问题1：编译报错“snmp.c:21:11: fatal error: net-snmp/net-snmp-config.h: No such file or directory”

编译参数

./configure -prefix=/usr/local/zabbix -sysconfdir=/etc/zabbix/ -enable-server -enable-agent -with-net-snmp=/usr/local/snmp/bin/net-snmp-config -with-libcurl -with-mysql=/usr/local/mysql/bin/mysql_config -with-libxml2

编译错误信息

snmp.c:21:11: fatal error: net-snmp/net-snmp-config.h: No such file or directory
 # include <net-snmp/net-snmp-config.h>
           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

解决方法
安装SNMP开发包

CentOS/RHEL/Rocky
yum install -y net-snmp-devel
或者dnf install -y net-snmp-devel

Debian/Ubuntu
apt install -y libsnmp-dev

问题2：MySQL8.0升级8.4后启动Zabbix Server报错

错误信息

zabbix_server[5843]: /usr/local/zabbix/sbin/zabbix_server: error while loading shared libraries: libmysqlclient.so.21: cannot open shared object file: No such file or directory

解决方法
重新编译安装Zabbix，指定MySQL链接库，编译参数如下

MYSQL_CONFIG=/usr/local/mysql/bin/mysql_config
MYSQL_LFLAGS=$($MYSQL_CONFIG --libs | tr ' ' '\n' | grep '^-L' | sort -u | tr '\n' ' ')
MYSQL_RPATH=$($MYSQL_CONFIG --libs | tr ' ' '\n' | grep '^-L' | sort -u | sed 's|^-L|-Wl,-rpath,|' | tr '\n' ' ')

./configure -prefix=/usr/local/zabbix -sysconfdir=/etc/zabbix/ -enable-server -enable-agent -with-net-snmp=/usr/local/snmp/bin/net-snmp-config -with-libcurl --with-mysql="$MYSQL_CONFIG" LDFLAGS="$MYSQL_LFLAGS $MYSQL_RPATH" -with-libxml2

问题3：编译报错“cannot find pkg-config package for libpcre2”

configure: error: cannot find pkg-config package for libpcre2

解决方法
安装PCRE2正则库的开发包
Debian/Ubuntu
apt install libpcre2-dev

CentOS/RHEL/Rocky
yum install pcre2-devel
