Remove Unused Imports from Import Table
« on: March 25, 2019, 09:26:05 pm »
Hi Everybody

I'm working with Visual Studio 2012 & 2017 with C++ 11 and Pelles C 9.0 with C++ 11...

When I build a empty program and DLL but they contain lots of unused imports in pe file!

VC++ has 26 imports of KERNEL32 and Pelles has 55 imports of KERNEL32 My project is totally empty!

I need to remove them from linker and compiled file.

I have an DLL is compiled with Pelles C and it only has 4 import that it really use :

Code: [Select]
          VirtualProtect  ord:0 rva2iat: 000012A0
          GetModuleHandleA  ord:0 rva2iat: 000012A8
          Sleep  ord:0 rva2iat: 000012B0
          CreateThread  ord:0 rva2iat: 000012B8

I want to do the same , I don't need any of those 55 imports and functions , How Can I do it ?

< Referenced File developed in Pelles C Attached >

Examine this:
Code: [Select]
#include <windows.h>

#ifdef _WIN64
#pragma comment(linker, "/ENTRY:DllMainCRTStartup")
#pragma comment(linker, "/ENTRY:_DllMainCRTStartup@12")
BOOL WINAPI DllMainCRTStartup(HANDLE hDLL, DWORD dwReason, LPVOID lpReserved)
if (dwReason == DLL_PROCESS_ATTACH) g_hmod = hDLL;
return TRUE;
May the source be with you
