Actually, you can easily bundle a program with the Cygwin DLL and have it work fine. You don't need to install the whole system. That doesn't mean it's a good idea, however, since your soon-to-be-out-of-date DLL could cause confusion with an existing Cygwin application. >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.) The MinGW cross-compiles are not "barely supported". They are included in the distribution precisely so that people can build pure-windows programs under Cygwin. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
