LAPACK is a '''L'''inear '''A'''lgebra '''PACK'''age that provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.  LAPACK routines are written so that as much as possible of the computation is performed by calls to the BLAS.  The LAPACK libraries produced by ATLAS are not optimal.  Use the [[LAPACK]] package for optimal LAPACK libraries.

* [[GCC-3.3]] Benchmarking by the ATLAS maintainers indicated that, with the exception of Core Duo and Pentium M, compiling ATLAS with gcc-3.X [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27827 produced better x87 code than gcc-4.0]. But this performance regression appears to have been fixed in later versions of gcc-4.x, and the bug report has now been closed as 'RESOLVED'.

Introduction to ATLAS

BLAS are Basic Linear Algebra Subprograms written in Fortran. There are Level 1 (scalar and vector operations), Level 2 (scalar-matrix operations) and Level 3 (matrix-matrix operations) subprograms. ATLAS (Automatically Tuned Linear Algebra Software) will provide C and FORTRAN interfaces to a BLAS implementation optimized for a specific machine architecture. The ideal source of BLAS and LAPACK libraries are those provided by the microprocesor vendor such as AMD's ACML. However, these are not provided under a license that allows re-distribution without written consent from the vendor.

Configuration Information

Patch the package: 

patch -Np1 -i ../atlas-3.8.0-decl-fix-1.patch &&
patch -Np1 -i ../atlas-3.8.0-shared-libs-1.patch

Create a wrapper script to assist in building the shared libraries: 

export BUILD_DIR=CBLFS-build &&
mkdir -pv ${BUILD_DIR} &&
cd ${BUILD_DIR}

cat > war << "EOF"
#! /bin/bash
#
# war -- wrapper for the archiver
#
# Executed by ATLAS build as:
# full_path/war ARCHIVER ARFLAGS LIBNAME.a OBJS.lo

OBJ_DIR=${TOPDIR}/CBLFS/$LIBRARY

if [ ! -x $OBJ_DIR ]; then mkdir -p ${OBJ_DIR}/.libs; fi

$ARCHIVER $@

shift 3
for obj in $@ ; do
    lobj=$(echo $obj | sed 's/\.o/\.lo/')

    ln -sf ${PWD}/$lobj ${OBJ_DIR}/$lobj
    ln -sf ${PWD}/.libs/$obj ${OBJ_DIR}/.libs/$obj

Note

Either create a BUILD variable similar to the multiarch BUILD32, BUILDN32, and BUILD64 with compiler options or replace ${BUILD} in the configure flags below with your compiler options directly.
