it seems a consequence of cygwin 2.5.2
Commit 8a31aa3 introduces the problem. 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...
Corinna
I 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
