I got the above error when i try to build my project which contains relocatable device code.
Till-now, when i use the device code in one file i.e. kernel.cu, building went just fine. Now i had a function which is used by both the device and host, so i modified that function with a prefix host device and passed -dc flag to nvcc.
When i tried building the project using Cmake/make, it shows the following
/usr/local/bin/cmake -E cmake_link_script CMakeFiles/test_zip1_gpu.dir/dlink.txt --verbose=1
