Einstein@home libclfft example error

[truboxl]

So I started to try and see if I can port BOINC project Einstein@home binary radio pulsar search application to run on clvk (perhaps on embedded devices).
https://einsteinathome.org/application-source-code-and-license
https://einsteinathome.org/brp-src-release.zip

One of the dependencies is libclfft

However there seems to be an issue with example program when execute with clvk.
The program does not output strings of numbers but only output clFFT_execute.

I have tried different vendor of Vulkan drivers but they all failing the same error.

Steps are roughly:

git clone --depth 1 https://gitlab.aei.uni-hannover.de/einsteinathome/libclfft
cd libclfft/example
make
./clfft_example test.single
./clfft_example test.multi
