Build error on Ubuntu 19 and CUDA 10

[Dr Aarij Mahmood Hussaan]

Hye all

I am on Ubuntu 19 and using CUDA 10, but cannot seem to build caffe from source due to some undefined reference to cuda objects

any pointers?

Most likely, your CUDA installation is incomplete.

Do you have a file in /etc/ld.so.conf.d/ named cuda.conf or thereabouts?
