Question

我最近一直试图移植C ++应用程序。我相信我拥有它所有的依赖关系等等所有这些都可以编译。但是，当它链接它时，我得到了许多奇怪的未定义的引用错误。

/usr/local/lib/libglibmm-2.4.so.7.0: undefined reference to `std::basic_istream<char, std::char_traits<char> >::seekg(long, std::_Ios_Seekdir)'
/usr/local/lib/libglibmm-2.4.so.7.0: undefined reference to `std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >::_S_empty_rep_storage'
/usr/local/lib/libxml++-2.6.so.0.1: undefined reference to `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_S_empty_rep_storage'
/usr/local/lib/libxml++-2.6.so.0.1: undefined reference to `std::__default_alloc_template<true, 0>::deallocate(void*, unsigned long)'

什么会导致这种错误？链接错误是什么意思？我无法理解gcc给出的复杂模板错误消息..

完整的链接命令：

此外，我没有得到任何关于丢失文件的链接错误，只是关于奇怪的字符串和文件流丢失的东西

Answer 1

使用g ++链接C ++应用程序，将C ++标准库添加到链接阶段。

奇怪的问题移植应用程序。标准库中未定义的引用错误
