Cuda compile error visual studio 2015

[sorheimen]

I have problems getting the solver_cuda project to compile, I am using cuda 9.1 and VS 2015, seems to be something with nvcc not handling c++ files correctly, error output:

Any clues to a fix to this problem? The ordinary solver c++ project compiles and build just fine!

The error seems to be coming from a boost header. I don't have access to a Windows machine with CUDA, but solver_cuda does compile on linux with CUDA 9.1 and boost-1.66. I don't see any problems at the line the error references:

https://github.com/boostorg/preprocessor/blob/56090c56b5c78418b6dbe8c3c2ba576395152f83/include/boost/preprocessor/slot/detail/shared.hpp#L27

Specifically, I don't see where an unmatched parenthesis could come from. So, could this be an nvcc bug or a faulty boost installation?

I faced this too. It's hard to understand why it happens...

[ddemidov]

I don't have the means to reproduce this, but it looks like it is an issue with nvcc and boost, similar to this stackoverflow question:
https://stackoverflow.com/questions/50877647/thrustboost-code-compilation-error

Since recently, amgcl does only require boost for the runtime interface, and even then, it only depends on the Boost.property_tree library. I've just checked, and it looks like boost/preprocessor/slot/detail/shared.hpp is never included (directly or indirectly) into solver_cuda. Can you retry with the master branch of amgcl?

[ddemidov]

Correction: boost/preprocessor/slot/detail/shared.hpp is still included when runtime interface is used. But it should be possible to go completely boost-free with compile-time interface.

Hi Denis,

I ran into the same issue, and it is compiling with VS2019 and c++14

Not sure if anyone could solve this

[mobereng]

Is there any way to go boost free on .cu files ?, so it can compile great, I can have another file with .cpp extension and it won't cause any problems

I'm currently testing

typedef amgcl::backend::cuda<double> Backend;
typedef amgcl::make_solver<
        amgcl::amg<
          Backend,
          amgcl::coarsening::smoothed_aggregation,
          amgcl::relaxation::ilu0
        >,
        amgcl::solver::bicgstab<Backend>
        > Solver;

[ddemidov]

Boost is used in examples/solver.cpp (which is linked to solver.cu and compiled as cuda source here).

Can you try and compile the amgcl examples using the provided cmake files?

To go Boost-free you need to define AMGCL_NO_BOOST and stick to the compile-time interface.

[mobereng]

For sure, let me test and come back

[mobereng]

The issue was solved on the last version for development branch for boost preprocessor. Refer to the follogin ticket if anyone still stuck on the same compilation problem Boost preprocessor issue 37

Thanks for the help. I think this one can be closed @ddemidov
