Dynamically linking libraries/headers is not considered as making your program fall under the GPL. However, the rules are not hard and fast and rely a bit on common sense and your intent. A clear example would be statically linking someones GPL'd library into your commercial application -- this would "pass the GPL along". But dynamically linking to standard libraries would not be included. See : http://www.gnu.org/copyleft/gpl-faq.html Compiling with gcc infers no requirement to license under the GPL. >If I want to sell commercially my app, do I >have to give away the source too? all the source or just the GPL bits? >if I don't include the source do I have to acknowledge the GPL stuff >or include the GPL copyright notice etc etc? You have to release under the GPL any GPL software you use/modify. For a good example, see the TIVO. They release the changes they have made to the PPC kernel (http://www.tivo.com/linux/index.html), but have large amounts of non-GPL code that runs on top of that kernel which they don't release. -i [EMAIL PROTECTED] http://www.wienand.org ********************************************************************** CAUTION: This message may contain confidential information intended only for the use of the addressee named above.
