烦请告知操作系统和gcc的版本号

我有类似的报错 操作系统是Debian GNU/Linux 11 (bullseye) （在win10或win server2016下wmware起的虚拟机） gcc的版本是gcc version 10.2.1 20210110 (Debian 10.2.1-6) fdfs版本6.0.7 libfastcommon版本1.0.55 fastdfs-nginx-module版本1.22 nginx 1.15.1、1.18.0、1.21.5均是同样报错

make命令执行后输出：

感谢反馈，问题已修复，使用 master分支即可。 对于大于等于7.0的gcc，需要在CFLAGS中增加选项：-Wformat-truncation=0 -Wformat-overflow=0
