There's the usual misconception about the GPL. If you create an
application which is linked against the Cygwin DLL (or any other GPLed
library), but you only use the application in-house, there's no reason
at all to distribute the source code to your collegues. If one of them
really wants it, he can always ask you, right? Only if you provide the
binaries to customers or to the world in some way, you are supposed to
provide the sources codes as well in a GPL-compatible way.
In a publication I have offered to furnish on request the source code
and windows executable for a program that I personally run under cygwin.
Don't I have to use mingw for the publicly distributed version, or else
bundle the executable with cygwin source code? As I understand, simply
providing a link to the cygwin web site does not satisfy the license.
Well, if you don't want them to have to install Cygwin, then that's a
bigger issue than just licensing. Think of Cygwin like an OS. If you
want to create something that can run under Windows, not Cygwin, then
you have to build it for Windows, not Cygwin. I don't know that it is
even possible to simply "bundle" Cygwin with your application. Cygwin
isn't just some little collection of libraries or something. It's a
whole system that must be correctly installed on someone's computer.
If you really want Mingw (a free compiler and development environment
for Windows), maybe what you should do is just download and install
Mingw, and use that, instead of doing it through the Cygwin compiler
using a barely-supported option. (Then you should get help with any
problems you have over at Mingw's website instead of here.)
I hope I'm not out of line to suggest that on this list, but it sounds
like it's what you're really looking for.
