QB64 Phoenix Edition Licensing information
QB64-PE makes extensive use of third party libraries to provide functionality. These third party libraries have their own licenses that you must respect when distributing any programs compiled by QB64-PE.
As a general note, almost all third party libraries used by QB64-PE are either MIT,
Public Domain, or some other permissive license. Meeting their requirements can
be done by simply distributing the licenses in the ./licenses folder with
your compiled program.
A few of the libraries are LGPL and require more careful handling to meet their license requirements (either by providing source code or object files before linking). Those are noted on this page and avoidable. Note that QB64-PE does not give the option of using dynamic linking, all third party libraries are statically linked.
Additionally, QB64-PE contains logic to avoid compiling in third party libraries if they are not used by the program, those situations are noted on this page. If a component is not compiled into your program then you do not need to meet its license requirements.
