Re: [reSIProcate] rendIt on osx

[Scott Godin <sgodin@xxxxxxxxxxxxxxx>]

Hi Jason,

Welcome back from the dead!  : )

RendIt was contributed by Logitech.  It was used solely in a unix environment.  When I added the code the SVN for them, I got things to build in Windows as well.  I think it's safe to say that it hasn't been tested under OS/X yet.  I think you are on the right track with using "fdset" (also used under Windows) - but I can't explain why you are having trouble binding to port 5060 - other than it is potentially in use on your machine (I'm also assuming that the IP printed in the logs is correct: 192.168.0.129).  Is it also binding to the same interface using IPV6?

As for "event" - the intention was to have the code pick the best method based on the compiler options and OS: this means "epoll" for OS's that support it and FdSet for those that do not.  Here are some docs from testStack.cxx:

    event       Each stack runs in its own thread, and that thread

                is an interruptable event-loop based thread. The specific

                type of event-loop depends upon the underlying platform

                and how you compiled the stack.

    epoll       Like "event", but specifically uses the epoll implmentation.

    fdset       Like "event", but specifically uses the FdSet/select

                implmentation.

Hey guys (I'm back from the dead),

I'm trying to get rendIt working on osx. I'm running into problems
with what I think is the code related to epoll - which is not
available on OSX. rendIt has likely only been tested on linux in the
past.

RendRunner.cxx is instantiating a resip::EventStackSimpleMgr with
implName = "epoll". I thought that I could work around this issue by
changing implName to "fdset". However, when I do this, here's what I
see when the sip stack tries to bind to the UDP port on 5060.

Any ideas what is going on here?

Also, what is the implname = "event" supposed to mean? Is this
unsupported? It looked to me like maybe it was intended to support
libevent on other platforms but I can't find code referring to it
anywhere.

Thanks
Jason
