VS2017编译DirectX11的Effect框架时，出现C2323错误

来源：互联网发布：生活中的帅哥知乎编辑：程序博客网时间：2024/05/29 13:21

d3dxGlobal.h中下列位置出错：

// Custom allocator that uses CDataBlockStore// The trick is that we never free, so we don't have to keep as much state around// Use PRIVATENEW in CEffectLoaderstatic void* __cdecl operator new(size_t s, CDataBlockStore &pAllocator){    D3DXASSERT(s <= 0xffffffff);    return pAllocator.Allocate((UINT)s);}static void __cdecl operator delete(void* p, CDataBlockStore &pAllocator){}

MSDN的解释：

这里写图片描述

与VS的说明是差不多的，是因为新版的VS禁止全局static重载new/delete，只要把static [inline]去掉就可以了；

但是在Effect框架里，new 和delete都是在头文件中定义，是定义不是声明，改完之后框架是能编译通过，但是使用框架的时候会出现链接错误，需要把定义改为声明，然后在Cpp文件中定义:

//**************d3dxGlobal.h*****************// Custom allocator that uses CDataBlockStore// The trick is that we never free, so we don't have to keep as much state around// Use PRIVATENEW in CEffectLoader//static    extern void* __cdecl operator new(size_t s, CDataBlockStore &pAllocator);//static    extern void __cdecl operator delete(void* p, CDataBlockStore &pAllocator);

//**************d3dxGlobal.cpp***********************// Custom allocator that uses CDataBlockStore// The trick is that we never free, so we don't have to keep as much state around// Use PRIVATENEW in CEffectLoader//void* __cdecl operator new(size_t s, CDataBlockStore &pAllocator){    D3DXASSERT(s <= 0xffffffff);    return pAllocator.Allocate((UINT)s);}//void __cdecl operator delete(void* p, CDataBlockStore &pAllocator){}
