Dear Guix,

I'd like to add 'nlopt', a library for non-lineair optimizations.
By passing "--enable-shared" to the configure script, it generates
a shared library as well as a static library.  Otherwise, this patch
is pretty standard.

Thanks for your time.

Kind regards,
Roel Janssen

Looks good, but for some reason I can't apply the patch to my source
tree. Does it work for you?

Same for me, there is some problem with this patch.

Dear Leo,

Thanks again for reviewing my package.  I really appreciate your
time and effort. :)

Strangely enough, I couldn't apply it either.  I don't know what
happened..  I regenerated the patch, and now I was able to apply it to
my source tree.  Hopefully it works for you too now.

This problem has already happened to me last year.  I suspect it is/was a
bug in Git.

I've attached the diffoscope report (HTML) between the first two patches
in this thread.

The diff header in the 'bad' patch says that the hunk applies to 7
lines.  In the 'good' patch, the header instead says 6.

The 'bad' patch can be applied when that parameter is changed to 6.

I wonder if the bug can be reproduced?

Do you mean “attached” like in email attachment?  If so then I don't see
the attachment...

Where did you get that it is lgpl3?  COPYING names GNU LGPL version 2.1
or later and MIT (which is 'expat').  I quickly looked at the source
files: most of them do not have a license header, the others use the
mentioned licenses, so I think it should be:

  (license (list license:lgpl2.1+ license:expat))

Thanks for your carefulness.

On the website they explain it as follows:  A part of the code is "LGPL"
(no version specified) and a part is MIT.  The most "restrictive" (as
they call it), determines the license of the whole package (and thus
it's "LGPL").

I actually couldn't find which version of the LGPL, so I assumed the
latest variant.  The COPYING file does mention version 2.1 or later.
The same file also reassures that the entirety of the package is
governed by the LGPL (v2.1+):

http://ab-initio.mit.edu/wiki/index.php/NLopt_License_and_Copyright

I attached a new patch.

Kind regards,

The reason I did not include in Guix is because of unclear licensing on

I’m looking at packaging NLOpt for Guix, a free software GNU/Linux
distribution.

I noticed this paragraph in luksan/COPYRIGHT:

    Subroutines PBUN, PNEW, PVAR, PSEN, Copyright ACM, 2001. The original
    versions were published in Transactions on Mathematical Software, 
    Vol.27, 2001, pp.193-213. Here are the author's modifications. They
    are posted here by permission of ACM for your personal use. Not for
    redistribution. Subroutines PLIP, PSEN, Copyright Jan Vlcek, 2007. 
    The remaining subroutines, Copyright Ladislav Luksan, 2007. Many of  
    sparse matrix modules were prepared by Miroslav Tuma.

My understanding is that these subroutines cannot be redistributed nor
modified by anyone; what do you think?

Thank you,
Ludovic.

Could you check if this is still relevant, and possibly get in touch

Hi Ludo’,

I think the licensing page on the website is pretty clear:
http://ab-initio.mit.edu/wiki/index.php/NLopt_License_and_Copyright

From the page:
> The NLopt library is under the GNU Lesser General Public License
> (LGPL), and the copyrights are owned by a variety of authors.

And:
> The combination of all of this software is under the conjunction of the
> license terms, and in particular they are limited by the most
> restrictive of the licenses for the portions, which in this case is the
> LGPL. (The other portions of NLopt are under LGPL-compatible,
> less-restrictive licenses like the MIT license. So, if you remove the
> LGPL portions, which are currently code by Ladislav Luksan, the
> remainder reverts to a looser license.)

What's not clear from that page is which version of the LGPL.  But
that's cleared up in the COPYING file of the source repository.

Kind regards,
Roel Janssen

Still, according to luksan/COPYRIGHT, “[s]ubroutines PBUN, PNEW, PVAR,
PSEN” are “for your personal use […] [n]ot for redistribution”.

So my understanding is that we need to remove those four subroutines.
The rest in that directory is LGPLv2.1+.

WDYT?

I don’t see it at
<https://libreplanet.org/wiki/List_of_software_that_does_not_respect_the_Free_System_Distribution_Guidelines>.
Debian has a package: <https://packages.debian.org/source/sid/nlopt>.
Could you check if they apply any patches?

Besides, I suggest reusing the bits about Guile bindings from the patch
I sent.

Thanks,
Ludo’.

I agree to your understanding.

A little later in the same file I found: "This library (with exception
of PBUN, PNEW, PVAR, PSEN) is a free software".

I haven't found any patches.  So I dug a little deeper and attempted to
remove them myself with a patch, but I haven't been able to find these
subroutines.

I ran the following commands on the root of the source directory:
grep -i -r "pbun" .
grep -i -r "pmin" .
grep -i -r "psen" .
grep -i -r "pvar" .

And I haven't found the routines.  So I think we're safe.  That could
also be why Debian doesn't have a patch for this either.

Shall I prepare a new patch?

Indeed.  Actually, luksan/README states:

  [We also did not convert the PMIN, PBUN, PNEW, or PVAR subroutines
  since these were published in ACM Trans. on Math. Software (TOMS) and
  are subject to the non-free ACM licensing conditions.]

So indeed, the COPYRIGHT file is confusing, but we’re safe.

Sorry for the false alarm.

Yes please.

“(method” should be indented below the “r” of “origin” (I think this
pattern also appears in the R patches you recently submitted.)

Thank you!

Ludo’.

PS: I’d be happy to add configuration files for editors other than Emacs
    so that everyone has their indentation and stuff properly set up.

I've been submitting most packages this way.  Should I align (method
...) to the r in origin for all packages in the future?

Thank you!

Yes, 'method' is a sub-expression or 'origin', not of 'source', and it
should be aligned accordingly.

I suppose you don't use Emacs; may I ask what editor do you use?

I use Emacs.  So, how did it adjust indenting to source instead of
origin you might ask next..  The answer is: I did that manually :-).
