Pkg.build("CUDArt")? Any error messages that it emits?
from cudart.jl.

It's very strange that it seems to be there. I wonder if the file is corrupted or something.

This seems likely to be an OS or julia error. Assuming you're on linux, does readelf do the expected things on libwrapcuda.so? What's versioninfo()? Are there other packages that use C code that give you problems?
This is not my strong suit, so if a little more poking around doesn't resolve the problem, you might be better off filing a julia issue. Sorry not to be more helpful.

I got this problem and solved it by simply re-install the package... @AStupidBear

What if you go into the deps directory and touch wrapcuda.c; make?

@timholy It works. But

That failure is relevant only if (1) you have multiple CUDA devices on the same machine, and (2) want to use multiple julia workers to synchronize work among the devices. Unless both of those apply to you, you should be good to go.
(Fixes for the error would of course be gratefully accepted, but it's hard for me to debug since that test works for me.)
