Can I dynamically call a LGPL/GPL software in my closed-source application? [closed]

Answer 1

Correct me if I'm wrong, but I believe the situation you describe is like this:

1. You have a GPL or LGPL program, built as a separate executable, with no modifications made by you.
2. You are building a closed-source application that needs the functionality of the GPL or LGPL program.
3. In your program, you use your framework or OS facilities for running another, separate executable.
4. You are using the output of that executable in your program.

If that's the case, you're not actually linking to the GPL- or LGPL-licensed program. Thus, you're not bound by the license terms of that program. This is actually a fairly common, if complicated, way to avoid licensing issues with such executables.

However, it does violate the spirit of the GPL and the LGPL.
