I'm happy to report that thanks to APR, I can now successfully cross-compile
my server under Win32 and Unix, and run it on both! I can't thank you all
enough for your wonderful library!
So now that I'm running, however, I'm encountering some issues. The first
is as follows: how do I enumerate the IP addresses of the server? My basic
algorithm is as follows:
# // Get the machine's DNS name and look up its IP address(es)
# char hostName[APRMAXHOSTLEN + 1];
# apr_gethostname( hostName, sizeof(hostName), pool );
# apr_sockaddr_info_get( &sockAddr, hostName, APR_INET, 0, 0, pool );
# do
# {
# // Walk across the linked-list of addresses and output
# char* ip = 0;
# apr_sockaddr_ip_get( &ip, sockAddr );
# cout << "Found IP: " << ip << "\n";
# }
# while( sockAddr = sockAddr->next );
On Win32 this finds all network adapters, but under Unix (Fedora Core 2)
this only finds the loopback address (127.0.0.1).
Any suggestions on how else to algorithmically identify the local machine's
IP addresses? This technique kinda works on Win32, but feels kinda flaky
(and is flaky on Unix). Is there any better approach to finding local IP
addresses?
And for reference, here's my /sbin/ifconfig output:

PS: I gave up on the UTF-8/16 conversion using APR and just wrote my own
converter. If anyone is interested in the code, I'm happy to share.
