В приложении всего 3 библиотеки: SFML, TinyFD и OpenCV. Первые две работают превосходно, но вот OpenCV почему-то не хочет работать.
Библиотеку собирал из исходников, решил собрать с нуля когда по такой же причине падало моё предыдущее приложение.
Вот сама библиотека в проекте:
Далее её подключение в CMake:
cmake_minimum_required(VERSION 3.0)
project(ImagePixelizer VERSION 0.1)
set(CMAKE_CXX_STANDARD 20)
add_subdirectory(lib/tinyfd)
add_executable(ImagePixelizer src/main.cpp src/SelectFileDialog/FileDialog.cpp)
target_include_directories(ImagePixelizer PRIVATE
lib/SFML/include/
lib/OpenCV/include
lib/NFD/include
lib/wxWidgets/include
lib/tinyfd/include)
target_link_libraries(

И сама ошибка:

Чтобы получить эту ошибку, много сделать не пришлось:
#include <SFML/Graphics.hpp>
#include <opencv2/videoio.hpp>
#include "SelectFileDialog/FileDialog.hpp"
int main() {
sf::RenderWindow window(sf::VideoMode(800, 600), "Image Pixelizer");
cv::VideoCapture capture; // Использование API OpenCV
while (window.isOpen()) {
sf::Event event{};
while (window.pollEvent(event)) {
if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
window.display();
}
return 0;
}
Ошибка выбрасывается при любом использовании API OpenCV.
