Missing FFTW libraries

Leonardo_A_ — Sun, 19 May 2013 17:44:47 GMT

I'm trying to compile a code written in fortran90/95 and I'm getting this error:

Here's the Makefile:

FC = ifort
OPTFC = -O3 -lmpi -L/opt/local/intel/fftw/lib -I/opt/local/intel/fftw/include - I/opt/sgi/mpt/mpt-2.03/include -L/opt/sgi/mpt/mpt-2.03/lib/test : module_param.o incompact3d.o mesure.o schemas.o derive.o spectral.o tools.o poisson.o filtre.o parametre.o slfft3d_shift.o forcage.o navier.o convdiff.o viv.o

$(FC) $(OPTFC) -c slfft3d_shift.f90 viv.o : viv.f90
$(FC) $(OPTFC) -c viv.f90

When I include the libraries required in the Makefile I get the following message:

I'm using ifort compiler and I'm on a supercomputer environment working with MPI. Please, any clue of what is going on? Cheers.

Hi Leonardo,

Hi Leonardo,

could you please make sure the libraries like libsrfftw_mpi.a are in the directory like /opt/intel/fftw/lib?

On the other hand, as i recalled, we add prebuild fftw library in intel fotran compiler. please see http://software.intel.com/en-us/articles/intel-mkl-main-libraries-contain-fftw3-interfaces

And if you build the wrapper library yourself, the libray 's name is like libffw3xf_gnu.a libfftw2xf_intel.a etc. please see some related documetation: http://software.intel.com/en-us/articles/fft-interfaces-in-intelr-mkl

not sure if you are using MKL pre-build FFTW library. Please see the MKL userguide for more information.

Hi Leonardo,

Hi Leonardo,

Add some information for your reference.

There are another similiar question in the forum http://software.intel.com/en-us/forums/topic/301790, the functions are from fftw2xf,

they are not in prebuild mkl library, so if you want to use MKL MPI FFTW2 libarary, you need

first, buid the mpi FFTW wrapper library.

the source code for the wrapper, makefile are located in <mkl dir>\interfacers\fftw2x_cdft, afte enter command like make libia32, you will get library which name is like libfftw2x_cdft_DOUBLE.a . For the build details, please read the mkl manual appendix E.

Then. link mkl library and the wrapper library into your code

the mkl library can be gotten by choose on http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/

for example, the comand line shoud be like

> ifort -L/opt/intel/mkl/lib/ia32 -lfftw2x_cdft_double -mkl=cluster

Hope it helps,

Best Regards,

Ying
