Building Caffe cpp_classification пример во внешнем контексте

Question

Я уже настроил и создал Caffe с нуля в режимах CPU_ONLY и GPU_ONLY (с соответствующими образцами и инструментами); и довольно удовлетворены результатами из коробки.

Однако я начинаю свой собственный проект, полученный из примера cpp_classification, и испытывает трудности с его созданием независимо от общей системы сборки Caffe. Таким образом, я вернулся к примеру cpp_classification и работал над созданием этого как автономного (просто для того, чтобы я ничего не оставлял) и сталкивался с подобными ошибками.

Я разделяю содержимое вывода ошибок сборки и CMakeLists.txt с вами в надежде, что кто-то, кто успешно поднял пример cpp_classification, может предоставить руководство.

я сузил Моделировочные ошибки я получаю к следующему:

Моих соответствующему CMakeList.txt выглядит следующим образом:

cmake_minimum_required(VERSION 3.6) 
project(cpp_classification) 
list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake") 

set(CAFFE_HOME ~/caffe/distribute) 

find_package(OpenCV REQUIRED) 
find_package(Caffe REQUIRED) 
find_package(GTest REQUIRED) 
find_package(glog REQUIRED) 
find_package(Boost REQUIRED COMPONENTS system) 
find_package(Protobuf REQUIRED) 

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11") 

set(SOURCE_FILES classification.cpp) 

include_directories(${CAFFE_HOME}/include ${Boost_INCLUDE_DIRS}) 
link_directories(${CAFFE_HOME}/lib ${Boost_LIBRARY_DIRS}) 

add_executable(cpp_classification 
     ${SOURCE_FILES} 
     ${GLOG_INCLUDE_DIR} 
     ${Caffe_INCLUDE_DIR} 
     ${Protobuf_INCLUDE_DIR}) 

TARGET_LINK_LIBRARIES(cpp_classification 
     ${OpenCV_LIBS} 
     ${Boost_LIBRARIES} 
     ${GLOG_LIBRARY}

     ${Protobuf_LIBRARY}) 

Answer 1

попробовать с

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_GLIBCXX_USE_CXX11_ABI=0")

Он сообщает gcc использовать старый ABI для <string>.
