If I write a run-time environment based on some GPL'ed libraries and separately write an program interpreter which is passively used by the run-time environment, can a program (which is intended to be interpreted by the interpreter used in the run-time environment to perform some task) be under any license without restriction by the GPL? (sorry for my poor English)
It confuses me that "Does the fact that the interpreted program indirectly using the GPL'ed tool cause it be restricted under GPL?"
(There is a similar question. The asker of that question is the copyright holder in his scenario. Conversely, I can not be the copyright holder of the software (the run-time environment in this question) because it contains the code which is written by someone else and released under the GPL. )
