Hi,
I have installed ndoutils in a 64-bit centOS-5.2 box. I just followed the steps which i used to follow while installing in 32-bit. In 32-bit box all worked fine.
But now, when I start the service ndoutils, The output is

[HTML]Starting ndo2db:Support for the specified database server is either not yet supported, or was not found on your system.
[/HTML]


What's wrong in that. The service ndoutils is not starting

I have given the command

./installdb -u nagios -p nagios -h localhost -d nagios

Then, the output is
Database installed successfully.

Please try to resolve this error.

Thanks,
Prakash.

Finally the problem is resolved. While working on a 64 bit OS, we should compile ndoutils as follows.

./configure --prefix=/monitoring/nagios/ --enable-mysql --with-mysql-lib=/usr/lib64/mysql

make

This solved my problem

Regards,
Prakash.

The error is because NDOUtils was not getting the required MYSQL libraries.

This is how I solved it in a 64 Bit Ubuntu 12 system.

The requisite MySQL client libraries can be installed by running:

apt-get install libmysqlclient15-dev
--> This installs the required 64bit MySQL libraries for client.

Then rerun the configuration file for building NDOUtils

In 64-Bit Ubuntu Linux System run it as:
./configure --prefix=$NAGIOS_HOME --enable-mysql --with-mysql-lib=/lib/x86_64-linux-gnu/

--> If nagios home directory is /usr/local/nagios, then set NAGIOS_HOME to it, or set it as per your environment.
--> In Ubuntu linux MySQL version 5.5.24, has the requisite libraries located at /lib/x86_64-linux-gnu
or else find out where it is in your system by running :
ldconfig -v | grep mysql

Then rebuild NDOUtils my rerunning make

Can I just point out that the thread is from 2008(!).
The current answer may be correct, but possibly not for the time it was asked ...
