我们从Python开源项目中，提取了以下9个代码示例，用于说明如何使用distutils.sysconfig.get_makefile_filename()。
def test_srcdir(self): # See Issues #15322, #15364. srcdir = sysconfig.get_config_var('srcdir') self.assertTrue(os.path.isabs(srcdir), srcdir) self.assertTrue(os.path.isdir(srcdir), srcdir) if sysconfig.python_build: # The python executable has not been installed so srcdir # should be a full source checkout. Python_h = os.path.join(srcdir, 'Include', 'Python.h') self.assertTrue(os.path.exists(Python_h), Python_h) self.assertTrue(sysconfig._is_python_source_dir(srcdir)) elif os.name == 'posix': self.assertEqual( os.path.dirname(sysconfig.get_makefile_filename()), srcdir)
