The patch disallows to dlopen libs without specifying the file extension. This was originally intended by commit df958670 but only worked for paths, not simple filenames. AFAICS this is a more a ruby problem than a Cygwin problem. It tries to dlopen a DLL called "kernel32". But dlopen is POSIX, so it should not assume that an extension is added automatically, just as this isn't done on Linux. Hmm, I'm undecided if this should be fixed in ruby or if we need a Cygwin 2.5.3 reverting this patch... CorinnaI ran into this too on Saturday night- I ended up opening the Fiddle file in question and putting the full path (including the extension) to fix the issue. Wish I would have tried with just the extension The weird thing is- after upgrading, I tried reverting ruby and ruby-gems to older versions but had no luck. Corinna, where did a change occur that caused this to happen? You mention dlopen, which package is this a part of? Thanks Brian
revert cygwin from 2.5.2 to 2.5.1, dlopen is a system call provided by cygwin1.dll -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
