slacgv missing in plasma 2.3.1 compile

[ekang]

I tried to compile PLASMA 2.3.1 and have several undefined symbols:

slacgv_
slag2d_
dlacgv_
dlag2s_

LAPACK 3.3.1 seems to have both dlag2s and slag2d, but not slacgv or dlacgv. Where can I find slacgv and dlacgv?

Hello,

can you send us the complete error, because slacgv and dlacg don't exist. [cz]lacgv are routines to conjugate complex matrices.
By the way, the new PLASMA release will be released soon, so you can wait a few minutes/hours to take the new one, if you are interested in.

Hi Mathieu,

The functions slacgv and dlacgv are referenced in the custom LAPACKE distribution found at:

http://icl.cs.utk.edu/projectsfiles/pla ... apacke.tgz

which I downloaded after reading this post, which helped resolved some other undefined symbols:

Looking forward to the new PLASMA release, thanks - Ed

Hello,

Ok, so this is a mistake in LAPACKE, because these function have no meanings in real precisions. We will fix that and update the package.
I let you know as soon as it is done.

I have another remarks, you don't need to compile PLASMA with scalapack and mpi. It's only for shared memory.

Hello,

you can try to delete the lapacke archive in your plasma installer directory and re-install plasma again. The fix has been integrated.

Thanks,
Mathieu

Success! The latest version of PLASMA (2.4.0) has compiled successfully on our system.

Thank you.

I am really glad to hear that.
Let us know how you like it.
