AFL QEMU模式安装报错（afl-2.52b & qemu-2.10.0）[已解决]

搭建afl-qemu模块的时候，碰到了如下2个报错：

xxxxxxxx/qemu/linux-user/syscall.c:253:16: error: static declaration of ‘gettid’ follows non-static declaration
253 | _syscall0(int, gettid)

make: *** [Makefile:326: subdir-x86_64-linux-user] Error 2

根据错误提示可知，问题出在syscall.c这个c程序文件里，具体涉及到的位置应该就是‘gettid’和‘SIOCGSTAMPNS’这2块内容。
在网上找呀找呀找&#x
