Fix Errors During Installing MySQL Include Files On Unix Ubuntu!

Amazon This happened while I was installing Sphinx search engine. I got an error saying I have to install MySQL include files. How do I do it?

My Unix version is Ubuntu 9.10. Here's what happens. When I run ./configure tool to install Sphinx I got the following error:

configure: error: invalid MySQL root directory '/var/lib/mysql'; neither bin/mysql_config, nor include/ and lib/ were found there
To give you some context into why this is needed, if you install any application that needs to communicate with your MySQL server you'll have to let that application know the MySQL protocol via MySQL libraries in the form of MySQL include files. Note this problem is NOT limited to Sphinx search engine only; whatever Unix application software that needs to talk to MySQL server also applies!

To solve this error I needed to run the following command:

sudo apt-get install libmysql++-dev
However it says it cannot find the library and asks me to run 'apt-get update', but when I do that I get a bunch of 404 errors like the following.

This happens because my repositories are out of date. So I updated my sources.list (Where is sources.list? It is usually located at /etc/apt/sources.list) to (after backing it up of course) to the default of Ubuntu 9.10 which is the following:

# deb cdrom:[Ubuntu-Server 9.10 _Karmic Koala_ - Release i386 (20091027.2)]/ karmic main restricted

#deb cdrom:[Ubuntu-Server 9.10 _Karmic Koala_ - Release i386 (20091027.2)]/ karmic main restricted
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to

Now I run 'apt-get update' and 'apt-get install libmysql++-dev' successfully! This time when I run configure for Sphinx it successfully recognizes the MySQL includes and is installed correctly!

If you have any questions let me know and I will do my best to help you!
