Compiling with ifort: cannot find -lmkl_em64t

[Widner__Max]

Hello, my experience with Fortran is pretty limited so I apologize in advance if I don't provide all the necessary information. I'm trying to run a makefile but getting errors stating "cannot find -lmkl_em64t." There are other issues but I'm not sure if they're detrimental or not. Here is my makefile:

**************************

libs =

OPT = -O3 -xT -r8 -i8 -FR -WB -save -static -zero -nus -mp -double_size 128

COPT =

LOPT = -Wl,-rpath,${TACC_MKL_LIB} -L${TACC_MKL_LIB} -lmkl_em64t -lc -nus

OBJS=  \

ser_v10_whitecone_correctPSD.o gasdev.o rk4.o osc_stm.o \

  osc_deriv.o

ser_v10_whitecone_correctPSD.exe: $(MOBJS) $(OBJS)

ifort -o ser_v10_whitecone_correctPSD.exe $(LOPT) $(MOBJS) $(OBJS)

.SUFFIXES:      .o .f .f90 

.f.o:

ifort $(OPT) -c $<

.f90.o:

ifort $(OPT) -c $<

.c.o:

icc $(COPT) -c $<

And here are the errors I'm receiving:

Like I said, I'm pretty new to this so I'm not sure if I'm providing enough information or not. Any advice would be greatly appreciated!

That library name was very likely changed many years ago - and I'm not sure if that was ever a provided library. Try just -lmkl . If you need more help, see the MKL forum or the MKL Link Line Advisor.

Indeed, as Steve suspects, your makefile is several years older than your compiler. You should probably use -lmkl_intel_lp64 instead of -lmkl_em64t if integer arguments to MKL routines are 32-bits long, but it is best to consult the MKL Link Line Advisor. Once you find the proper set of libraries to use, you should probably update your makefile accordingly.

Instead of -xT, use -xSSE3.

Thank you both for your input. I assumed it was something along these lines. I will check the references you both mentioned. Thank you!
