I would like to know following from a reliable source.
I have searched in several Newsgroups but I found only personal opinions and nothing formal.
I have a Postscript File and would like to convert this to PDF using Ghostscript.
Now I have 2 Possibilities :
1) Write a simple EXE which starts GhostScript with the parameters required in order to convert to PDF.
2) Write a simple EXE using the GhostScript API
Must both EXE be licensed under the GPL? Or just the second one, because GhostScript has been linked?
Is there a possibility to include GhostScript within a Setup of commercial "closed Source" Software? Or do I have to put a separate GhostScript-Setup on the CD?
I would like to create my own personal PDF-Printer for some personal reasons, although you can find a lot of Printers here in sourceforge.
It would be no problem to license this Printer(Driver) under the GPL. But I would like to put it in ONE Setup with commercial closed-source Software.
Would this be legal?
Do I have to create a separate SourceForge-Project for my own Printer-(Driver) or is it enough to provide the SourceCode if someone is asking for?
It would be very helfpul is someone could tell me the truth, cause I heard several totally different opinons before.
(on told me the EXE in 1. can be closed, another one told me it must be GPL etc.)
You can use GPL Ghostscript in a commercial product as long as your release the source code for your product under the GPL. If you don't want to do that, you need a separate license.
