我正在尝试安装 pcapsipdump，但是当我尝试制作时出现以下错误。安装了 libpcab 和 libpcap-devel，这是我通过“yum install libpcap libpcap-devel”完成的。我目前坚持如何进一步调试，所以我正在伸出援手。谢谢

[root@master-server pcapsipdump-code]# make
make-checks/libpcap.cpp: In function ‘int main()’:
make-checks/libpcap.cpp:2: error: ‘pcap_set_snaplen’ was not declared in this scope

g++ make-checks/libpcap.cpp -lpcap -o make-checks/libpcap

===
Required library not found: pcap
Please install it in your distribution-specific manner, e.g.:
yum install libpcap libpcap-devel
apt-get install tcpdump libpcap-dev
cd ~ports/net/libpcap && make install
===
make: *** [make-checks/libpcap] Error 1

yum install libpcap libpcap-devel 的输出

make debug 很长，但如果这有帮助，那么 end 在下面：

我有以下脚本，基本上我想要它做的是连接到各种服务器。查看有多少打开的文件，如果超过 50,000 则发送电子邮件。但是我需要检查的最后一台服务器超过 400,000。我的 OR 有问题，它不起作用。

如果我按原样运行这个当前脚本，即使没有达到任何限制，我也会收到警报电子邮件。请帮助我完成我的 OR 声明。

我在命令行中的输出显示：

Alert Server Issue 
AlertError S1:6326 S2:6355 S3:6242 S4:7171 S5:4694 S6:5284 S7:3973 S8:308432
