[vsipl++] sourceryvsipl++-2.2 and Intel MKL version 10.2.5.035

[Brooks Moses]

Hello, Bill -

Yes, MKL changed the set of libraries to link to between versions 8.x
and the current 10.x version, and so the configure script in the current
versions of Sourcery VSIPL++ does not correctly recognize them.

We'll be adding support for MKL version 10.x in our next set of releases
this fall.

Meanwhile, if you do have a copy of MKL version 8.x available, you can
build the library against that, and then build your VSIPL++ applications
against MKL 10.x (with adjusted linker command line as appropriate).
The MKL API is sufficiently stable for this to work correctly, and with
static linking your applications will end up only using the code from
the MKL 10.x library.

(Alternately, if you look in the m4/lapack.m4 configure file, at about
line 193 you'll see the set of libraries checked for MKL; those are
currently "-lmkl_lapack -lmkl -lguide -lpthread".  You should be able to
hack those to point to the current appropriate set of MKL libraries.)

Let me know if that works for you, or if you have any other questions!

Thanks,
- Brooks
