I have following folder structure
-include->Header.h
->kernel.h
-kernel.cu
-Source.cpp
Now, Header.h here is public header and kernel.h is private. Source.cpp has a function which calls a function from kernel.cu and includes both the include files.
Source.cpp
#include "Header.h"
#include "kernel.h"
void getAverage(std::deque<cv::Mat> data, int numOfMats, cv::Mat& result)
{
computeAverage(data, numOfMats, result); //Umesh: here you should directly call renamed main function from kernel.cu
}
Header.h
#include <iostream>
#include <deque>
#include <opencv2/core/mat.hpp>
using namespace std;
void getAverage(std::deque<cv::Mat> data, int numOfMats, cv::Mat& result);
Now, the kernel.cu has the logic of computeAverage().
I wanted to create a library of this code, so I have written a CMake for this:
cmake_minimum_required (VERSION 3.9)
project(AverageLib LANGUAGES CXX CUDA)
find_package(CUDA 11.6 REQUIRED)
set(CMAKE_PREFIX_PATH "C:/OpenCV/opencv/build")
find_package(OpenCV REQUIRED COMPONENTS core imgproc highgui)
include_directories(${OpenCV_INCLUDE_DIRS})
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
add_library(AverageLib SHARED kernel.cu Source.cpp)
install(TARGETS AverageLib DESTINATION lib)
install(FILES include/Header.h include/kernel.h DESTINATION include)
After running the cmake it installs library in my C drive. But when I want to test it, I created a sample cpp file which calls getAverage() function and I linked the installed include folder and library, also linked the library in linker.
But it does not work, I get following error
Error LNK2019 unresolved external symbol "void __cdecl getAverage(class std::deque<class cv::Mat,class std::allocator<class cv::Mat> >,int,class cv::Mat &)"
I am not sure what wrong I am doing, can you please help?
Thank you in advance.
