miniexe

A way to creating small executables with Microsoft Visual Studio,without import directory,remove the c run time library initialization code,but can dynamic call C standard library from msvcrt.dll.

All windows api and c api dynamic load from dll,include Loadlibrary,so we can building a exe without import directory.

1，how to work?

1,get kernel32.dll base from PEB
        |
        |
2,get LoadLibraryA,... api address from kernel32.dll base
        |
        |
3,load user32.dll and msvcrt.dll
        |
        |
4,get others api by loaded mod's export table
        |
        |
5,spec our entry point,do not link default c run time(/NODEFAULTLIB)

2,how to spec entry point?

realize mainCRTstartup function,by miniCRT

3,how to build?

First install cmake, git clone ...
cd .../src
mkdir build
cmake ../
vs2017 build release

On my pc,size of exe only 2560Bytes(2.5KB),it could be smaller, no run time dependence,all dlls are windows original.
