PHP 5.1.6 recompile

[cogit8]

I want to enable MySQL support in php5 and have downloaded the sources, installed gcc and tried to run the ./configure command using the config options that appear on the phpinfo() page using --with-mysql. I have also set the --prefix option to point to the source directory.

I get a whole bunch of errors, the final one being a nofind of lex, which can be viewed in the attached file. I'm running FC6 on i386 platform. Any ideas please?:confused:

If anyone knows of an RPM of php5.1.6 or later with mysql enabled I'd be gratefule if you could point me in that direction too.

Thanks for any help.

You must install flex. If you're on Debian, do that :
apt-get update
apt-get install flex
