I get the following error after installation then import of the gpyfft module:

ImportError: /home/amorgan/local/lib/python27/site-packages/gpyfft-022-py27-linux-x86_64egg/gpyfft/gpyfftlibso: undefined symbol: clfftSetPlanCallback

clfftSetPlanCallback has been recently added to clFFT, probably the prebuilt binaries you are using haven’t been updated. Building them yourself is not a big issue, then you will also profit from improved performance. Alternatively, checkout an older version of gpyfft.

Details:

I am trying to get gpyfft fired up on a gpu cluster for work (running under linux sl6) To this end I am testing at home under Ubuntu with a Haswell HD GPU installing as a 'user' with no root privileges Anyway:
I downloaded the clFFT prebuilt binaries at /home/amorgan/Physics/2016/pyopencl/clFFT-Full-2100-Linux-x64/

$ git clone https://githubcom/geggo/gpyfftgit
$ cd gpyfft
$ export LDFLAGS="-L/home/amorgan/Physics/2016/pyopencl/clFFT-Full-2100-Linux-x64/lib64 "

Then I set:

CLFFT_DIR = r'/home/amorgan/Physics/2016/pyopencl/clFFT-Full-2100-Linux-x64'
CL_INCL_DIRS = ['/home/amorgan/Physics/2016/pyopencl/clFFT-Full-2100-Linux-x64/include']

in setuppy

$ python setuppy build

This works with a single warning:

/home/amorgan/Physics/2016/pyopencl/clFFT-Full-2100-Linux-x64/include/clFFTh:257:2: warning: function declaration isn’t a prototype [-Wstrict-prototypes]
CLFFTAPI clfftStatus clfftTeardown( );

Instillation works with no warnings:

$ python setuppy install --user
$ cd ~
$ ipython

In [1]: import gpyfft
