I'm using the MKL version distributed with composer_xe_2013.1.117 for Linux, and I cannot link to the F77 interface to FFTW. The functions I'm looking for are documented here: http://software.intel.com/sites/products/documentation/doclib/stdxe/2013... but none of the references to the f77 functions can be resolved. For example:
FFT.f90:(.text+0x799): undefined reference to `rfftw_f77_create_plan_'
The fftw_f77 functions seem to be missing entirely:
> nm * | grep -i fftw | grep -i f77
000000000012f770 T fftw_plan_dft_c2r_1d
000000000012f770 T fftw_execute_split_dft_c2r
Should I look for these functions in a different directory? Please help.
