工程编入第三方的静态库出现错误的解决方法

在工程内编入第三方的功能,  包含.h和.lib就直接使用第三方提供的功能了. 这样肯定方便.

 

编译的时候通不过.

 

1.把编译不过的部分变成Dll的一部分, 主程序只调用Dll来引入第三方的功能. 如果有多个第三方的功能，分别封装Dll.

 

2.在Dll内调整Link设置, 知道编译通过为止. 主要是运行时库。

libcmt.lib(crt0init.obj) : error LNK2005: ___xc_z already defined in msvcrt.lib(cinitexe.obj)libcmt.lib(crt0init.obj) : error LNK2005: ___xc_a already defined in msvcrt.lib(cinitexe.obj)libcmt.lib(crt0init.obj) : error LNK2005: ___xi_z already defined in msvcrt.lib(cinitexe.obj)libcmt.lib(crt0init.obj) : error LNK2005: ___xi_a already defined in msvcrt.lib(cinitexe.obj)msvcrt.lib(MSVCRT.dll) : error LNK2005: _strncmp already defined in libcmt.lib(strncmp.obj)msvcrt.lib(MSVCRT.dll) : error LNK2005: _sprintf already defined in libcmt.lib(sprintf.obj)msvcrt.lib(MSVCRT.dll) : error LNK2005: _atoi already defined in libcmt.lib(atox.obj)msvcrt.lib(MSVCRT.dll) : error LNK2005: _strncpy already defined in libcmt.lib(strncpy.obj)

 

解决后的Link设置

 

 

通过后，编译有几个警告, 但是能用了.
