Whether your use of Cygwin means your program also needs to fall under the GPL 2. Distribution of the Cygwin DLL and its utilities If what you describe above about your usage of Cygwin is correct, then I believe (1) is not an issue for you. However, (2) still applies since you cannot distribute GPL'd software without providing the source as well. But this is getting a little off-topic for this list. If you'd like to follow-up on this more, it's best to take it the Cygwin Licensing list, keeping in mind that no one there is a lawyer either and free legal advice is worth exactly what you pay for it. ;-) -- Larry _____________________________________________________________________ A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting annoying in email? -- 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
