I don't think it will.  This document tells you how to build an
application that does not rely on cygwin in any way.  Unless I'm missing
something, this is not what was being asked for.

The real answer is "You can't do that.  Sorry."

Subject: Static version of Cygwin DLL?


Hi there,

I need to build an executable using Cygwin (gcc, ld etc.), but I need it not
to depend on cygwin1.dll. I tried to link directly with /usr/lib/libcygwin.a
:

gcc -static -o ../bin/test.exe ../obj/test.o  -L/usr/lib -lcygwin

but the resulting executable still requires the presence of cygwin1.dll on
the path. I've searched the archives, but did not find anything closer than
this:

http://www.delorie.com/archives/browse.cgi?p=cygwin/1998/02/13/01:17:34

it's too old, I thought maybe there could be something more up-to-date (I
tried Mumit's site as well, but it deals mainly with the problem of building
DLLs with Cygwin).

Any hints or directions to other documentation about this would be greatly
appreciated.

TIA.

Andre

[Andre Oliveira da Costa]

Hi everybody,

thanks for all the posts. Now I understand that, even if there was a
libcygwin1.a, linking statically to it could bring me licensing problems. I
also learnt that, if I'm ok with dropping POSIX, I could use the -mno-cygwin
switch (in this case, I'd be Cygwin license-compliant, right?). I guess that
covers it all.

Thank you all for your time.

Best,

Andre Costa

I'm sorry, but this is completely wrong.  There is no static version
of the cygwin runtime, period.  The -mno-cygwin option tells gcc to
cross-compile to the MSVC runtime (i.e. the result is *not* a cygwin
application).  What you *think* is the "static cygwin" is really just
the import library for the DLL

	The only way to force Cygwin to not depend on cygwin1.dll is to 
set the -mno-cygwin switch in your compile line 
(eg gcc -c -ofoo.exe foo.c -mno-cygwin).

	By forcing the elimination of cygwin1.dll using -mno-cygwin, 
you can then do this:

	gcc -ofoo.exe foo.c -mno-cygwin -lcygwin

	The default paths already scan the usr/lib directory.  It is 
the usr/lib directory that has the static version of cygwin 
(libcygwin.a).

	Peace,

		Paul G.

Well, a static version of the Cygwin POSIX runtime can't be done; but,
if you only need ANSI and not POSIX -mno-cygwin will allow Cygwin1.dll
not to be used.

And, if you could, there would be potential licensing problems anyway.

You can't do that.
