ooh323, oh323 and h323

I could compile Asterisk ooh323 and H323, However, I do not know how to compile or load oh323(Asterisk oh323) if I have already compiled H323.
I followed this link:

astrecipes.net/?q=astrecipes/com … with+oh323

when cd to the open323 dir, I could not even run: ./configure

I like to try different H323 channel drivers.

Thanks for any input,
