[Freeswitch-users] run error after building in vs 2008!

[Peter Olsson]

I also came across this error today on a Windows 2003 server (same issue as XP). For now I've commented out the call to inet_ntop(), but I think the code below probably could be used - I Googled it. I'll try to find some time to get it working within FS. I think there are still some XP/2003 boxes out there, so it should be worth fixing.

    fix switch_get_addr to work with v6 properly

to fix ipv6 support.  We welcome a patch to restore xp support.

Oh yeah - looks like that call is not supported in older os like XP.

FreeSWITCH does support XP though - http://wiki.freeswitch.org/wiki/Users_Guide_Introduction

So I don't know.

ya I've got that in place
but as I searched the web they say it's related to windows version (xp vista . . .)
