这个错误是由于缺少 OpenSSL 库或版本不支持导致的。解决方法如下:
1. 确保 OpenSSL 库已经安装。在 Linux 上,您可以使用包管理器安装 OpenSSL 库,例如 apt-get、yum 等。在 Windows 上,您可以从 OpenSSL 官网下载适合您的版本并安装。
2. 如果您已经安装了 OpenSSL 库,但是仍然遇到此错误,请确保您使用的是支持的版本。MySQL 可以使用 OpenSSL 1.0.x 或 1.1.x 版本。检查您的 OpenSSL 版本并确保它与 MySQL 兼容。
3. 如果您使用的是自定义 OpenSSL 安装路径,请在 WITH_SSL 选项中指定路径,例如:-DWITH_SSL=/path/to/openssl。
4. 如果您在构建 MySQL 时使用了系统 OpenSSL 库,并且仍然遇到此错误,请确保您的系统 OpenSSL 库版本与 MySQL 兼容。您可以尝试使用自定义 OpenSSL 安装路径或升级您的系统 OpenSSL 库。
如果您仍然无法解决此问题,请提供更多上下文信息,例如您正在尝试构建什么,使用的操作系统和 CMake 版本等。

Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
It seems like you are encountering an error related to the configuration of your Spring Boot application during testing. The error message suggests that you need to use either `@ContextConfiguration` or `@SpringBootTest(classes=...)` in your test class.
To fix this issue, you can do one of the following:
1. Use `@ContextConfiguration` annotation: Add the `@ContextConfiguration` annotation to your test class and specify the configuration classes or XML files that should be used for the test. For example:
```java
@RunWith(SpringRunner.class)
@ContextConfiguration(classes = YourApplicationConfig.class)
public class YourTestClass {
// ...
}
```
2. Use `@SpringBootTest` annotation: Add the `@SpringBootTest` annotation to your test class and specify the main configuration class of your Spring Boot application using the `classes` parameter. For example:
```java
@RunWith(SpringRunner.class)
@SpringBootTest(classes = YourApplication.class)
public class YourTestClass {
// ...
}
```
Make sure to replace `YourApplicationConfig` and `YourApplication` with the appropriate classes from your project.
These annotations help Spring Boot to load the necessary configurations for your tests.
Could not find a file system implementation for scheme 'hdfs'. The scheme is not directly supported by Flink and no Hadoop file system to support this scheme could be loaded
This error message indicates that Flink is unable to find a file system implementation for the 'hdfs' scheme. Flink does not natively support Hadoop Distributed File System (HDFS), so you need to configure it to work with HDFS.
To resolve this issue, you can follow these steps:
1. Make sure you have the Hadoop libraries installed on your Flink cluster.
2. Update the Flink configuration file (`flink-conf.yaml`) and add the following properties:
```
fs.hdfs.hadoopconf: /path/to/hadoop/conf
fs.hdfs.hadoop.user: hdfs
```
Replace `/path/to/hadoop/conf` with the actual path to your Hadoop configuration directory.
Replace `hdfs` with the Hadoop user you want to use (e.g., `hadoop`).
3. Restart your Flink cluster for the changes to take effect.
By configuring Flink with the appropriate Hadoop libraries and settings, it should be able to load the Hadoop file system implementation for the 'hdfs' scheme and work with HDFS.
