关于这样的错误 libcpmtd.lib(string.obj) : error LNK2005: "public: void __thiscall

VC2008下 在一个动态库工程中, 改成了编程静态库, 成功编译, 但使用静态库的工程编译时就出现下面一堆连接错误.

 

经过查找 解决方法如下:

说是因为 Project->C/C++->Code Generation->Runtime Library 这个选项，LIB和主程序（EXE）里选择的不一致引起的。后来改成一样就好了。

 

把exe工程 改为/MTD(因为Lib工程是选择/MTD的) 编译还是错误

于是 把EXE工程和Lib工程都选择为/MDD 成功编译
