Question

我编写了一个我在网上用opencv编写的简短示例程序时，过去几天一直在尝试解决我遇到的错误。应用程序的代码可以在下面找到，控制台命令和错误如下。任何和所有的帮助表示赞赏。

.cpp文件：

@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:hibernate.properties" })
public class RepositoryConfiguration {

@Autowired
private Environment environment;

@Bean(name="sessionFactory")
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setHibernateProperties(hibernateProperties());
    sessionFactory.setPackagesToScan(new String[] { "com.project" });
    return sessionFactory;
}

 @Bean
 public Properties hibernateProperties() {
 Properties properties = new Properties();
 properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
 properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
 properties.put("hibernate.hbm2ddl.auto", "update");// environment.getRequiredProperty("hibernate.hbm2ddl.auto")
 return properties;
 }

@Bean(name = "datasource")
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
    dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
    dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
    return dataSource;
}

 @Bean
 @Autowired
 @Qualifier(value = "sessionFactory")
 public HibernateTransactionManager transactionManager(SessionFactory s) {
 HibernateTransactionManager txManager = new HibernateTransactionManager();
 txManager.setSessionFactory(s);
 return txManager;
 }

控制台命令和错误：

#include <opencv2/highgui/highgui.hpp>
using namespace cv;

int main(){
    Mat img = imread("/home/pi/opencv/testPic.jpg",CV_LOAD_IMAGE_COLOR);
    imshow("opencvtest",img);
    waitKey(0);
    return 0;
}

您必须将您的二进制文件与OpenCV相关联...假设您正确安装了OpenCV，可以使用以下命令：

g++ -o cppTest cppTest.cpp -lopencv_core -lopencv_highgui -lopencv_imgproc

在Raspberry Pi上编译c ++ opencv应用程序时出错
