How to reduce the size of the executable file after compilation in CodeBlocks.

(1/2) > >>

XiloManX:
I started to learn C + +. I use CodeBlocks in Windows. I noticed that after compilation, is a file size of 467kB (release) and 943kB (debug).But the executable should be much less.

So I have two questions:
1. Why is it so big?
2. How to reduce the binary to the minimum size.

A simple example that when compiled in CodeBlocks get enormous size.

--- Code: ---#include <iostream>

using namespace std;

int main()
{
    cout << "Hello world!" << endl;
    return 0;
}

--- End code ---

There are some options listed here.  Keep in mind that many compiler flags can have other effects (for example, static vs. dynamic runtime libraries), so read documentation to understand what they do.  If something does not make sense, try Google (it does not bite).

Did everything as written, but does not collect CodeBlocks project. What is wrong? Build log is attached (Code::Blocks v12.11).

You can also use an external pgm in Post build steps.

Google "upx"

Thank you. But I'm more interested in the question of why is not going to my project. What's the error and how to fix it?
