Enabling `-std=c++14` flag in Code::Blocks

Question

I have installed Code::Blocks for Windows and want to compile C++14 code like generic lambdas but the binary version of Code::Blocks that I\'ve installed from codeblocks.org

Answer 1

To compile your source code using C++14 in Code::Blocks, you, first of all, need to download and install a compiler that supports C++14 features.

Here’s how you can do it on Windows:

1. Download MinGW from here (particular build) or from official site to choose options
2. Extract it to for example: C:\ (result will be C:\MinGW)
3. Open Code::Blocks
4. Go to Settings => Compiler.
5. Go to “Toolchain Executables”.
6. In the top field “Compiler’s installation directory”, change the directory to the one where you extracted the compiler. E.g C:\MinGW.
7. Change all the necessary files under “Program Files” to match the files under C:\MinGW\bin:

8. Before you hit “OK”, go to the leftmost tab “Compiler settings”.
9. Select “Compiler Flags”.
10. For simplicity, right-click in the list somewhere and select “New Flag”:

11. Type in the following and click "OK", and tick the box of the flag you just created:

12. Lastly, you need to specify the debugger path. Go to "Settings" => "Debugger", click "Default" on the left-hand side and enter the new full path of the executable:

Now, try to compile a program with C++14 features:

#include 
#include 
using namespace std;

auto main() -> int
{
    auto add_two([](auto x, auto y){ return x + y; });

    cout << add_two("I"s, "t"s) << " works!" << endl;
}
