[Wien] wien2k_18 [-lm warning]

[Dr. K. C. Bhamu]

Now, I tried to install latest version of Wien2k on a cluster with mpiifort
and fftw3 and getting below warning during installation:

*ifort: warning #10315: specifying -lm before files may supersede the
Intel(R) math library and affect performance*

I have below setting.

$(FOPT) -L$(MKLROOT)/lib/$(MKL_TARGET_ARCH) -lpthread -lm -ldl -liomp5


Should I remove -lm or can continue?

I do not see any warning or error message at the  end of installation.


mkl version is 2013.

Kind regards
Bhamu
