MSVS 2010 - C Programm mit vielen Imports

MrSpider · Jun 15, 2011

Hallo,

Ich habe in MSVS 2010 ein C-Programm kompiliert, welches aber nach dem Compilen jede Menge Funktionen in der IAT hat, welche ich gar nicht benutze.

Auch nach längerem Suchen habe ich keine Option gefunden, mit welcher man die zuätzlichen Imports entfernen kann.

Konkret hat die exe folgende Imports:

Code:

function GetProcAddress(hModule: HMODULE; lpProcName: LPCSTR): FARPROC;
      stdcall; external 'kernel32.dll' name 'GetProcAddress' index 340;

Die einzigen Funktionen, die ich in meinem Code nutze sind die ersten drei. Wie bekomme ich nun die restlichen Imports weg ?

Geht nicht. Wird größtenteils für Initcode vom Compiler gebraucht.
