Thanks for all the replies.
To clarify some of the points raised in all the responses: o My application is a GTK+ based GUI in a Windows environment o The GTK+ libraries are downloaded and used as-is by me, i.e. as dynamic libraries. Note that these are dynamically-linked libraries resolved, I believe, at load-time, and are not dynamically-loaded, which can be resolved at run-time. To be more specific, I am using the GTK+ APIs as such. I am not doing LoadLibrary() or GetProcAddress(), which are the equivalent of the Unix dlsym(), dlopen(), etc. o I am distributing a zipfile containing my .exe, .bat and all the GTK+ .dll files necessary for smooth execution of the GUI. o Note that I am not telling the user to install GTK+ themselves. I am distributing the GTK+ .dll files untouched in order to simplify things for my user. Now, to ask specific questions based on your responses: After reading all the responses, I am still a little confused (I may have misunderstood the subtleties here). On the one hand, I have understood that since I am using dynamic GTK+ libraries untouched, therefore my application can be closed-source. On the other hand, I am distributing the libraries (I am not asking the user to install it themselves). Can this be construed as a modification to GTK, thus requiring me to offer access to the sources? Final question: If I do have to provide access to GTK sources, I cannot just point the users to the GTK.org website. I must actually maintain a set of sources, attempt to compile them into .dll's, and point the user to them?

Priya, in case you were asking whether using GTK+ (as a dynamically-loaded shared library) requires you to provide the source code of your _application_, then the answer is No. If GTK+ was GPL (rather than LGPL) then the answer would be Yes. -- [EMAIL PROTECTED] www.murrayc.com www.openismus.com
