This is >an >*unmodified* cygwin1.dll. If you distribute a binary then, under the GPL, you must make the source code available for the binary using the same method. It doesn't have to be available in the same archive. Look at the way the cygwin distribution does it. The sources are distributed separately. If you are actually distributing the cygwin DLL, then you need to also distribute the sources to the DLL as well. Again, the source code can be in a different package. So, in the above, you'd presumably have to provide the sources for ascom.dll, skeleton.dll, scope_client.dll, tests.exe, and cygwin1.dll. The easiest way to provide the sources to the cygwin DLL is just to use the cygwin source archives as can be downloaded from the cygwin setup.exe program. OTOH, we usually advise against people distributing the DLL since it will cause problems if your archive is extracted into an existing cygwin installation. It's usually better to just point people to the cygwin web site and have them install what is needed*. In that scenario, you wouldn't have to provide the sources for the cygwin DLL but you would need to provide sources for everyting else. >Can someone please advise me or tell me where to find out? > >I'd be happy to replace the need for this dll with static linking, >assuming that's even *possible* under cygwin. If it is, a pointer would >be appreciated. Static linking wouldn't buy you anything. You'd still need to provide the source code. The GPL FAQ is here: http://www.gnu.org/licenses/gpl-faq.html . You might want to familiarize yourself with it. cgf *Yes, I understand that this may install more than what you want but you still have to take the problem of existing cygwin configurations into account no matter what you do.
