0xc000007b Erreur - mais toutes les DLL sont en 32 bits

Question

Je compile mon code C++ avec l'option /clr en utilisant Visual Studio 2008 sur Windows 7 32 bit OS ciblant .NET Framework 3.5.

Toutes les DLL sont en 32 bits (vérifié avec Dependency Walker).

D'après mes recherches, cette erreur survient lorsque du code 32 bits appelle des DLL 64 bits, ce qui n'est pas le cas ici.

Existe-t-il d'autres causes principales de l'erreur 0xc000007b ?

Answer 1

Ce problème vient d'être résolu. Il semble que cette erreur soit non seulement Les problèmes sont causés par le mélange de bibliothèques 64 bits dans un code 32 bits, mais aussi lorsque les bibliothèques sont mal conçues - dans mon cas, j'utilisais une bibliothèque PCRE binaire.

J'ai construit PCRE moi-même en utilisant MingW et maintenant tout fonctionne bien.

Pour utiliser .NET FW 4.0, vous devez utiliser le code shim d'activation hérité pour charger .NET FW en tant que composant COM dans votre application d'hébergement. dans votre application d'hébergement, comme ceci :

Utiliser une macro

#define LEGACY_ACTIVATION_SHIM_ALLOW_LEGACY_API_FALLBACK

Sudoku.Runtime.h :

#pragma once
// 
extern "C" int wWinMainCRTStartup();

Sudoku.Runtime.cpp :

// Sudoku.Runtime.cpp : Defines the entry point for the application.
//

#include "stdafx.h"

int _runtime()
{
    wWinMainCRTStartup();
    return 0;
}

int APIENTRY _tWinMain(HINSTANCE, HINSTANCE, LPTSTR, int)
{
    try
