Type of Bug

Compile-time Error

Component

CUB

Describe the bug

Multiple definition error from 4678853 needs a reproducer added to our test suite. This should be as simple as linking together a pair of each header. We should probably try to do this in every project if not already done.

How to Reproduce

create bar.cc
#include <thrust/complex.h>

create foo.cc
#include <thrust/complex.h>

build:
g++ -c -fPIC -I /usr/local/cuda/include bar.cc
g++ -c -fPIC -I /usr/local/cuda/include foo.cc
g++ -fPIC bar.o foo.o -shared -Wl,-soname,libhello.so -o libhello.so

Expected behavior

We shouldn't emit multiple definition errors by leaking non-static interfaces into the TU.

I believe we should do that in the context of our all public headers test set.

We already have all public headers there and it should be simple to create two TUs that include all those headers and link two.

Exactly. We just need to flex that we can link all the permutations of NVCC + compiler.

e.g.
NVCC+NVCC
GCC+NVCC
GCC+GCC.
