Help on how to use included examples on Mac

[CO_Traut]

Hi,

I installed ifort compiler for Mac OS* X which comes with mkl lib. Then I want to test the compiler and mkl lib with an example in the folder/opt/intel/Compiler/11.1/058/Frameworks/mkl/examples/fftw2xf. However, error information shows up as what follows. Could you let me know what's wrong with me?

make lib32

make wrap_lib _IA=32

cd "../.."/interfaces/fftw2xf && make lib32 PRECISION=MKL_DOUBLE compiler=intel INSTALL_DIR=/opt/intel/Compiler/11.1/058/Frameworks/mkl/examples/fftw2xf/lib/32

make clean libfftw2xf_intel.a _IA=32

rm -rf /opt/intel/Compiler/11.1/058/Frameworks/mkl/examples/fftw2xf/lib/32/obj

rm -f /opt/intel/Compiler/11.1/058/Frameworks/mkl/examples/fftw2xf/lib/32/libfftw2xf_intel.a

Hi,

The error shows that you don't have permission to mkdirunder folder"/opt/intel/Compiler/11.1/058/Frameworks/mkl/examples/fftw2xf/lib". So have a check on youraccountaccess permissions for the installation folder and reset the permission if needed.

Thanks much. I changed the permission to the entire folder of /mkl and reran the code. Now I get error msg like this. Seems like 'icc' is required, but I am using ifort instead of icc... I am confused.

From what I see, You try to build wrappers that provide FFTW interface to Intel's own FFT routines. The wrappers are written in C not in Fortran. I do not know much about Mac version, but PC version of MKL, if I remember correctly, comes with precompiled interfaces that you can uses from Fortran programs. Check the manual.

Thanks for your help.

I read through the manual... but I am so confused. The manual command is not consistent with the examples that come with the compiler package.

I'm going to move this discussion to the MKL forum.

Hello CO_Traut,

Yes, as eliosh mentioned, the FFT warpper iswritten by C, so it requiresa C compiler on your machine. the command > make lib32 will invoke Intel C compiler to build the warpper library.But you haven't Intel C Compiler, so build failed.

Attached is one I build. Please copy it into your MKL library library for example,

/opt/intel/Compiler/11.1/058/Frameworks/mkl/lib/32

Then you can use it in the future.

For build the example code under example/fftw2xf,

You may try the command.

for example build real 1d FFT.

and run the executable file,

> _results/intel_parallel_32_lib_double/real_1d_double_ex2.out

Hope it helps
