clang¶. Detect the Clang C compiler. waflib.Tools.clang.find_clang (conf) [source] ¶ Configuration Method bound to waflib.Configure.ConfigurationContext. Finds the program clang and executes it to ensure it really is clang

To use Clang you have two options: define the environment variables CC and CXX use the flags --check-c-compiler=clang and --check-cxx-compiler=clang++ in the configure stage of Waf The flags take priority over the env vars.

Doing it that way means we are replacing the compiler_c/cxx tools and in that case, and since we are using our own waf module, what should be done is to directly integrate toolchain support in each tool. I think the way it is done now is the best: it defaults to GCC if no flag is passed, just like now.

This is the v2 version of the PR #3722 Changes from that version are: rebased on master toolchain and compiler tools are now loaded by boards and before configuring the environment (this allows detection for compiler flags to be done in a standard way) fixed bug in boards configure toolchain is now a class attribute instead of define in the environment CC/CXX environment variables can't be ...

For best IDE support in Visual Studio, we recommend using the latest Clang compiler tools for Windows. If you don't already have those, you can install them by opening the Visual Studio Installer and choosing C++ Clang tools for Windows under Desktop development with C++ optional components.

C/C++ support¶ The following modules contain the functions and classes required for building C and C++ applications. They are almost always loaded by other Waf tools. Among these, the most important from a user point of view is waflib.Tools.c_config which provides the waflib.Tools.c_config.check() and waflib.Tools.c_config.check_cfg() functions.

Xcode ships Clang/LLVM besides GCC, so you could use Clang/LLVM instead. That -std=c++0x option is recognised by Clang/LLVM but C++0x is not as fully supported as in recent versions of GCC. The LLVM project keeps a page listing their current C++0x support status. Use a …

Not all compilers need to have a specific tool. For example, the clang compilers can be detected by the gcc tools when using:

Clang has experimental support for some proposed features of the C++ standard following C++17, provisionally named C++2a. Note that support for these features may change or be removed without notice, as the draft C++2a standard evolves.
