使用 python 编译 caffe 的问题，未定义对"std：：__cxx11：：..."的引用。

Question

我曾经在Ubuntu 14.04上使用WITH_PYTHON_LAYER:=1编译成功caffe。然后我切换到Ubuntu 16.04，使用相同的设置但不同的内置软件，例如16.04的g++ 5.4而不是14.04的g++ 4.8，我无法用python编译caffe。你能就这个问题给我一些建议吗?下面是我得到的错误信息

Answer 1

按照cmake的官方安装说明解决了这个问题。

解决方法:
1. 在您的CAFFE/目录中运行make clean
2. compile_caffe_with_cmake.
