Check for the availability of a typedef
by using the CheckType
method:
env = Environment() conf = Configure(env) if not conf.CheckType('off_t'): print('Did not find off_t typedef, assuming int') conf.env.Append(CPPDEFINES=('off_t','int')) env = conf.Finish()
You can also add a string that will be
placed at the beginning of the test file
that will be used to check for the typedef
.
This provide a way to specify
files that must be included to find the typedef
:
env = Environment() conf = Configure(env) if not conf.CheckType('off_t', '#include <sys/types.h>\n'): print('Did not find off_t typedef, assuming int') conf.env.Append(CPPDEFINES=('off_t','int')) env = conf.Finish()
