Package: nvidia-cuda-dev
Version: 10.1.105-3+b1
Severity: important

Dear Maintainer,

The NVCC compiler (or rather the nvlink linker) looks for libraries in 
the folder listed in the LIBRARIES environment variable. This 
environment variable is added to from within the nvcc.profile file. In 
Debian/Devuan, that file is located in /etc and contains:

LIBRARIES       =+ $(_SPACE_) -L/usr/lib/x86_64-linux-gnu/stubs

However - that's not the only necessary folder (perhaps not even the 
more important one): nvlink needs to be search /usr/lib/x86_64-linux-gnu 
as well (without the /stubs).

And indeed, if we look at /usr/local/cuda-10.1/bin/nvcc.profile (which 
is also installed for some reason), we find:

LIBRARIES        =+ $(_SPACE_)
"-L$(TOP)/$(_TARGET_DIR_)/lib$(_TARGET_SIZE_)/stubs"
"-L$(TOP)/$(_TARGET_DIR_)/lib$(_TARGET_SIZE_)"

... with both folders.

This is a bug, and it makes nvlink fail to link even simple programs in 
some cases. See, for example:
