I've resolved many errors, but have one that I'm hung up on now. It seems that there is no MKL wrapper for 'rfftwnd_create_plan_specific', as I get this error (just a snippet):<BR /><BR />obj/ComputePme.o: In function `ComputePmeMgr::initialize(CkQdMsg*)':ComputePme.C:(.text+0x260e): undefined reference to `rfftwnd_create_plan_specific'<BR />:ComputePme.C:(.text+0x2779): undefined reference to `rfftwnd_create_plan_specific'<BR />obj/SimParameters.o: In function `SimParameters::print_config(ParseOptions&amp;, ConfigList*, char*&amp;)':SimParameters.C:(.text+0x8381): undefined reference to `rfftwnd_create_plan_specific'<BR />:SimParameters.C:(.text+0x855a): undefined reference to `rfftwnd_create_plan_specific'<BR />collect2: ld returned 1 exit status<BR />Fatal Error by charmc in directory /home/jake/Builds/NAMD_2.6_Source/Linux-amd64-g++<BR /><BR />This then causes make to fail. Does anyone know a workaround for this? I'm not very familiar with FFTW's innards.<BR /><BR />Thanks in advance,<BR /><BR />Jake<BR /><BR /> Thu, 05 Oct 2006 08:26:55 GMT jake_michaelson 2006-10-05T08:26:55Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/FFTW-rfftwnd-create-plan-specific-wrapper-missing-in-MKL-8-1-1/m-p/907646#M11860 Hi all,<BR /><BR />I'm trying to compile NAMD, which relies on FFTW 2.x, with the MKL wrapper library for FFTW 2.
