, the implementation +of Clang C++ is still quite immature, with many remaining bugs that +are likely to cause compiler crashes, erroneous errors and warnings, +and miscompiled code. The LLVM bug +tracker contains a Clang C++ component that tracks known Clang C++ +bugs.

    + +

    Clang is currently missing implementations of the following C++98/03 features and common extensions:

    Projects Building with Clang

    + +

    Clang is now capable of compiling some language C++ projects, or +large pieces of such projects. The following table describes various +projects that we have attempted to compile with Clang along with the results of that attempt.

    + +

    At this point in time, each new C++ project typically uncovers +new bugs. We keep track of these in the LLVM bug tracker via tracking bugs, +which are used to relate all of the bugs known to affect that +particular project. Introducing a new project in this list typically requires a liason familiar with LLVM or Clang development, who is able to provide detailed bug reports and track progress for the particular project.

    Implementation Status by Section

    Clang is still under heavy development. Clang is considered to be - a production quality C and Objective-C compiler when targetting X86-32 and X86-64 - (other targets may have caveats, but are usually easy to fix). If you are - looking for source - analysis or source-to-source transformation tools, clang is probably - a great solution for you. If you are interested in C++, - full support is still way off.
