error LNK2005 (把sqlite3.c加到vs2010 x64project中碰到的問題)

一開始的error是要拿掉precompile header
拿掉之後跑出

Error 1 error LNK2005: "void * __cdecl operator new(unsigned __int64)" (??2@YAPEAX_K@Z) already defined in LIBCMTD.lib(new.obj) C:\Users\Xerxes\Documents\Visual Studio 2010\Projects\test1\test1\uafxcwd.lib(afxmem.obj)

問題在CRT和MFC library都有new delete等function, 需要先link MFC libray再link CRT

Solution:
Properties -> Linker --> Input --> Additional dependencies
加入;uafxcwd.lib;LIBCMTD.lib
順序不可以改變

使用CArray碰到error C2248: 'CObject::operator =' : cannot access private member declared in class 'CObject'

問題大概像是文章內所述,
照他的寫法也可以compile過,
不過看不太懂為什麼要這樣改?
