0xc000007b Error - but all DLLs are 32 bit
提问by user375868
I am compiling my C++ code with /clr option using Visual Studio 2008 on Windows 7 32 bit OS targeting .NET Framework 3.5.
我正在使用 Visual Studio 2008 在面向 .NET Framework 3.5 的 Windows 7 32 位操作系统上使用 /clr 选项编译我的 C++ 代码。
All the DLLs are 32 bit (verified using Dependency Walker).
所有 DLL 都是 32 位的（使用 Dependency Walker 验证）。
As per my research this error comes up when 32 bit code calls 64 bit DLLs but this not the case here.
根据我的研究，当 32 位代码调用 64 位 DLL 时会出现此错误，但此处并非如此。
Are there any other root causes of error 0xc000007b?
错误 0xc000007b 是否还有其他根本原因？

Just happened to resolve this issue. It seems that this error is not onlycaused by mixing 64 bit libraries in 32 bit code but also when libraries are messed up - in my case I was using binary PCRE library.
刚好解决了这个问题。似乎这个错误不仅是由于在 32 位代码中混合了 64 位库引起的，而且是由于库混乱造成的——在我的情况下，我使用的是二进制 PCRE 库。
I built PCRE myself using MingW and now everything works fine.
我自己使用 MingW 构建了 PCRE，现在一切正常。

For use .NET FW 4.0, you should use legacy activation shim code to load .NET FW as COM component into your hosting app, like this:
要使用 .NET FW 4.0，您应该使用旧版激活填充代码将 .NET FW 作为 COM 组件加载到您的托管应用程序中，如下所示：
Use macro
使用宏

// This file allows simple migration from .NET Runtime v2 Host Activation APIs

// For example,
// #include "mscoree.h"

// CorBindToRuntimeEx(

// To enable fallback to the legacy APIs when v4.0 is not installed on the machine,
// define LEGACY_ACTIVATION_SHIM_ALLOW_LEGACY_API_FALLBACK before including this

// To use the legacy API fallback in a delay-loaded fashion, include LegacyActivationShimDelayLoad.h
