[isabelle-dev] mkdir failures

[Jasmin Blanchette]

Hi all,

Last week I experienced strange errors on my machine regarding "mkdir" on my Mac (with Nitpick and Sledgehammer), but these eventually went away after I pulled a newer version of Isabelle.

Now I'm testing on macbroy2 and getting similar errors, but this time in Imperative HOL:

*** Theory loader: failed to load "Imperative_HOL_ex" (unresolved "Linked_Lists", "Imperative_Reverse", "Imperative_Quicksort")
*** System command failed: mkdir -p '/tmp/isabelle-blanchet45778/Code_Test1375420'
*** At command "export_code" (line 1018 of "/Users/blanchet/rsync_isabelle/src/HOL/Imperative_HOL/ex/Linked_Lists.thy")

Has anybody run into similar issues before?

Thanks,

Jasmin
