Description Jeroen van Meeuwen 2008-05-22 16:19:36 UTC
Spec URL:
Description: Perl interface to the cephes math library

Additional Info:

EL-5, F-8, F-9 and rawhide are targeted; koji scratch builds below:

- (dist-f8-updates-candidate - FAILED miserably, may need some help there)
- (dist-f9-updates-candidate - partially succeeded at time of submission)
- (dist-f10 - partially succeeded at time of submission)

As far as the partially succeeded builds goes; there's an OOo build running on ppc{,64} at this moment... ;-)

Comment 1 Jeroen van Meeuwen 2008-05-22 16:37:04 UTC
I forgot some pretty stupid things in the .spec


Comment 2 Nicolas Chauvet (kwizart) 2008-05-28 12:46:22 UTC
 - starting review -

Comment 4 Nicolas Chauvet (kwizart) 2008-05-28 13:25:50 UTC
Ok, so I have a design question.
This perl module claims to be an interface to the cephes math library.
This library is quite old and not really maintained as seen here:

So I wonder if either :
 - some functions of the Cephes aren't merged in nowadays math library (-lm ?)
 - If the cephes library could be built separately to be available to other
(non-perl) project. (it seems used inside grace and labplot at least) 
 - If the license of the Cephes code is clear enough:

Of course, using shared version of the library may prevent some duplicate works
in the maintainability of such library, as i expect... It would be interesting
to ask to the related project.

Unfortunately , theses question already appeared on the ml and i don't see any
final conclusion here. So i don't know how is licensed the cephes code source.

Comment 5 Patrice Dumas 2008-05-28 13:38:06 UTC
There are some files in grace (LICENSE.cephes,
explaining that cephes can be considered GPL.

But regarding cephes being built seprately, I think that it would
be much better. Still the perl module would need the source to build
the swig interface (unless I am wrong), but even in that case we could
do a *-source package and reuse it for the swig bindings. 

Comment 6 Nicolas Chauvet (kwizart) 2008-07-03 00:14:55 UTC
Any news from upstream project ? if they could handle a shared version of cephes ?
Can you attach the LICENSE.cephes and, maybe we can block
FE-Legal if there is a remaining question.

Comment 7 Jeroen van Meeuwen 2008-07-04 19:29:31 UTC
I've not checked yet (/me is on vacation)

Comment 8 Patrice Dumas 2008-07-06 07:58:03 UTC
There are no questions with regard with license, at least no more 
than for grace. Files are at:

Comment 9 Jeroen van Meeuwen 2008-07-11 12:06:28 UTC
Please continue the review as possibly using a shared version of cephes or the
math library instead isn't suitable to be addressed in the initial package review.

Comment 10 Nicolas Chauvet (kwizart) 2008-07-17 08:57:28 UTC
Build Error when tested in mock Fedora 9 i386
(whereas local rpmbuild worked).
This might be caused by a parallel make problem as the libmd.a is created after
this linking error.
builddir/build/BUILD/Math-Cephes-0.45/libmd/libmd.a: file not recognized: File
collect2: ld returned 1 exit status
Just remove %{?_smp_mflags} and add a note.

For the same version, arch: I also have lot of:
Cephes_wrap.c: In function '_wrap_cmplx_r_set':
Cephes_wrap.c:1326: warning: null argument where non-null required (argument 1)

Comment 13 Nicolas Chauvet (kwizart) 2008-10-28 15:30:23 UTC
I cannot review this.
Actually I'm facing the same problem with perl-EV (#448613)
And I'm not strong enough in perl to enforce the request of having libraries built shared.

Comment 14 Jan Klepek 2009-08-31 17:24:02 UTC
any update?
there is new version of perl-math-cephes in cpan

Comment 15 Terje Røsten 2010-02-16 16:05:36 UTC
I consider a shared cephes library nice to have, but not a blocker. 

The library is for math functions which are > 200 years old, there should not be a need to update this software every year.

Import the package and open a ticket against perl-Math-Cephes with a shared libs request, add info about grace and labplot.

If no one objects on this point I will do the review.

Any way, please update to latest release.

Comment 16 Terje Røsten 2010-03-01 10:15:02 UTC
Hi Jeroen, could you please update to latest release Math-Cephes-0.47:

Comment 17 manuel wolfshant 2010-07-16 03:11:44 UTC
Jeroen, are you still interested in this package ? If so, please update the spec to use the most recent release of Math-Cephes and, unless Terje wants to do it, I'll try to do the review.

Comment 18 Jason Tibbitts 2010-11-01 20:10:13 UTC
It's been a few months since the last comment, and over two years and several questions with no response from the submitter.  I'm just going to close this.
