python - 使用 python 编译 caffe 的问题，对 `std::__cxx11::....' 的 undefined reference

Question

我曾经在 Ubuntu 14.04 上使用 WITH_PYTHON_LAYER:=1 成功编译了 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。你能给我一些关于这个问题的建议吗？以下是我得到的部分错误信息

Answer 1

按照 cmake 的官方安装说明解决了这个问题。

解决步骤:
1. 在您的 CAFFE/目录中运行 make clean
2. 后续说明compile_caffe_with_cmake .
