libopenblas-dev does not include lapacke.h

[Florian Franzen]

On xenial (16.04) lapacke.h is not included with the development headers. Not sure why, as it includes "liblapack.so" never the less.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

It this bug tracker being reviewed by any maintainers?

Is there a better way to contact the package maintainers about this issue than through launchpad?

[Oliver (owlas)]

I'm also waiting for a fix. I might try and patch in the next couple of weeks. Do you have any experience of that?

Also affects Bionic (latest LTS).
LAPACKE symbols are not exported by the so.

[Matthew Arnold (matthew-arnold-1)]

Missing header also affects Eoan (latest current). Given the absence of LAPACKE in Bionic, the most likely explanation is that it was built with non-standard NOLAPACKE. Worth noting that the Bionic build of lapacke appears to link to openblas, but also links to reference blas & lapack, so it's not clear if the optimized routines are used or not (or if this makes a difference).

[Sébastien Villemot (sebastien-villemot)]

The lapacke.h header is already provided by the liblapacke-dev package. No need to duplicate it in OpenBLAS packages.

[Sébastien Villemot (sebastien-villemot)]

As the Debian maintainer, I also confirm that the optimized LAPACK routines will be used by LAPACKE if you install the liblapacke-dev package along OpenBLAS packages (provided the alternatives are correctly set).
