Configuring C++17 supported compiler on wnidows for CodeBlocks and Visual Studio Code

youtube视频教程：

1. install mingw-64 on windows

1.1 download mingw-64

goto download link to download the install program: mingw-w64-install

or download the mingW version x86_64-win32-seh

1.2 extracted the 7z compressed file to a foler using 7z

1.3 add the bin folder of mingw-64 to Windows PATH environment variable.

open a new Command Prompt and type:

g++ --version
gdb --version

1.4 compile and run a c++ program

use notepad++ or notepad to edit a file “hello.cpp” as following:

#include <array>
#include <iostream>
#include <string_view>
#include <tuple>
#include <type_traits>
 
namespace a::b::c
{
    inline constexpr std::string_view str{ "hello" };
}
 
template <class... T>
std::tuple<std::size_t, std::common_type_t<T...>> sum(T... args)
{
    return { sizeof...(T), (args + ...) };
}
 
int main()
{
    auto [iNumbers, iSum]{ sum(1, 2, 3) };
    std::cout << a::b::c::str << ' ' << iNumbers << ' ' << iSum << '\n';
 
    std::array arr{ 1, 2, 3 };
 
    std::cout << std::size(arr) << '\n';
 
    return 0;
}

in new Command Prompt and type:

g++ -std==c++17 hello.cpp -o hello.exe
hello.exe

2. cofigure CodeBlocks for mingW-64 C++ compiler

CodeBlocks

from the main menu to select “Settings → Compiler →Toolchain executables.

change from

from the main menu to select “Settings → Compiler →compiler setting. click the “compiler flag” and check the box “Have g++ follow the coming -std=c++1z (aka C++17) ISO C++ language standard…”

Alternatively, you can go to the Other Compiler Options tab and type in -std=c++17.
