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__'zcouldn't read '%s': %sN) Z distutilsrT r r r$ Zget_config_h_filename�open�read�close�CONFIG_H_NOTOK�OSError�CONFIG_H_UNCERTAIN�strerror)rT �fnZconfig_h�excr r r r# F s& � � �r# s (\d+\.\d+(\.\d+)*)c C st | � � d }t|�du r dS t| dtd�j}z|�� }W |�� n |�� 0 t�|�}|du rbdS t |� d�� � �S )z�Find the version of an executable by running `cmd` in the shell.
