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.

QB64 Phoenix Edition Runtime

This is the licensing of the provided QB64-PE runtime that compiled programs make use of.

Library	License	License file	Location
libqb	MIT	license_qb64.txt	internal/c/libqb.cpp, internal/c/libqb/, internal/c/qbx.cpp

Windows C and C++ Runtime

On Windows MinGW-w64 is used to compiled the C++ code produced by QB64-PE, and some runtime components are compiled into your code. On Linux and Mac OS this section does not apply.
