CUDA nvcc compilation error

[Char-Aznable]

Hi, I got this very simple Taocpp code:

#include <iostream>
#include <tao/tuple/tuple.hpp>

int main(int argc, char* argv[]) {
   
  auto t2 = tao::tuple< int, double, int >( 1, 2, 3 );

  
  tao::get< 0 >( t2 ) = 0;
  tao::get< 1 >( t2 ) = 2;
  tao::get< 2 >( t2 ) = 3;

}

with the dependency: https://github.com/taocpp/tuple.git cloned to ./_deps/taotuple-src. Then I compile it with nvcc 11.4.48 and g++ 9.3.0 by

nvcc -ccbin g++-9 -I_deps/taotuple-src/include -x cu testTuple.cpp -o testTuple

and get this compilation error:

testTuple.cpp(19): error: no instance of overloaded function "tao::get" matches the argument list
            argument types are: (tao::tuple<int, double, int>)

testTuple.cpp(20): error: no instance of overloaded function "tao::get" matches the argument list
            argument types are: (tao::tuple<int, double, int>)

testTuple.cpp(21): error: no instance of overloaded function "tao::get" matches the argument list
            argument types are: (tao::tuple<int, double, int>)

I am using a5f3b87 on the main branch.

Since I'm not using CUDA myself, there isn't much that I can do. You could try to update to the latest commit, see if that helps. Or maybe @allisonvacanti might help? She developed the original PR for CUDA support. Allison: Let me know if it is OK for you if I tag you when CUDA-related issues with taocpp/tuple come up. If not, I will stop doing so.

The problem persists in the latest commit a5f3b87

@d-frey It appears maybe somebody fixed it in this fork?:

@Char-Aznable Could you send the complete output from the compiler, please?

[d-frey]

@DarthRubik That is #6, where I hoped that my patch also fixed the issue. Apparently that is not the case, so I'll see what I can do. Can you also reproduce the error? If so, I'd like to know which version of GCC, nvcc, etc. you are using and also the complete error message from the compiler with all the details (candidates, why rejected, etc.)

[DarthRubik]

@d-frey I do not have a CUDA environment set up and I cannot reproduce the error

Could you send the complete output from the compiler, please?

Those I posted were all I got from it
