OSX Caffe編譯失敗，出現預期的表達式錯誤

Question

我一直在嘗試在運行OSX 10.13.6的mac上安裝Caffe

我遵循了幾個指南，包括caffe網站上的安裝指南。 我已經刪除了所有內容並重新啟動了幾次。 無論怎樣，我都會遇到同樣的問題。 當我去編譯所有我得到的東西

Scanning dependencies of target caffeproto [ 1%] Building CXX object src/caffe/CMakeFiles/caffeproto.dir/__/__/include/caffe/proto/caffe.pb.cc.o In file included from /Users/Name/Documents/Programming/PythonEnv/caffe/build/include/caffe/proto/caffe.pb.cc:4: In file included from /Users/Name/Documents/Programming/PythonEnv/caffe/build/include/caffe/proto/caffe.pb.h:9: /usr/local/include/google/protobuf/stubs/common.h:209:17: error: expected expression OnShutdownRun([](const void* p) { delete static_cast<const T*>(p); }, p); ^ In file included from /Users/Name/Documents/Programming/PythonEnv/caffe/build/include/caffe/proto/caffe.pb.cc:4: In file included from /Users/Name/Documents/Programming/PythonEnv/caffe/build/include/caffe/proto/caffe.pb.h:25: In file included from /usr/local/include/google/protobuf/generated_message_table_driven.h:34: In file included from /usr/local/include/google/protobuf/map.h:49: In file included from /usr/local/include/google/protobuf/map_type_handler.h:35: In file included from /usr/local/include/google/protobuf/wire_format_lite_inl.h:43: /usr/local/include/google/protobuf/message_lite.h:117:3: error: unknown type name 'constexpr' constexpr const T& get() const { return reinterpret_cast<const T&>(union_); }

我也嘗試過使用CMake並遇到同樣的問題。 我不知道從哪里開始。 我對構建流程並不是非常了解，所以我很抱歉，如果這是模糊的，並樂意提供其他任何可能有助於解決此問題的信息。

謝謝！

Answer 1

如果使用make編譯，請按如下方式更改Makefile ：

- CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS)

+ CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11

Answer 2

這與此處報告的問題相同： https ： //trac.macports.org/ticket/57093#comment：1

編譯器需要使用C ++ 11。 嘗試在CMakeLists.txt進行此更改：

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()

Answer 3

您只需要用protobuf v3.5.1替換最新版本的protobuf。

wget https://github.com/protocolbuffers/protobuf/archive/v3.5.1.zip

您需要下載到源代碼，並自行編譯。
