cgi-bin crashes on 64bit ubuntu

HI,

i have a web app cgi-bin, that i need to get working on a 64bit Ubuntu 14.04 server.

i’ve followed the steps to install the libs as per http://documentation.xojo.com/index.php/System_requirements

and i can see in the apache error.log

“end of script output before headers”.

how do i work out why its crashing?

please excuse the noise!

it was the 32 bit libmysqlclient that was missing.
