An error occurs upon compilation using VS22 community edition in vector.hpp.

Boost Version: 1.81
Platform: Windows 10 64x

This uses Thrust functionality to calculate a large amount of ODEs.

What is wrong and can i fix it on my end?

[RKGalaxy-Luo]

I've tried such a method:
correct the code in "boost\fusion\container\vector\vector.hpp"

private:
template <std::size_t J>
using store_at = decltype(store_at_impl(static_cast<vector_data*>(nullptr)));

public:
template <std::size_t J>
BOOST_CXX14_CONSTEXPR BOOST_FUSION_GPU_ENABLED
typename store_at::elem_type& at_impl(std::integral_constant<std::size_t, J>)
{
return store_at::elem;
}

template <std::size_t J>
BOOST_CONSTEXPR BOOST_FUSION_GPU_ENABLED
typename store_at<J>::elem_type const& at_impl(std::integral_constant<std::size_t, J>) const
{
    return store_at<J>::elem;
}

};

NOTICE: I don't know whether such a method will have an influence on other libraries

If you think this is a fusion issue, please post an MVCE (without any dependencies). I have no expertise on the other dependent libraries.

[lingyuanmoshang]

Has this issue been solved？

Has this issue been solved？

Again, please post an MVCE https://stackoverflow.com/help/minimal-reproducible-example

Hello,
I have been facing the same issue then I am going to include a MVCE using a .cu file:

Configurations:
-Microsoft Visual Studio Community 2022 (64-bit) - Current
Version 17.11.0
-Nvidia Driver Version: 560.81
-CUDA Toolkit 12.6
-BOOST 1.86
-MVCE.cu

MVCE.cu:

#include <boost/numeric/odeint.hpp>
int main()
{

}

Output:

1. Error C2334 unexpected token(s) preceding '{'; skipping apparent function body CudaRuntime1 C:\Users\benny\Downloads\boost_1_86_0\boost\fusion\container\vector\vector.hpp 246

3. Error C2062 type 'unknown-type' unexpected CudaRuntime1 C:\Users\benny\Downloads\boost_1_86_0\boost\fusion\container\vector\vector.hpp 236

7.Error C2062 type 'unknown-type' unexpected CudaRuntime1 C:\Users\benny\Downloads\boost_1_86_0\boost\fusion\container\vector\vector.hpp 243

The first error refers to the use of a C++ version prior to C++ 20 but I have used C++ 20 and it is the same error.

On the other hand, if it is replaced odeint by interval then the code compiles properly.

#include <boost/numeric/odeint.hpp>
int main()
{

}

Output:
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
========== Build completed at 11:07 AM and took 01.917 seconds ==========

Finally, this code works properly in Ubuntu using CMake then it is not a general incompatibility between CUDA and BOOST. I hope you can help us with this issue. Thank you so much in advance! Let me know if there is something I can do to help you to fix this error.

#include <boost/numeric/odeint.hpp>

This is not directly a Boost.Fusion issue, and should probably be redirected to Boost.Numeric.Odeint instead.

Hello:
On Windows 11, I have found that if you comment out these lines from vector.hpp the code works properly. In my case, I am using the Boost library in the host then I do not need anything in the device. Definitely, there are some differences in how vector.hpp is treated on Windows and Ubuntu.

Code using C++ compiler:

#include <boost/numeric/odeint.hpp>
#include <iostream>
#include <vector>

using namespace boost::numeric::odeint;

std::vector<std::vector<double>> variable;
std::vector<double> times;

void system_of_equations(const std::vector<double>& variables,
	std::vector<double>& derivative_rates, const double time)
{
	derivative_rates[0] = variables[0] + variables[1];
	derivative_rates[1] = variables[0] - variables[1];
}

void printVariables(const std::vector<double>& variables, const double time)
{
	std::cout << "t=" << time << "   "
		<< "x=" << variables[0] << "   "
		<< "y=" << variables[1] << std::endl;

	variable.push_back(variables);
	times.push_back(time);
}

int main()
{
	std::vector<double> initial_variables = { 1.0, 0.0 }; 

	double start_time = 0.0, end_time = 5,
		time_step = 1e-4; 
	integrate(system_of_equations, initial_variables, start_time, end_time, time_step, printVariables);

	return 0;
}
