Hi,

The binary expects the 5.0 library files, it means it was compiled with ver 5 of the CUDA Toolkit. You need to download and install the 5.0 Toolkit and then set your cuda_home env variable accordingly.

Best regards,

hi freesufer folks, has your new version 6 run a successful cuda7.5 gpu on ubuntu 16.04? i'm getting a core dump. jeff here is the cmd:

recon-all -all -use-gpu -s ${filenames_arr[$i]}_freesurf -i ${sesnum_arr[$i]}/anat/${filenames_arr[$i]}.nii

first output gave:

thinking its a missing link i did: sudo ln -s /usr/lib/x86_64-linux-gnu/libcudart.so.7.5.18 /usr/lib/x86_64-linux-gnu/libcudart.so.5.0

and then got:
