Returns a tuple (status, details), where 'status' is one of the following constants: - CONFIG_H_OK: all is well, go ahead and compile - CONFIG_H_NOTOK: doesn't look good - CONFIG_H_UNCERTAIN: not sure -- unable to read pyconfig.h 'details' is a human-readable string explaining the situation. Note there are two ways to conclude "OK": either 'sys.version' contains the string "GCC" (implying that this Python was built with GCC), or the installed "pyconfig.h" contains the string "__GNUC__". r )� sysconfigZGCCzsys.version mentions 'GCC'Z__GNUC__z'%s' mentions '__GNUC__'z '%s' does not mention '__GNUC__'Nzcouldn't read '%s': %s) � distutilsrV r r r& �get_config_h_filename�open�read�CONFIG_H_NOTOK�close�OSError�CONFIG_H_UNCERTAIN�strerror)rV �fn�config_h�excr r r r% H s r% s (\d+\.\d+(\.\d+)*)c C sl | j � d }t|�dkr dS t| dtd�j}z |j� }W d|j� X tj|�}|dkrZdS t |j d�j � �S )z�Find the version of an executable by running `cmd` in the shell.
