First of all I cant use --with-nagios-user=nagios, it says the command is depricated. Deleted it and is hoping it uses both nagios as user and group as default. Main problem is that I get errors when compiling plugins for mysql. Compile seems fine until I get this error: Making all in plugins make[2]: Entering directory `/usr/local/nagios/libexec/nagios-plugins-1.4.6/plugins' if gcc -DLOCALEDIR=\"/usr/local/nagios/share/locale\" -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../lib -I../gl -I../intl -I/usr/include/ldap -I/usr/include -I/usr/kerberos/include -I'/usr/include' -g -O2 -MT check_mysql-check_mysql.o -MD -MP -MF ".deps/check_mysql-check_mysql.Tpo" -c -o check_mysql-check_mysql.o `test -f 'check_mysql.c' || echo './'`check_mysql.c; \ then mv -f ".deps/check_mysql-check_mysql.Tpo" ".deps/check_mysql-check_mysql.Po"; else rm -f ".deps/check_mysql-check_mysql.Tpo"; exit 1; fi check_mysql.c:51:19: mysql.h: No such file or directory check_mysql.c:52:20: errmsg.h: No such file or directory check_mysql.c:58: `MYSQL_PORT' undeclared here (not in a function) check_mysql.c: In function `main': check_mysql.c:73: `MYSQL' undeclared (first use in this function) check_mysql.c:73: (Each undeclared identifier is reported only once check_mysql.c:73: for each function it appears in.) check_mysql.c:73: parse error before "mysql" check_mysql.c:74: `MYSQL_RES' undeclared (first use in this function) check_mysql.c:74: `res' undeclared (first use in this function) check_mysql.c:75: `MYSQL_ROW' undeclared (first use in this function) check_mysql.c:75: parse error before "row" check_mysql.c:91: `mysql' undeclared (first use in this function) check_mysql.c:93: `MYSQL_READ_DEFAULT_GROUP' undeclared (first use in this function) check_mysql.c:97: `CR_UNKNOWN_HOST' undeclared (first use in this function) check_mysql.c:99: `CR_VERSION_ERROR' undeclared (first use in this function) check_mysql.c:101: `CR_OUT_OF_MEMORY' undeclared (first use in this function) check_mysql.c:103: `CR_IPSOCK_ERROR' undeclared (first use in this function) check_mysql.c:105: `CR_SOCKET_CREATE_ERROR' undeclared (first use in this function) check_mysql.c:112: warning: passing arg 1 of `strlen' makes pointer from integer without a cast check_mysql.c:112: warning: passing arg 2 of `memcpy' makes pointer from integer without a cast check_mysql.c:112: warning: passing arg 1 of `__strdup' makes pointer from integer without a cast check_mysql.c:116: `CR_SERVER_GONE_ERROR' undeclared (first use in this function) check_mysql.c:118: `CR_SERVER_LOST' undeclared (first use in this function) check_mysql.c:120: `CR_UNKNOWN_ERROR' undeclared (first use in this function) check_mysql.c:127: warning: passing arg 1 of `strlen' makes pointer from integer without a cast check_mysql.c:127: warning: passing arg 2 of `memcpy' makes pointer from integer without a cast check_mysql.c:127: warning: passing arg 1 of `__strdup' makes pointer from integer without a cast check_mysql.c:134: warning: passing arg 1 of `strlen' makes pointer from integer without a cast check_mysql.c:134: warning: passing arg 2 of `memcpy' makes pointer from integer without a cast check_mysql.c:134: warning: passing arg 1 of `__strdup' makes pointer from integer without a cast check_mysql.c:146: `row' undeclared (first use in this function) check_mysql.c:147: warning: passing arg 1 of `strlen' makes pointer from integer without a cast check_mysql.c:147: warning: passing arg 2 of `memcpy' makes pointer from integer without a cast check_mysql.c:147: warning: passing arg 1 of `__strdup' makes pointer from integer without a cast check_mysql.c:165: `MYSQL_FIELD' undeclared (first use in this function) check_mysql.c:165: `fields' undeclared (first use in this function) check_mysql.c: In function `print_help': check_mysql.c:367: `MYSQL_PORT' undeclared (first use in this function) make[2]: *** [check_mysql-check_mysql.o] Error 1 make[2]: Leaving directory `/usr/local/nagios/libexec/nagios- plugins-1.4.6/plugins' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/nagios/libexec/nagios-plugins-1.4.6' make: *** [all] Error 2 Anyone have any ideas how to get this working?
