[Iometer-devel] Re: Building error of IOMeter in Linux.

[Wolstenholme, D. E <dan...@in...>]

But I am using Xscale!
Let me work on it a little more, and I'll send you the patch when it's
ready.

I'm having another problem trying to get this to work (on an IOP331
Xscale system).  After I get it compiled, and try to run it, it fails
with the error:

=3D=3D=3D> ERROR: Getting host name for "glamdring" failed.
     [PortTCP::Create() in IOPortTCP.cpp line 260]
     errno =3D 11
*** Could not create a TCP/IP Port. exiting.....

It seems that it's using the (now obsolete) "gethostbyname" function to
try to do a DNS lookup of the hostname.  The problem here is that this
system is on a private network with no DNS, so of course that fails.
I'm not sure why dynamo isn't just using the machine's native IP address
instead of trying the backwards way of doing a DNS lookup.

pls ignore that error.

u do not need that kernel module in 99% of the time. the sole purpose of
that module is for cpu like xscale.

of course, if you give me the patch, i would like to add to iometer
svn. ;)

thanks!
