NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "pk_sc" for table "sc" ERROR: relation "pk_sc" already exists

这个NOTICE和ERROR是在使用PostgreSQL数据库时可能会出现的提示和错误信息，它们的含义如下：

NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "pk_sc" for table "sc"
这个提示表示在创建名为sc的表时，如果指定了主键，则会自动创建一个名为pk_sc的索引。这个索引是隐式创建的，意味着你不需要显式地创建它。

ERROR: relation "pk_sc" already exists
这个错误提示则是表示在执行创建索引的操作时，发现名为pk_sc的索引已经存在了。可能是由于之前执行了同样的创建操作，或者通过其他方式创建了同名的索引。需要检查一下是否已经存在同名的索引，如果确实是重复创建了，则可以直接删除之前创建的索引再重新创建即可。

根据您提供的信息，看起来您尝试使用SSH连接到主机lxslc702.ihep.ac.cn的端口22，但连接被远程服务器关闭了。关闭连接的原因可能有很多，例如网络问题、身份验证失败或服务器配置问题。要进一步诊断此问题，您可以尝试以下步骤：

1. 确保网络连接正常：检查您的网络连接是否正常，确保您可以访问远程服务器。

2. 检查身份验证凭证：确保您使用的身份验证凭证（例如用户名和密码、SSH密钥）是正确的，并且具有连接到远程服务器的权限。

3. 检查远程服务器配置：如果您有权限访问远程服务器的配置文件，请检查是否存在任何配置问题，例如防火墙设置、访问限制或SSH服务配置。

如果您仍然遇到问题，建议联系远程服务器的管理员或技术支持人员以获取更多帮助和支持。

这是一个编译错误，指出在文件 /data/ly/T113/i/program/8188/rtl8188eus-5.3.9/os_dep/linux/os_intfs.c 中的 rtw_os_ndev_register 函数中有一些问题。具体来说，该函数调用了一个未声明的函数 wiphy_net()，导致了编译错误。此外，该文件还有一个问题，即在 drv_types.h 文件中定义了一个宏 adapter_to_wiphy()，但在 os_intfs.c 文件中使用时，它引用了一个不存在的成员变量 adapter->wiphy。建议您检查这些问题并进行修复。
