LLVM Clang-CL support.
|
|
|
|
Clang-CL is supposed to be a drop-in replacement for MSVC CL, but also serves
|
|
well as a cross compiler for Windows from Linux (provided you have set up the
|
|
environment). Requires Visual Studio 2015+ to be installed.
|
|
|
|
On Windows it uses (most) MSVC tools.
|
|
|
|
Usage:
|
|
$ waf configure
|
|
Or:
|
|
$ LLVM_PATH=C:\\Program Files\\LLVM\\bin waf configure
|
|
Or:
|
|
def configure(conf):
|
|
conf.env.LLVM_PATH = 'C:\\Program Files\\LLVM\\bin'
|
|
conf.load('clang_cl')
