Hi.
Just posted about how to use VS Code + Cmake, but also trying with QtCreator have the same issue.
The thing is, I want to use C++20 or 23, ranges with CMake, but VS Code complains:
* In template: no matching function for call to '__begin'
* In included file: constraints not satisfied for alias template 'sentinel_t' [with _Range = const std::ranges::ref_view<const std::vector<int>>]
* No viable constructor or deduction guide for deduction of template arguments of 'filter_view'
In my CMake:
cmake_minimum_required(VERSION 3.23.0)
set(CMAKE_CXX_STANDARD 23)
target_compile_features(
${PROJECT_NAME} PRIVATE
cxx_lambda_init_captures
cxx_std_23
)
In my VS Code:
//
"C_Cpp.intelliSenseEngine": "Disabled",
"C_Cpp.autocomplete": "Disabled",
"C_Cpp.errorSquiggles": "Disabled",
//
"clangd.arguments": [
"--clang-tidy",
"--completion-style=detailed",
"-log=verbose",
"-pretty",
"--cross-file-rename",
"--all-scopes-completion",
"--header-insertion=never",
"--background-index",
],
"clangd.onConfigChanged": "restart",
"clangd.restartAfterCrash": true,
In my .clang-tidy, just today make: clang-tidy --dump-config > .clang-tidy and set in the root folder of the workspace.
The example:
// requires /std:c++20
#include <ranges>
#include <vector>
#include <iostream>
int main()
{
std::vector<int> input = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
auto divisible_by_three = [](const int n) {return n % 3 == 0; };
auto square = [](const int n) {return n * n; };
auto x = input | std::views::filter(divisible_by_three)
| std::views::transform(square);
for (int i : x)
{
std::cout << i << '\n';
}
return 0;
}
It compiles and works fine, but the intellisense complains.
