I've been working on getting Opa to compile under 32-bit Ubuntu 11.10. Today I found a thread on Stack Overflow where Prabhat Gupta claimed to have gotten it to compile on his 32-bit Linux machine. (The thread in question is titled Opa chat app not working)
I would have loved to ask him how he did this, but unfortunately I couldn't find any way to get in contact with him. My question: have you succeeded in what I'm trying to do? If so, how did you manage to do it? I'd really like to get Opa working on 32-bit systems, but I don't want to duplicate other people's work if I can help it.
Thanks in advance.
