error while installing p3dfft library

[p-awasthi]

I am having issues while installing p3dfft++ library. I have fftw (mpi enabled) library installed at location /usr/local/FFTW. I am trying to install p3dfft++ library after downloading the source file from official git hub page. When I install using the following command (./configure --prefix=/usr/local/p3dfft --enable-gnu --enable-fftw --with-fftw=/usr/local/FFTW FC=mpif90 CC=mpicc CXX=mpicxx), I am getting the following error after executing make file.

(Rank mismatch between actual argument at (1) and actual argument at (2) (scalar and rank-1)
make[3]: *** [Makefile:460: test1D_cos.o] Error 1
make[3]: Leaving directory '/home/pratyush/Downloads/p3dfft.3-v.3.1.2/sample/FORTRAN'
make[2]: *** [Makefile:315: all-recursive] Error 1
make[2]: Leaving directory '/home/pratyush/Downloads/p3dfft.3-v.3.1.2/sample'
make[1]: *** [Makefile:412: all-recursive] Error 1
make[1]: Leaving directory '/home/pratyush/Downloads/p3dfft.3-v.3.1.2'
make: *** [Makefile:331: all] Error 2)

After exploring on internet, I found that adding FCFLAG suppresses the error to warning. Now executing the command (./configure --prefix=/usr/local/p3dfft --enable-gnu --enable-fftw --with-fftw=/usr/local/FFTW FC=mpif90 CC=mpicc CXX=mpicxx FCFLAGS="-fallow-argument-mismatch"). This installs the library in the system. But when I run the sample files as provided I got a DEF_FFT_FLAGS error to which I defined DEF_FFT_FLAGS as 123. Now when I am executing the sample file provided I am getting the following error.

I have also tried installing the previous version but errors remain the same.
Any help is appreciated.
Thanks and regards

Hi, You want to make sure you link with both -lfftw and -lfftwf Hope this helps. Dmitry

Hey @dmitrypek
mpicxx -o check check.cpp -I/usr/local/FFTW/include -L/usr/local/FFTW/lib -lfftw3 -I/usr/local/p3dfft/include -L/usr/local/p3dfft/lib -lp3dfft -lm
This is how i am running my code file named check. FFTW and p3dfft is the folder in root where FFTW and P3dfft++ is installed. Isn't linking lfftw3 link fftw in float as well as double precision?

Hey @dmitrypek
mpicxx -o check check.cpp -I/usr/local/FFTW/include -L/usr/local/FFTW/lib -lfftw3 -lfftw3f -I/usr/local/p3dfft/include -L/usr/local/p3dfft/lib -lp3dfft.3 -lm
Linking the -lfftw3f explicitly did not resolve the issue. I get the same error.
I also tried exporting the FFTW path to $LD_LIBRARY_PATH using
export LD_LIBRARY_PATH=/usr/local/FFTW/include:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/local/FFTW/lib:$LD_LIBRARY_PATH

Is there an issue with DEF_FFT_FLAGS which I have defined as 123?
