.a to .lib converting

Post by Alireza Ghasemi
Hello,
I want to use some cygwin .a libraries with other environments(like VC++) as
static .lib files.is this possible?

Yes.

Post by Alireza Ghasemi
Can I convert .a files to windows static libraries?

Yes.

If possible,what program do I need?

This was discussed before, though I'm not sure what the correct search
terms would be. I believe you can simply use "mv libblah.a libblah.lib".
<http://cygwin.com/faq/faq_3.html#SEC103> might help, too.

P.S. Your space key seems to be malfunctioning...

Yes.

Or no. ;-)

Actually, this is the answer to the opposite question. The answer to that
is as the FAQ states. Using Cygwin .a's with VC++ isn't as easy, since
they are going to pull in 'cygwin1.dll' and this cannot currently be
initialized properly by non-cygwin programs. Of course, this subject
has also be discussed in the email archives. If interested, Alastair
Growcott suggested a "workaround". If you're interested in it, see
<http://sources.redhat.com/ml/cygwin/2004-06/msg00274.html>. I'd
recommend directing questions about this to him, though it's worthwhile
to cc the list for posterity. :-)

Yeah, I noticed that. :-)

Eh? Your response below points to a "yes", AFAICS...

Ditto.

Umm, right. That's why I said "might help" rather than point the OP
directly to it... :-)

Ah, yes, this is exactly the message I was thinking of (though I didn't
recall it being this complicated). Thanks for including a pointer to it.
BTW, we're talking about linking C here, not C++. The name mangling
differences will make C++ linking much more painful, IIUC.

FWIW, someone else has mentioned working on the DLL initialization code
quite recently -- he might benefit from this pointer as well.
