[Pw_forum] how to avoid this warning ?

[lan haiping]

Thank you Axel,
I can avoid this warning with linking to espresso's self lapack package. But
it seems too slow than mkl library
I am trying to upgrade my mkl library to the latest,  and test whether it
will give this warning .

Thank you again for this long explanation .
