Hi,

I am a new user of Gmsh and I have a question regarding its licensing. I was wondering whether the Gmsh API is also under the GPL license meaning that I can not use the Gmsh API in a closed-source Python code. Is that right?


Question : If a programming language interpreter has a license that is incompatible with the GPL, can I run GPL-covered programs on it?

Answer : When the interpreter just interprets a language, the answer is yes. The interpreted program, to the interpreter, is just data; the GPL doesn't restrict what tools you process the program with.

However, when the interpreter is extended to provide “bindings” to other facilities (often, but not necessarily, libraries), the interpreted program is effectively linked to the facilities it uses through these bindings. The JNI or Java Native Interface is an example of such a facility; libraries that are accessed in this way are linked dynamically with the Java programs that call them.

So if these facilities are released under a GPL-incompatible license, the situation is like linking in any other way with a GPL-incompatible library.

Thank you,
Niloufar
