Ubuntu16.04编译rtl8811cu的网卡驱动，总是失败

[ChineseAStar]

设备：
新组了一台式机，买了个tplink的wdn5200h的无线网卡。
内核版本：
试了好几个内核版本：5.4、5.8、5.9、5.10。都是各自的最新版。
驱动代码：
试了几个

总共7千多行，就只放了开头和结尾。
问题：
对着方面不是很懂，试了2、3天没有头绪，有没有大佬给个答案。

gcc版本低了，不认识从5.4内核开始使用的 #define asm_inline asm __inline这种写法。
16.04我记得最初版是4.4内核，最终版是4.15内核，如果没有特别的需要，用旧版内核就可以编译了。
也可以升级gcc，或者自己把文件中的#define asm_inline asm __inline改成#define asm_inline asm凑合一下

谢谢，应该是这个原因。我换成ubuntu18.04版本编译就通过了，之前为了方便升级的内核版本呢太高了。
