The problem is that I have a lot of users on the 4.x release(s) of the OS, and have binary apps that I'm supporting for them. Linking static is an option, but does ugly things to the file sizes. Thus, wondering if I can link the other way and still have it run on a 4.x box. I guess it depends on what the application is and what dependancies there are. -- -- Karl Denninger (karl@denninger.net) Internet Consultant & Kids Rights Activist http://www.denninger.net Tired of spam at your company?
