trouble when running the fft examples

As the subject says. I have sourced the intel64 .sh file...libiomp5.dyld is in /opt/intel/Compiler/11.1/088/lib
I'm stumped (as usual!).

Here's what I get in directory /opt/intel/Compiler/11.1/088/Frameworks/mkl/examples/fftw3xf

bash-3.2$ make libem64t interface=ilp64
make lib _IA=em64t
rm -rf ./_results/intel_ilp64_parallel_em64t
test -d ./_results/intel_ilp64_parallel_em64t || mkdir -p ./_results/intel_ilp64_parallel_em64t
ifort -vec-report0 -i8 -I../../include/fftw -c source/mkl_fftw_examples_support.f -o _results/intel_ilp64_parallel_em64t/mkl_fftw_examples_support.o

Thanks for setting me straight.

Hi,

It's strange because libiomp5.dylib (together with all MKL-libraries) should be located in the
/opt/intel/Compiler/11.1/088/Frameworks/mkl/lib/em64t
directory

Hi,

It's wrong. libiomp5.dylib is located in the/opt/intel/Compiler/11.1/088/lib as Peter mentioned, because only Professional Compiler distribution exist under Mac OS X operating system.

Best regards,

Artem

Hello Peter,

I tried to follow your steps and doesn't obtain any issues. Please see the log of my actions below:

# bash

bash-3.2# source /opt/intel/Compiler/11.1/088/bin/ifortvars.sh intel64

bash-3.2# make libem64t interface=ilp64

rm -rf ./_results/intel_ilp64_parallel_em64t

test -d ./_results/intel_ilp64_parallel_em64t || mkdir -p ./_results/intel_ilp64_parallel_em64t

etc etc...

Did you change environment after sourcing ifortvars.sh?

May be your installation of Intel Fortran Compiler is broken. Try to reinstall it.

Best regards,

Artem

Well, according to the following used path -L../../lib/em64t it means that MKLROOT was not set before run examples

Thanks for the replies guys...I must hang my head in shame !

I was trying the examples under opt and was sourcing the environment script as me and then
using sudo to do the make...DUH!
