Function base_compiler

pipcl.py:1971–2018

Returns basic compiler command and PythonFlags. Args: vs: Windows only. A `wdev.WindowsVS` instance or None to use default `wdev.WindowsVS` instance. pythonflags: A `pipcl.PythonFlags` instance or None to use default `pipcl.Py

    Returns basic compiler command and PythonFlags.

    Args:
        vs:
            Windows only. A `wdev.WindowsVS` instance or None to use default
            `wdev.WindowsVS` instance.
        pythonflags:
            A `pipcl.PythonFlags` instance or None to use default
            `pipcl.PythonFlags` instance.
        cpp:
            If true we return C++ compiler command instead of C. On Windows
            this has no effect - we always return `cl.exe`.
        use_env:
            If true we return '$CC' or '$CXX' if the corresponding
            environmental variable is set (without evaluating with `getenv()`
            or `os.environ`).

    Returns `(cc, pythonflags)`:
        cc:
            C or C++ command. On Windows this is of the form
            `{vs.vcvars}&&{vs.cl}`; otherwise it is typically `cc` or `c++`.
        pythonflags:
            The `pythonflags` arg or a new `pipcl.PythonFlags` instance.
