我正在尝试在 catkin 环境中编译具有 openMP 支持的 OpenNN。我已经编译它但没有成功意识到我的代码是在单个线程中执行的。

我的 CMakeLists.txt 是：

cmake_minimum_required(VERSION 2.8.3)
project(opennn)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package(catkin REQUIRED
)

## System dependencies are found with CMake's conventions
# find_package(Boost REQUIRED COMPONENTS system)
find_package(Eigen3 REQUIRED)

find_package(OpenMP)
if(OPENMP_FOUND)
message (STATUS “OpenMP found ${OpenMP_INCLUDE_DIRS}”) 
set(CMAKE_CXX_FLAGS “${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}”)
set(CMAKE_C_FLAGS “${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}” )
else(OPENMP_FOUND)
message (STATUS “OpenMP not found”)
endif()

target_link_libraries(opennn ${Eigen_LIBRARIES})

这会在编译时引发以下错误：
