Basic Linear Algebra Subprograms (Fortran)
Branch: CURRENT,
Version: 3.7.1nb1,
Package name: blas3.7.1nb1,
Maintainer: adamThe BLAS (Basic Linear Algebra Subprograms) are high quality "building
block" routines for performing basic vector and matrix
operations. Level 1 BLAS do vectorvector operations, Level 2 BLAS do
matrixvector operations, and Level 3 BLAS do matrixmatrix
operations. Because the BLAS are efficient, portable, and widely
available, they're commonly used in the development of high quality
linear algebra software, LINPACK and LAPACK for example.
This package contains the Fortran 77 reference implementation of BLAS.

Log message:
math/lapack: Restore build on DragonFly
Linking lapack with the gold linker fails with this error:
fatal error: sysroot=: must take a nonempty argument
DragonFly has been using the gold linker by default for a while now.
Since I don't have time to track down this linking problem, I'm going
to restore the build on DragonFly by setting an environment variable
that forces DF to use the classic GNU linker instead.
This was already fixed on math/blas which uses the lapack common
makefile, so just relocate the fix to lapack.

At this point in time, I don't know if BLAS is unique or if LAPACK
and others need the same workaround. If the latter, this variable
may need to be moved to the common LAPACK makefile.

Log message:
Changes 3.5.0:
* added Symmetric/Hermitian LDLT factorization routines with rook pivoting algorithm
* 2by1 CSD to be used for tall and skinny matrix with orthonormal columns (in \
LAPCK 3.4.0, we already integrated CSD of a full square orthogonal matrix)
* New stopping criteria for balancing.

This packages needs a Fortran 95 compiler to build, Fortran 77 is not
good enough.

Log message:
"fortran" > "fortran77" except where it is clear that it \
isn't F77.
"fortran" is alias of "fortran77" for now, but it will \
change later.
