Upgrade LinBox to version 1.1.7

[malb]

LinBox? 1.1.7 was release in 2010, yet we are still running 1.1.6. It fixes a few issues which are relevant to Sage

• Install ​http://sage.math.washington.edu/home/malb/spkgs/linbox-1.1.7.spkg
• Apply trac_11718_linbox_1_1_7.patch​

NOTE This SPKG re-enables the Commentator and hence might break on OSX 10.4! Needs testing.

Status update

LinBox's Sage interface changed and this causes major problems. The attached patch is supposed to address this new interface but I cannot successfully link against liblinboxsage.so any more.

I get

    846                 import matrix_complex_double_dense
    847                 return matrix_complex_double_dense.Matrix_complex_double_dense
--> 848             elif sage.rings.finite_rings.integer_mod_ring.is_IntegerModRing(R) and R.order() < matrix_modn_dense.MAX_MODULUS:
    849                 if R.order() == 2:
    850                     return matrix_mod2_dense.Matrix_mod2_dense

AttributeError: 'module' object has no attribute 'MAX_MODULUS'

However, this is not a Python problem. If I remove everything from linbox.pyx except for

cdef class Foo:
    pass

and remove all references to LinBox except for one cimport of it in matrix_modn_dense and I empty out linbox-sage.C in the LinBox !SPKG except for

#include <iostream>
#include <gmp.h>

#include <cstdlib>
#include <vector>
#include <list>

#include "linbox-sage.h"

#include <linbox/util/commentator.h>

#include <linbox/blackbox/sparse.h>

#include "linbox/element/givaro-polynomial.h"

#include <linbox/matrix/blas-matrix.h>
#include <linbox/matrix/sparse.h>
#include <linbox/vector/sparse.h>

#include <linbox/algorithms/blas-domain.h>
#include <linbox/algorithms/echelon-form.h>
#include "linbox/algorithms/gauss.h"
#include "linbox/algorithms/smith-form-adaptive.h"
#include "linbox/ffpack/ffpack.h"
#include <linbox/solutions/rank.h>          
#include <linbox/solutions/det.h>
#include <linbox/solutions/solve.h>

#include "linbox/solutions/methods.h"
#include <linbox/solutions/minpoly.h>
#include "linbox/algorithms/double-det.h"
#include <linbox/integer.h>

#include <linbox/field/gmp-rational.h>
#include <linbox/ring/givaro-polynomial.h>

I still get this problem. Hence, I figure it should have something to do with the linking. That is, I assume LinBox overwrites some symbol or corrupts some memory somehow which makes it impossible to link against it from Sage.

However, I am out of ideas and steam. Hence, I'll give up on fixing this for now. But I will send an e-mail to the LinBox list.

PS: We also get the same UINT32_MAX error as #9511 on sage.math

The updated patch + SPKG seems to fix the issue, testing on sage.math now

Well, we further but we don't reach the finish line:

Interestingly, a related change about "commentator" apparently was ​helpful in trying to get Sage to build on FreeBSD.

[leif]

Just for the record:

There's a LinBox 1.1.6.p8 spkg with a couple of fixes at #12762 (currently still needing review).

Please close this ticket as a duplicate.

[vbraun]

Agreed

[jdemeyer]

Duplicate of what?

[malb]

It's a duplicate of #12883
