C++"void __cdecl operator delete(void *)"原因

VC缺省链接库的顺序不对导致链接错误error LNK2005: "void __cdecl operator delete(void *)"(??3@YAXPAX@Z) already defined in libcpmt.lib(delop.obj)

在编译工程Uasp时,MFC static Library和Code Generation/MultiThread选项时,链接总出现问题:

nafxcw.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *)" ( ??3@YAXPAX@Z) already defined in libcpmt.lib(delop.obj)
nafxcw.lib(afxmem.obj) : warning LNK4006: "void __cdecl operator delete(void *)" ( ??3@YAXPAX@Z) already defined in libcpmt.lib(delop.obj); second definition ignored

我个人的设置是这样的,跟网上的有点不一样(顺序不同)

1.

project setting ---gategory --input ---ignorelibries 下面添加要忽略的那两个库本例为

nafxcw.lib libcpmt.lib

2.修改连接库的顺序

project setting ---gategory --general ---object/library modules:

添加  Libcmtd.lib Nafxcwd.lib  (这两个lib顺序不一样,如果还是不行  就改成

Nafxcwd.lib  Libcmtd.lib )

3、添加链接库

工程-设置-连接-常规

对象/库模块：

Nafxcwd.lib  Libcmtd.lib  （注意这两个库的顺序）
