Wow.  Thanks for the quick response.

I'm using the 2.0 release of eCos, not the latest from CVS although I can easily switch if you think it may be part of my problem (or future ones...)

My exported config is attached.

Thanks,
Chris

I'm new to eCos and am trying to get some simple networking capabilities into an application that I've inherited.  The eCos configuration I have appears to have the networking package included and yet when I attempt to link my application against the eCos libs I get several 'undefined reference' type errors.  In particular:
 
   undefined reference to 'init_all_network_interfaces'
   undefined reference to 'eth0_up'
   undefined reference to 'eth0_bootp_data'
   undefined reference to 'inet_ntoa'
 
It's some simple ftp client side stuff that is generating these errors but all I'd really like to be able to do is create and read data from a socket.
 
I'm using the eCos Configuration Tool Version 2.11 in Windows XP and everything in the configuration builds fine.  In the configuration view I have 'Basic networking framework' with 'INET support' checked under it, and 'OpenBSD TCP/IP Stack' and 'FTP client' also there.
 
I've tried to provide the summary of what I'm doing but please ask if there is something I've left out that would be valuable.  I've searched the archives and google'd a bunch but I'm unable to figure out a simple explanation for why the networking stuff doesn't seem to make it into my config.
 
Thank you,
Chris
