Execute `cygcheck -s -v -r', at the end of the list you'll see where on the
path that every cygwin1.dll is found.  Somehow, you're starting processes with
differing versions of cygwin1.dll.  This is a big cannot do.  Chris added the
"conflicting versions" error to prevent more serious problems.  You need to get
rid of all but one of the cygwin1.dll files from your PATH.

I avoided suggesting running cygcheck because I thought it possible that
it wouldn't run either since it's a cygwin app.  But, if it does run
it may determine the problem.

Yes.  Only use one version of the DLL on your system.  That's what the
error message was trying to tell you.  Rename the older DLL to something
besides cygwin1.dll.

termios control in cygwin

[Svein Erling Seldal]

Hi,

I'm trying to access the serial/console port from a gcc/cygwin
program. I've discovered that cygwin never returns on reads (when
there's no char input of course), even when struct termio's
c_cc[VTIME] is set to a positive integer. I suppose this is a bug -
does anyone have a clue?


PS! I'm not subscribing the cygwin list - pls. reply to my private

I'm really interested for ANY answers about this.  I've exactly the same
problem.  My application seems to stick in the read function.  Anybody ever
experienced this?

I tried downloading the latest cygwin1.dll, but it makes my applications
print error messages about the dll version, and stop.

Any other idea?

PS: Svein, if you got answers at your personnal email, can you forward it to
me.  Thanks.

Sure.  That's what I've done.  But it still print the same error message.
BTW, I've this message for some shell applications like this:

bash-2.02$ pwd
D:\Cygwin-root\bin\pwd.exe: *** conflicting versions of cygwin1.dll
detected.  Use only the most recent version.

I don't understand this message because the DLL I use *is* the most
recent...   :-S

Well, the program doesn't lie.  You're using an older version of the
DLL somewhere.  You can use the Microsoft find files utility to find
where.
