BOOST Runtime - Linux 2.6

Attempting to recompile boost to work on my Cyclone 3LS200 NIOS 2 Linux configuration build. However, I'm having a few problems with BOOST that I was hoping someone may have encountered and could direct me.

1) epoll: Function not implemented

Attempting to use the ASIO functions within boost, I'm receiving errors about epoll not having implementation. A strings on my provided libc.so.6 provies:

epoll_wait

epoll_create

epoll_ctl

I believe this proves that only the header file is compiled into the library. How do I go about getting the implementation in the library?

2) Threading - This I have to get further information from. Standard small program, I can execute threads, but in my complex programs, the program halts during thread creation. I have to look further into this one and attempt to get some debugging tools like ldd/ptrace on the system.

Anyone had experience building against the newer BOOST builds? Thanks!

Linux 2.6 - Built from the nios2-linux-20100621
