System information (version)
  • OpenCV => 4.3.0
  • Operating System / Platform => Windows 64 Bit
  • Compiler => Visual Studio 2017
Detailed description

I would like to debug into OpenCV's C++ source code, to see function / algorithm implementation details. Say, I'm interested in how cv::imread( ) implemtented, by using the prebuilt OpenCV Windows package, it just complains "can't find loadsave.cpp". Thus I turn to built OpenCV from source with VS2017.

After building & installation of my customized version, I write a simple code as executable target, aims to providing break point entry, for further debugging into OpenCV source. However, when running, it complains "zlib1.dll" can't find (release mode), "zlibd1.dll" can't find (debug mode). Wired. Note that I've prepend "/path/to/installed/opencv/vc15/x64/bin" and re-opened Visual Studio.

Steps to reproduce
  1. Git clone OpenCV4.3's source code
cd d:/work/
git clone https://github.com/opencv/opencv
cd opencv
git checkout -b 4.3.0 4.3.0
  1. Compile OpenCV with:
@echo off

set BUILD_DIR=vs2017-x64
::set OpenBLAS_HOME=D:/lib/openblas/0.2.14-Win64-int64


if not exist %BUILD_DIR% md %BUILD_DIR%

cd %BUILD_DIR%

cmake -G "Visual Studio 15 2017 Win64" ^

  1. Write a simple CMake driven C++ project.

project(ocv_demo)
find_package(OpenCV REQUIRED)
add_executable(run src/main.cpp)
target_link_libraries(run ${OpenCV_LIBS})

#include <opencv2/opencv.hpp>
int main() {
    cv::Mat im = cv::Mat::ones(100, 100, CV_64FC3);
    im = im * 0.73 * 255;
    cv::imwrite("res-cpp.bmp", im);
    return 0;
}

generate Visual Studio solution by:

cmake ../.. -G "Visual Studio 15 2017 Win64" -DOpenCV_DIR="D:/work/opencv-4.3.0/build/vs2017-x64/install"
  1. Run the new generated visual studio's run target.

Just run it, and will get message like "can't find zlib1.dll" (I'm not English language version of VS2017 thus it maybe not exactly what it says).

  1. What's your PATH?
C:\Users\zz>echo %PATH%

Note

I know there's a workaround

find the missing dll which is complained by VS2017, put it into installation's bin directory.

However, I don't feel it convenient and some other people will also meet that problem, thus I put the issue here.
