  1. Boost 由以下人员安装和制作：brew install boost
  2. 将标题路径添加/usr/local/Cellar/boost/1.53.0/include到用户标题搜索路径
  3. 将库路径添加/usr/local/Cellar/boost/1.53.0/lib到库搜索路径

主文件

#include <fstream>
#include <sstream>
#include <string>
#include "test.cpp"

void test(){
    Test instance(true, 'm', 50, 17.89, "fuzhijie");
    stringstream binary_sstream; 
    boost::archive::binary_oarchive binary_oa(binary_sstream);
    binary_oa << instance;
}

int main(int argc, const char * argv[])
{
    test();
    return 0;
}

当我按 CTRL+b 时，显示以下错误消息：

Undefined symbols for architecture x86_64:

有人对如何解决这个问题有任何建议吗？

原因可能是你有编译器 gcc5 或 gcc6。并且您的代码在您的 boost 库中使用了不同的编译标志。详细请阅读此链接

如果您可以重新编译您使用的所有不兼容的库，请使用编译器选项

-D_GLIBCXX_USE_CXX11_ABI=1

然后重建你的项目。如果仍然无法链接，请将更改项目的 makefile 编译器选项添加为 0。

-D_GLIBCXX_USE_CXX11_ABI=0

======更新=======

真正的解决方案应该是为 gcc6 或 gcc5 安装新的 boost 库 (v1.62)。
