[Debian-astro-maintainers] Bug#856706: cpl-plugin-sinfo: copyright violation

[Dima Kogan]

Source: cpl-plugin-sinfo
Severity: serious

Hi. cpl-plugin-sinfo is using some numerical routines from numerical
recipes. These are NOT free software and may not be used in a free
software project.

For Debian, you can elide these sources. It would also be great if you
talked to upstream so that they stop violating copyrights also.

Look at sinfo_svd_compare() in

  sinfoni/sinfo_svd.c

A later version of the book chapter this function came from lives here:

  http://numerical.recipes/webnotes/nr3web2.pdf

You can see many similarities. If you look at the older version of the
book, you will see 100% similarities.

The copyright statement is here:

  http://numerical.recipes/public-domain.html


I haven't done a thorough search, and it's possible SVD implementation
isn't the only violation here. It would be great if you looked more
thoroughly.

Thanks
