Question

Boost已安装并制作：brew install boost
向用户标题搜索路径添加标题路径/usr/local/Cellar/boost/1.53.0/include
将库路径/usr/local/Cellar/boost/1.53.0/lib添加到“库搜索路径”

的main.cpp

#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，会显示以下错误消息：

Undefined symbols for architecture x86_64:

有人对如何解决此问题有任何建议吗？

Answer 1

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。详情请阅读link

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

然后重建您的项目。如果仍然无法链接，请将change project的makefile编译器选项添加到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）。
