- Organization: Sweeney Design
- Reply-to: "Chris Garry" <cgarry at sweeneydesign dot co dot uk>
eCos updated from CVS today.
Hardware: E7T
Template: net
'Samsung KS32C5000 ethernet driver package' added
'INET support' disabled in FreeBSD networking stack
'INET support' disabled in Basic networking framework
The build fails with:

So I tried a simple fix:

But then the build fails with:

Should it be possible to build eCos with INET disabled?
