我一直在尝试在运行OSX 10.13.6的Mac上安装Caffe
我遵循了一些指南，包括caffe网站上的安装指南。我已经擦除了所有内容并重新启动了几次。无论如何，我都会遇到同样的问题。当我去编译所有东西时，我会得到这个

我也尝试过使用CMake并遇到相同的问题。我不确定从这里去哪里。对于构建过程，我的知识并不十分了解，因此，我对此是否含糊表示歉意，并很乐意提供其他任何可能有助于解决此问题的信息。
谢谢！

如果使用make进行编译，请按以下方式更改Makefile：
- CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS)
+ CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11

这是与此处报告的问题相同的问题：https://trac.macports.org/ticket/57093#comment:1
编译器需要使用C ++ 11。尝试在CMakeLists.txt中进行此更改：
if(UNIX OR APPLE)
- set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall")
+ set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall -std=c++11")
endif()

您只需要用protobuf v3.5.1替换protobuf的最新版本即可。
wget https://github.com/protocolbuffers/protobuf/archive/v3.5.1.zip
您需要下载源代码，然后自己进行编译。
