Hi Koldo,

Please note that EigenFFT license terms (GPL/LGPL) are not especially favorable from the Upp point of view. Of course the FFTW (one fft backend for EigenFFT) offers a commercially usable license option, but it comes with a price tag on it.

Best regards,

Tom


Hi Tom,

Since Eigen consist of headers only, it can be used in comercial projects without worrying about the (L)GPL Wink Also AFAIK at least on of the backends (kissfft) is licensed under the same terms as Eigen to assure compatibility.

Eigen authors say this about LGPL:
Quote:

When you distribute software that uses [unmodified] Eigen, the LGPL requires you to:
Say somewhere that that software uses Eigen, and that Eigen is LGPL-licensed.
Give a link to the text of the LGPL license.
See Section 3 of the LGPL.
That's pretty much the same as the 2-clause BSD license.

Please read the Licensing FAQ on Eigen website for further details and explanations Wink

Best regards,
Honza
