[New-bugs-announce] [issue20705] distutils.extension.Extension with empty 'sources' list
report at bugs.python.org
Thu Feb 20 20:08:14 CET 2014
New submission from Rémi Rampin:
While this is obviously a programming error, distutils currently has no check for the 'sources' list being empty, which might or might not result in a self-explanatory error message once the CCompiler's link() method is called (the exact error depends on the subclass's implementation).
It seems that some code had been put in initially to handle this case ('objects or ' constructs) but this has been broken since (objects used by most subclasses).
Since objects can only be empty if sources was empty, I think catching this case in build_extension() (only caller of link_shared_object) makes sense.
Trivial patch attached, should apply on all versions.
