将 Boost Regex 库与 GCC 5.2.0 链接时出现未定义的引用错误

undefined reference errors when linking the boost regex library with gcc 5.2.0

提问人：Emlyn Jose 提问时间：4/8/2016 最后编辑：einpoklumEmlyn Jose 更新时间：1/27/2017 访问量：802

问：

以下代码使用 GCC 4.9.2 成功编译，没有任何警告：

#include <memory>
#include <string>
#include <boost/regex.hpp>

int main()
{
boost::wregex wregex;
std::wstring text = L"foobar";
return boost::regex_match(text, wregex);
}

命令运行是：

g++ -I /opt/boost/x86_64/1.60.0/include -L /opt/boost/x86_64/1.60.0/lib test.cc  -lboost_regex

但在与 GCC 5.2.0 一起使用时显示以下错误：

您是否尝试过添加选项 -std=c++14（我在这里找到了它：solarianprogrammer.com/2016/03/06/... )

是的，我检查了这个页面。但这没有用。谢谢！

好的，您的 boost 版本 （1.60） ABI 是否与 gcc 5.2.0 兼容，或者您是否必须安装新的 boost 版本？

对不起，我不熟悉 ABI。我应该如何检查我的 boost 版本是否与 gcc 5.2.0 兼容？

我阅读了这个 ABI 并通过添加如下宏来构建 boost 1.60.0： ./bootstrap.sh ./bjam -j4 define=_GLIBCXX_USE_CXX11_ABI=0 stage 但即便如此，也没有变化。这是正确的做法吗？顺便说一句，我通过运行g++手动尝试了这个，如下所示，它没有失败： g++ -I /opt/boost/x86_64/1.60.0/include -L /opt/boost/x86_64/1.60.0/lib test.cc -D_GLIBCXX_USE_CXX11_ABI=0 -lboost_regex在构建提升时要进行任何其他更改？

答： 暂无答案

上一个：boost 文件系统 （1.63） 在对 QNX 进行交叉编译后失败并出现未定义的引用错误
