static-reloc.c:(.text+0x34): undefined reference to `main' collect2.exe: error: ld returned 1 exit status

This error message indicates that the linker was unable to find a definition for the main function in your program. This can occur if you have not provided a main function, or if there is a problem with the compilation or linking process.

To fix the issue, make sure that you have defined a main function in your program and that it is properly declared and defined. Also, check that all necessary header files are included and that any external libraries are properly linked.

这个错误是因为链接器找不到名为“main”的函数。这通常是因为缺少主函数而导致的。请检查您的代码，确保其中有一个名为“main”的函数，它是程序的入口点。如果您的代码中确实有一个名为“main”的函数，则可能是编译器或编译选项的问题。您可以尝试检查编译器选项，确保它们正确设置，以便正确地生成可执行文件。

import com.google.firebase.crashlytics.buildtools.reloc.org.apache.http.client.methods.HttpPost;失败

这是因为 `org.apache.http.client.methods.HttpPost` 类已经被弃用了，不再建议使用。相反，您应该使用 `java.net.http.HttpClient` 和 `java.net.http.HttpRequest` 来发送 HTTP 请求。您可以尝试将以下代码添加到您的项目中，以使用新的 HTTP 客户端发送 POST 请求：

import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.net.http.HttpResponse.BodyHandlers;

public class Example {
    public static void main(String[] args) throws Exception {
        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
                .uri(URI.create("https://example.com/api"))
                .header("Content-Type", "application/json")
                .POST(HttpRequest.BodyPublishers.ofString("Your JSON payload here"))
                .build();

        HttpResponse<String> response = client.send(request, BodyHandlers.ofString());
        System.out.println(response.statusCode());
        System.out.println(response.body());
    }
}

请注意，此代码需要 Java 11 或更高版本才能运行。如果您使用的是旧版本的 Java，请尝试使用其他 HTTP 客户端库，例如 Apache HttpClient。
