Wrong ELF class - PHP extension

Question

I am trying to load a PHP extension (sdo.so) but I am getting the following error when I try to run XAMPP.

PHP Warning:  PHP Startup: Unable to load dynamic library '/opt/lampp/lib/php/extensions/no-debug-non-zts-20060613/sdo.so' - /opt/lampp/lib/php/extensions/no-debug-non-zts-20060613/sdo.so: wrong ELF class: ELFCLASS64 in Unknown on line 0

From what I've seen other people say it seems to be something to do with it being compiled on a 64bit machine and it needs 32bit. Is this the root of the problem? If so how would I compile it as 32bit in Fedora 17 as I've only seen solutions for Ubuntu and couldn't get them to work for me.

It doesn't matter on which machine you compile (the build host). What matters is for what machine you compile (the target host).

You are (apparently) running a 32-bit ix86 PHP, so you need to compile sdo.so for 32-bit ix86 as well.

how would I compile it as 32bit in Fedora 17

./configure CC='gcc -m32' CXX='g++ -m32' && make && make install

should be about it.
