1.5.12: problems without registry keys

Tue Dec 7 17:12:00 GMT 2004

 I have a custom app. (linux or windows) I've been
compiling with cygwin for about 6 months. It use to
run fine on any computer as long as there was a copy
of "cygwin1.dll" along with the exe.
 Now (ver 1.5.12) the app just hangs on any computer
that doesn't have cygwin installed. After a lot of
hair pulling, I think I've discovered the issue. In
the registry, there are a set of keys for the cygwin's
mount points. For some applications (such as mine), I
fount you will need these registry keys or the app
will simply hang.
 My application is a bit complicated to explain, but
usually froze at some point trying to open a file
stream. But some other apps I compiled didn't have
this issue. The app uses pthreads and semaphores (the
functioning app did not). I could answerer any
questions or possibility write some code to reproduce
this problem if it would help.
 Even if they registry keys don't point to anything
valid, the application still runs. Says to me,
cygwin1.dll just needs the keys to exist.
 I have a working solution, but I thought I'd post
this in case someone else is banging their head on a
desk somewhere.
