[Rtk-users] building CUDA

[Howard]

When I did the following:

CUDA_HAVE_GPU  ON
CUDA_BUILD_CUBIN OFF ( this removed the errors I reported in last posting)
CUDA_HOST_COMPILATION_CPP ON (following Yang K Park's screenshot)

building was successful. I could run

rtkfdk --hardware cuda -r ... ((Is this the correct way of running fdk
using cuda?)

with successful reconstruction. It's done in < 15s, wow!

A separate question: how to specify cuda for rtksart,
rtkadmmwavelets, rtkadmmtotalvariations etc?

Thanks,
-howard
