RE: How change libtool rule of naming dlls from "cygFOO-version.dll" to "FOO.dll"?

 What is the effect of using
$ ln cygsurfit-1.dll libsurfit.dll
to create a link rather than simply rename?

Hello!

I have a problem. I write dll for Tcl and my dll must have fixed name
"libsurfit.dll" because of fixed initial procedure name, but using
libtool i have cygsurfit-1.dll :( 

Renamig cygsurfit-1.dll to libsurfit.dll don't solve the problem,
because i have another dll called "libfreeflow.dll" with name
"cygfreeflow-1.dll", which depends on "cyglibsufit-1.dll"

How can i change libtool rule of naming dlls from "cygFOO-version.dll"
to "FOO.
dll"?

Chaos.  

Windows does not support loading of DLLs through links.

Use the "-module" flag with libtool. That will create libsurfit-1.dll 
instead of cygsurfit-1.dll.

If you also want to get rid of the version number, use in addition the 
"-avoid-version" flag.

eg.

	libtool -module -avoid-version .......

No way?  You mean cygwin didn't invent symbolic links?!?  Who would
ever have guessed!

So now your point is instructing people in basic UNIX 101?

You should probably quit while you're not too far behind.

My intent was not to blame windows for not honoring a cygwin(?) 
invention, but for not having such useful functionality itself.

IIRC symbolic links predate cygwin, even predate linux for that
matter. In fact they predate windows as we know it today so it
is surprising that as so many other good ideas from UNIX made it
into MS products that links didn't. Hard or soft. That was my 
point.

Aye, that it would!

Even if it was "ln -s", it's hardly fair to blame windows for not honoring
a cygwin invention -- symbolic links.

OK, well then I guess I should do a little work to dispel some of your
distrust. :-)

After rereading this thread, I realize I'm wrong about this. :-(  When I
originally read the comment about linking, I thought "symbolic link", which 
is done so often with .so's on Linux/Unix.  That won't work because the 
Windows loader will not load DLLs through Cygwin's symbolic links.  However,
the original response did not include the '-s' flag for 'ln'.  Without it,
you get a "hard link" on NTFS formatted partitions and a copy everywhere 
else.  Windows will load either of these as a DLL (no surprise in the second
case at least ;-) ).

Sorry for the confusion (mine and that which I caused).
