Bug#811073: RFS: lbfgsb/3.0-1 [ITP]

Package: sponsorship-requests
Severity: wishlist

Dear mentors,

I am looking for a sponsor for my package "lbfgsb"

 * Package name    : lbfgsb
   Version         : 3.0-1
   Upstream Author : Ciyou Zhu, Richard Byrd, Jorge Nocedal and Jose Luis Morales
 * URL             : http://users.iems.northwestern.edu/~nocedal/lbfgsb.html
 * License         : BSD-3-clause
   Section         : math

It builds these binary packages:

 liblbfgsb-dev - Limited-memory quasi-Newton bound-constrained
 optimization (static library)

 liblbfgsb0 - Limited-memory quasi-Newton bound-constrained

 liblbfgsb0-dbg - Limited-memory quasi-Newton bound-constrained
 optimization (debug symbols)

Note that upstream's tarball [1] contains precompiled binaries, and is
also a minor tarbomb. I have therefore repackaged it. You will find
that my orig tarball is a strict subset of upstream's.

My package includes two patches:

 - replace-linpack-with-lapack.patch: The library code originally uses
   LINPACK (from an embedded copy). Since LINPACK has largely been
   superseded by LAPACK, this patch replaces calls to the former with
   equivalent calls to the latter. Specifically, dpofa is replaced by
   dpotrf, and dtrsl is replaced by dtrtrs.

 - silence.patch: The library's documentation indicates that it will
   only write out messages when the iprint flag is greater than
   zero. There are two places where writing still happens
   unconditionally, which this patch fixes. A similar patch was also
   applied by the SciPy project (see their issue 3238).

I've used the patched package on and off for the past few years and
have not encountered problems.

To access further information about this package, please visit the following URL:


Alternatively, one can download the package with dget using this command:

 dget -x http://mentors.debian.net/debian/pool/main/l/lbfgsb/lbfgsb_3.0-1.dsc

More information about lbfgsb can be obtained from [2].
