The newest version of Visual Studio C++ compiler broke our code. Our application uses STL algorithm like std::minmax_element on measured samples. Sometimes the devices do not deliver a valid sample and a NaN element is inserted instead. Up to now…
I'm writing a C++ program for a 2D RPG game, using the SDL2 libraries. I have a class named Entity that has a property named worldY: class Entity { public: ... // coordinate mondo: la mappa del mondo int worldX…
I've used C++17 in VS Code. Now I want to use C++20 or C++23, but I can't change from the C++17 version. I've tried many ways, like adding "-std-c++2b" in Task.json or setting C++Standard to C++23, but my VS Code…
I want to have X amount of std::vectors of equal size, which I can be processed together in a for loop which goes from start to finish in a linear fashion. For example: for (int i = 0; i <…
I'm using std::variant to specify the types of properties that an entity in my project may have, and stumbled upon this code from cppreference: std::visit([](auto&& arg) { using T = std::decay_t<decltype(arg)>; if constexpr (std::is_same_v<T, int>) std::cout << "int with value…
I have a problem while defining a template class containing T. namespace { template <typename T1, typename T2 = T1, typename Test = bool> struct is_comparable : std::integral_constant<bool, false> {}; template <typename T1, typename T2> struct is_comparable<T1, T2, decltype(std::declval<const std::decay_t<T1>>()…

I'm running macOS Monterey 12.6.1 on a Macbook Air and there are no further updates available. I checked my AppleClang version and it's 14.0.0. If I compile a simple C++ code using e.g. std::boyer_moore_searcher, the function is not found like…
Consider below scenario: Thread 1 mutexLk1_ gcondVar_.wait(mutexLk1); Thread 2 mutexLk2_ gcondVar_.wait(mutexLk2); Thread 3 condVar_ gcondVar_.notify_all(); What I observe is that notify_all() does not wake up both the threads but just one on the two. If i were to replace mutexLk2…
I am trying to compile a C++17 code with g++-9 that uses execution policy in Ubuntu 18.04.5 LTS. I build and installed TBB 2020.2 with GCC-9 manually as it is not available by default for Ubuntu 18. When I call…
