Dear all,

I have been trying to use the "c++ mathlink".
The linking process works great till I link my c++ program with
Intel's MKL 10.0 libraries.
There a similar bug in another system that is caused by the fact that it
uses MKL 9 (I think that also Mathematica uses the same version).
Is there a solution for Mathematica?
Help is much appreciated. Contact me for details on a solution
in the other system.

Snir

What exactly is the problem? Is the problem with the link phase - such
as some sort of name clash?

I am able to activate the link with Install["name of C++ source"]
But trying to active any linked function that uses MKL results with an
error.

I cannot rule out the possibility that this is unrelated to MKL 10.
But for calculation that don't involve MKL 10 calls every thing works
fine.


Thanks a lot.

So let's get this quite clear. You have a Mathlink program that seems to
work if you don't call a function from MKL 10, but crashes if you do
(what error does it produce).

What OS are you running on?

Is MKL 10 supplied as a DLL? If it is, are you sure it is accessible to
the MathLink program?

I take it the link phase produced no diagnostics.

Are you using a 64-bit machine with 64-bit OS, or a 32-bit machine? If
you are using a 64-bit machine, are you using the 64-bit version of this
library?

Hi Again,

Thanks for your assistance.
As to your questions:

1. I work on fedora 12.
2. MKL comes with link to libraries (.so). The thing is that Mathematica
also uses with those libraries only with version MKL 9 (they are on the
Mathematica folder).
3. It is 64-bit. Yes I am using the 64-bit version.
4. The Error I get is that - The link was lost.

Thanks again

Snir
