Lowering build size | 易学教程

问题

Is there any way I can lower my build size when I am using static linking for the C++ runtime libraries in VS2013?

My original file was just 15kb, but I couldn't run it on my other computers without a missing .dll message popping up. I decided to use static linking and now the size is ~100kb.

I am using the Windows.h header and WinAPI functions.

If you're only going to display a MessageBox, you don't need to link to any static libraries.

#include <windows.h>

void entry(void) {    
    MessageBox(NULL, "Hello, World!", "", MB_OK);
    ExitProcess(0);
}

Compile and link using VC++2013, with the following command line:

cl /O1 /GS- hello32.c /link /nodefaultlib /entry:entry /subsystem:windows user32.lib kernel32.lib

At least for me (with VC++ 2013) that produces an executable of 2560 bytes (that depends only on core Windows DLLs, so it shouldn't require anything extra to run on even the most bare-bones system).

回答2:

As your main intention is to keep size in control, dll is way to go.

As far as your missing dll is concerned it can be addressed. If you are using standard libary missing error then its good idea to install redistributable on machine where you are running application.

Redistributable for VS2013

If you don't use MFC etc. you can

#define WIN32_LEAN_AND_MEAN
#include <Windows.h>

to reduce size of your code
