Re: gcc 3.4 and Octave/lapack problems

[Quentin Spencer]

I also installed Fedora Core 3 and saw the same problems. I looked this 
morning on the Red Hat ftp server and noticed the development branch had 
an updated version of lapack:
http://download.fedora.redhat.com/pub/fedora/linux/core/development/SRPMS/lapack-3.0-26.src.rpm
I downloaded the SRPM and rebuilt it, and the linear algebra functions 
like eig appear to be working correctly now (I'm using the same octave 
2.1.61 I compiled yesterday with no changes). I have attached the SPEC 
file. It appears to only change the -O flags. This updated release was 
in response to a separate bug that was reported in lapack:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=138447

I haven't done very thorough testing (I haven't tested Dmitri's Fortran 
code, for example), but I don't see any problems so far.

%description
LAPACK (Linear Algebra PACKage) is a standard library for numerical
linear algebra. LAPACK provides routines for solving systems of
simultaneous linear equations, least-squares solutions of linear
systems of equations, eigenvalue problems, and singular value
problems. Associated matrix factorizations (LU, Cholesky, QR, SVD,
Schur, and generalized Schur) and related computations (i.e.,
reordering of Schur factorizations and estimating condition numbers)
are also included. LAPACK can handle dense and banded matrices, but
not general sparse matrices. Similar functionality is provided for
real and complex matrices in both single and double precision. LAPACK
is coded in Fortran77 and built with gcc.

BLAS (Basic Linear Algebra Subprograms) is a standard library which
provides a number of basic algorithms for numerical algebra. Man
pages for blas are available in the blas-man package.

 - Total rewrite of the spec file
 - Added my own makefiles - libs should build better,
   static libs should work (and be faster than they
        would be if they had worked earlier ;)
 - No patch necessary anymore.

   blas and blas-man. "Obsoletes:" tag added.
   (oh - and as always: Dedicated to the girl I
   love, Eline Skirnisdottir)
