Re: Copyright OTB

Well, here is what I understand:
  • ITK sources are under Apache v2, except a few modules that can link with FFTW (optional dependency, GPL)
  • In OTB, there is one binary (otbapp_DomainTransform) that links with ITKFFT module.
  • In Debian, since ITK is built with FFTW, the whole package is licensed under GPL
I am not sure what is the Debian policy in such case (mixed license). I would consider logical that since OTB links with ITK, licensed under GPL in Debian, then OTB in Debian should also be released under a GPL license.

However, you can also modify the Copyright description to mention that the file Module/Applications/AppDomainTransform/app/otbDomainTransform.cxx actually links to FFTW and should be GPL v3  (v3 is compatible with Apache v2).

Regards,

Guillaume

I may have noticed a mistake on the license for OTB debian packages.
Since they link with Debian ITK, which is licensed under GPL (built
using FFTW), the OTB debian packages should be licensed under the GNU
GPL v3 (for compliance with Apache v2 license).

Can you be more specific?

Note that we only documented the license for the source, not for the resulting binaries.

Kind Regards,

Bas
