Problems on .so file

[guanhuaw]

Hi~
I try to install this on Ubuntu 16.04，but always meet with this problem when running demo:

Error in gpuNUFFT (line 104)

Error in cgsense_phantom_recon (line 34)
FT = gpuNUFFT(k',col(w(:,:,1)),osf,wg,sw,[N,N,nSl],[],true);

And I've tried cuda7.5/9.0/9.1. When compiling, this always happens

Basically I follow the tutorial on the video, and I dont know where the problem comes from. Thanks a lot!

Hi, I'm sorry for coming back late - are you still having issues?

The missing symbols are likely MATLAB/gcc related. Check the gcc compatibility recommendations with your version of MATLAB.
The warnings do not seem to be an issue and come up even in a working build.
It should build with Cuda 9.1, Ubuntu 16.04 (latest updates and default gcc) and MATLAB R2018b. Ironically MATLAB wants gcc 6.3 (non-standard for Ubuntu) but works with 5.4 at least for gpuNUFFT and some other in-house mexa64 builds.
