本文解决了一个在Visual C++ 2008环境中从动态库转换为静态库后出现的链接错误问题。主要原因是项目设置中运行时库选项不一致导致重复定义错误。

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
