MATGEN symbols are not included in Debian binary
Forwarded: not-needed
Last-Update: 2016-03-24
The libopenblas binaries do not include libmatgen code, so don't mark them as
exported and don't test for their presence (in linktest).

Create shared libraries lib{blas,lapack}.so.3
Forwarded: not-needed
Last-Update: 2020-07-29
* It is done so that duplicate code with libopenblas.so.0 is kept as low as
possible. Only the symbols from the external BLAS/LAPACK API are incorporated
in the shared libraries. The rest is obtained by dynamic linking against
libopenblas.so.0. This also gives access to some extra OpenBLAS symbols, in
order to differentiate it at runtime from other BLAS implementations (see
#960728).
* See also override_dh_shlibdeps in debian/rules
* Also order the files when calling `ar' or $(CC), to make
the build reproducible (see #824639)
* Also link the shared blas and lapack against gomp (see #945791)

Adapt build system for the absence of lapack-netlib/ and relapack directories.
Forwarded: not-needed
Last-Update: 2017-07-27
Instead use the binary provided by package liblapack-pic, stripping from it the
symbols that are overridden by OpenBLAS.

Remove warning about OpenMP

Last-Update: 2014-02-17
This warning is annoying when the library is built with pthreads.

Various fixes for kFreeBSD shared library
Forwarded: not-needed
Last-Update: 2014-08-05
Under kFreeBSD, give a SONAME to the shared library and install it. Also link
it against libm.
Simply use the same code as Linux for all these operations.

Use flags suitable for armhf port when TARGET=ARMV6
Forwarded: not-needed
Last-Update: 2015-04-29
See debian/rules for an explanation of why we can't use TARGET=ARMV7 on armhf.
Also, if we don't explicitly set the -march and -mfpu flags, the resulting
static libraries crash with SIGILL (reason not yet elucidated).

openblas (0.3.10+ds-2) unstable; urgency=medium
* lib{blas,lapack}.so.3 are again dynamically linked against libopenblas.so.0.
This restores the pre-multi-flavour behaviour.
Incidentally, this brings back the possibility of checking at runtime for
the presence of openblas_get_config symbol. (Closes: #960728)
* fix-dynamic-arch-gemm-crashes.patch: new patch (Closes: #966175)
