Opened an ECL bug here:
Why does it fail?
Sorry, that's all info I have for now. I hope maybe Juan Jose will be able to quickly understand it.
If I have more info I will report here.
Tracked it down to the functino find-valid-system-index in the file local-projects.lisp.
It tries to do
(when (and probed
(<= (directory-write-date pathname)
without taking into account that directory-write-date may return nil (as it is implemented using file-write-date).
BTW, the directory it tests, C:/Users/anton/quicklisp/local-projects/, exists.
Thanks. I'll try to find out how to get the directory-write-date in ECL for Windows.
According to Juanjo this is a bug in file-write-date in Windows ECL. It should be fixed very soon.
file-write-date is allowed to return NIL by CLHS, so probably quicklisp code should handle this situation somehow.
