BUILD clFFT on ROCM stack

You can build and run clFFT on ROCM software stack.

Install OpenCL on ROCM:

sudo apt-get install rocm opencl-rocm-dev

You will get a folder /opt/rocm/opencl.

Setup

setting environment variable is recommended export OPENCL_ROOT=/opt/rocm/opencl

On the cmake-gui or ccmake, point "OPENCL_INCLUDE_DIRS" to "/opt/rocm/opencl" & "OPENCL_LIBRARIES" to "/opt/rocm/opencl/lib/x86_64/libOpenCL.so"

Add your build clFFT.so into environment variable. On my machine it is like: export LD_LIBRARY_PATH=~/FFT/clFFT_BUILD/library/:${LD_LIBRARY_PATH}

• the other settings are exactly the same as posted in other sections

Know Issue:

• libStatTimer.so: cannot open shared object file: No such file or directory Could not find the external timing library; timings disabled

Solution: this library is build by clFFT, too. Copy from ${MY_CLFFT_BUILD_DIR}/StatTimer/ and paste it into this same directory as your executable.
