Редактировать : я опубликовал проблему на GitHub range-v3
Итак, я пытаюсь использовать библиотеку range-v3. Но когда я компилирую свой код, он останавливается с ошибкой C7608. Вот соответствующий фрагмент:
#include "json/single_include/nlohmann/json.hpp"
#include "range-v3/include/range/v3/all.hpp"
class myClass
{
private:
nlohmann::json json_;
public:
auto getJSON() const { return json_; }
};
int main()
{
std::map<int, myClass> patterns_;
auto getJSON = [](const auto &item) { return item.getJSON(); }; //Returns a nlohmann::json
namespace rv = ranges::views;
std::vector<nlohmann::json> jsons = patterns_ | rv::values | rv::transform(getJSON)
| ranges::to_vector;
return 0;
}
Вывод компилятора:
