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 :py:attr:`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']
|
|
|

|
|
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
