c++ - File.cpp.o: OpenPose flags的多重定义 CMakeFiles/.../main.cpp.o: 首先定义在这里
问题描述
我已经多次发现这个问题,并且在这里(在 stackoverflow 上)和其他地方(谷歌搜索)找到了几十个答案,但没有任何效果。起初,我将所有代码都放在一个文件中,并且一切正常。但是现在,我需要将代码拆分为多个文件,创建一些类等等,所以我创建了以下文件:
标准数据文件
#pragma once
#include <iostream>
#include <fstream>
#include <iomanip>
#include <ctime>
// opencv
#include <opencv2/opencv.hpp>
// openpose
#include <openpose/flags.hpp>
#include <openpose/headers.hpp>
#include "driver-keypoints.h"
驱动程序关键点.h
#pragma once
class DriverKeypoints
{
public:
DriverKeypoints();
static const int NOSE = 0;
static const int NECK = 1;
static const int R_SHOULDER = 2;
static const int R_ELBOW = 3;
static const int R_WRIST = 4;
static const int L_SHOULDER = 5;
static const int L_ELBOW = 6;
static const int L_WRIST = 7;
static const int MID_HIP = 8;
static const int R_HIP = 9;
static const int L_HIP = 12;
int get_video_keypoints();
protected:
void save_keypoints(const std::shared_ptr<std::vector<std::shared_ptr<op::Datum>>>& datums_ptr,
std::string out_file, bool is_first);
void configure_wrapper(op::Wrapper& op_wrapper);
};
驱动程序关键点.cpp
#include "stdafx.h"
// Custom OpenPose flags
// TODO: here should not have been an absolute path
DEFINE_string(output_path, "/path/to/output/openpose/", "Path to save required keypoints.");
DEFINE_bool(no_display, false, "Enable to disable the visual display.");
void DriverKeypoints::save_keypoints(const std::shared_ptr<std::vector<std::shared_ptr<op::Datum>>> &datums_ptr,
std::string out_file, bool is_first) {
}
void DriverKeypoints::configure_wrapper(op::Wrapper &op_wrapper) {
}
int DriverKeypoints::get_video_keypoints() {
}
主文件
#include "stdafx.h"
int main(int argc, char** argv) {
FLAGS_disable_multi_thread = true;
FLAGS_net_resolution = "-1x192";
FLAGS_number_people_max = 0;
// Parsing command line flags
gflags::ParseCommandLineFlags(&argc, &argv, true);
// run parse keypoints from video
DriverKeypoints driver_keypoints;
return driver_keypoints.get_video_keypoints();
}
CMakeLists.txt
cmake_minimum_required(VERSION 3.14)
project(my_project)
set(CMAKE_CXX_STANDARD 14)

find_package(Caffe REQUIRED)

# TODO: here should not have been an absolute path
include(/home/path_to_openpose/openpose/cmake/Utils.cmake)
set(SOURCE_FILES main.cpp driver-keypoints.cpp)
add_executable(anomalies_analysis ${SOURCE_FILES})
target_link_libraries(
anomalies_analysis
${OpenCV_LIBS}
${CUDA_LIBRARIES}
openpose
gflags
)
我收到以下错误:
CMakeFiles/anomalies_analysis.dir/driver-keypoints.cpp.o:(.data+0x0): multiple definition of `fLI::FLAGS_logging_level'
CMakeFiles/anomalies_analysis.dir/main.cpp.o:(.data+0x0): first defined here

CMakeFiles/anomalies_analysis.dir/main.cpp.o:(.bss+0x1): first defined here
...
有很多类型的答案:
- 您应该将某些内容声明为内联(但这是不可能的)
- 你应该只定义一次(但我认为我正在这样做,看起来问题出在 include 中
openpose/flags.hpp
,但我有#pragma once
instdafx.h
,那么问题出在哪里?)
请你帮助我好吗?我在 C/C++ 编程方面经验不足。非常感谢。
解决方案
我知道这已经很晚了,但是我遇到了类似的问题,并且弹出了此线程。
我的代码在一个文件中运行良好,然后当我创建一个头文件并在多个位置#included 时给了我类似的错误。就我而言,我的头文件中有 DEFINE_type() 而不是 DECLARE_type(),这会导致问题,因为变量被定义了不止一次。我会仔细检查您在头文件中使用的是 DECLARE_ 方法而不是 DEFINE_ 方法。
