libstdc++: DSO missing from command line
提问by wolx
I am having trouble implementing a gtkmm application's makefile. I have implemented a simple solution, however, I am getting the following error:

I met the same issue when built openCV libraries
我在构建 openCV 库时遇到了同样的问题
$ gcc DisplayImage.cpp `pkg-config opencv --libs --cflags` -o DisplayImage
/usr/bin/ld: /tmp/ccbyJ7Ms.o: undefined reference to symbol '_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEED1Ev@@GLIBCXX_3.4.21'
//usr/lib/i386-linux-gnu/libstdc++.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

[解决]
For gcctry adding -lstdc++to your command.
对于gcc，尝试添加-lstdc++到您的命令中。
$ gcc DisplayImage.cpp `pkg-config opencv --libs --cflags` -o DisplayImage -lstdc++
For g++it will link libstdc.so.6++automatically
对于g++，它将自动链接libstdc.so.6++
$ g++ DisplayImage.cpp `pkg-config opencv --libs --cflags` -o DisplayImage

I had same problem it was solved by addiing -lstdc++ in command line.
我有同样的问题，它是通过在命令行中添加 -lstdc++ 来解决的。

I had a similar problem when compiling zeromq (zmq) into my project. Adding -lstdc++to the link line in my makefile solved the problem.
我在将 zeromq (zmq) 编译到我的项目中时遇到了类似的问题。将-lstdc++添加到我的 makefile 中的链接行解决了这个问题。
