Hi Guys,
wondering if someone can help me out a bit, i have a ubuntu 9.04 server installation and its a VERY minimal install of ubuntu. i have installed nagios and sendmail got it all working great so far, how ever i seem to have run into a problem and cannot find a way to fix it.
i want to monitor Mysql db’s on some of my windows hosts but when i checked /usr/local/nagios/libexec/ the check_MYSQL plugin is missing. i followed the ubuntu quickstart guide in the Nagios documentation and as a result i installed the plugins and compiled them but it seems to be missing the mysql one.
here is an output from the manual compile of the check_Mysql plugin
root@ubuntu:~/downloads/nagios-plugins-1.4.11/plugins# make check_mysql
if gcc -DLOCALEDIR=\"/usr/local/nagios/share/locale\" -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../lib -I../gl -I../intl -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

i cannot work out what is wrong, do i need to have anything installed before hand in order to get it working? because as i say this linux install is very minimal, i am still getting my head around linux so would be really greatful if you could give nice clear replies to save confusing me 
thanks
Kris
EDIT
needed to install the mysql libs to get this working and just re-run the make commands to install the plugins, all sorted and working
