compiler_c

Try to detect a C compiler from the list of supported compilers (gcc, msvc, etc):

def options(opt):
        opt.load('compiler_c')
def configure(cnf):
        cnf.load('compiler_c')
def build(bld):
        bld.program(source='main.c', target='app')

The compilers are associated to platforms in waflib.Tools.compiler_c.c_compiler. To register a new C compiler named cfoo (assuming the tool waflib/extras/cfoo.py exists), use:

from waflib.Tools.compiler_c import c_compiler
c_compiler['win32'] = ['cfoo', 'msvc', 'gcc']

def options(opt):
        opt.load('compiler_c')
def configure(cnf):
        cnf.load('compiler_c')
def build(bld):
        bld.program(source='main.c', target='app')

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

$ CC=clang waf configure
waflib.Tools.compiler_c.c_compiler = {'aix': ['xlc', 'gcc', 'clang'], 'cygwin': ['gcc'], 'darwin': ['clang', 'gcc'], 'default': ['clang', 'gcc'], 'gnu': ['gcc', 'clang'], 'hpux': ['gcc'], 'irix': ['gcc', 'irixcc'], 'java': ['gcc', 'msvc', 'clang', 'icc'], 'linux': ['gcc', 'clang', 'icc'], 'osf1V': ['gcc'], 'sunos': ['suncc', 'gcc'], 'win32': ['msvc', 'gcc', 'clang']}

Dict mapping platform names to Waf tools finding specific C compilers:

from waflib.Tools.compiler_c import c_compiler
c_compiler['linux'] = ['gcc', 'icc', 'suncc']
waflib.Tools.compiler_c.configure(conf)[source]

Detects a suitable C compiler

Raises:waflib.Errors.ConfigurationError when no suitable compiler is found
waflib.Tools.compiler_c.debug(*k, **kw)[source]

Wraps logging.debug and discards messages if the verbosity level waflib.Logs.verbose ≤ 0

waflib.Tools.compiler_c.options(opt)[source]

This is how to provide compiler preferences on the command-line:

$ waf configure --check-c-compiler=gcc
