[Wien] Question about WIEN2k_07 siteconfig_lapw compiling

[Gerhard Fecher]

There should be both
libmkl_lapack.a for static linking (automatically if -lmkl_lapack is given)
and
libmkl_lapack64.so (libmkl_lapack32.so) for dynamic linking (this may need also other libraries from the mkl package, I did not check the latest version, some seem to have new names.)

It is indeed strange that the lapack has in the static version no _em64t, but the mkl (libmkl_em64t.a), wheras the dynamic version of mkl (libmkl.so) has no _em64t.

I think the dynamic .so libraries have to be execuatble for users.

Ciao
Gerhard

cd /opt/intel/mkl/9.1.021/lib/em64t
ls -als

Look what lapack librarries exist there. Most likely *mkl_lapack64*
is not present, but just mkl_lapack. Use whatever is present there
(lithout "lib" at the beginning and without .so at the end)

(Intel labels only the Itanium-libraries with "64", Intel 64-bit systems have
"em64t" or nothing at all)
