Problems getting iPhone example running on simulator

[Paul Barry]

I'm trying to follow the instructions here for getting Nu to run on
the iPhone:

http://floatopian.com/~reddaly/nu-iphone.html

But when I try to run the example in the simulator, it complains, I
think because the libNu.a is the wrong architecture. Here's the full
error:

Can you run Nu on the simulator?

Hi Paul,

If you didn't change the Nukefile in the iPhone directory, you
probably built the Nu static library for the iPhone device, not the
simulator. See this post for details:

Now I have this error:

Undefined symbols:
"_mach_override", referenced from:
_nu_disableNSLog in libNu.a(overrides.o)

ld: symbol(s) not found
collect2: ld returned 1 exit status

"_mach_override", referenced from:
_nu_disableNSLog in libNu.a(overrides.o)

collect2: ld returned 1 exit status

I had that error too. I "solved" it by editting the function
(disableNSLog) that was trying to call mach_override, and commenting
out the call.

I'm fairly sure that's not the right thing to do, but it got the
library compiling, linking, and running on the simulator, so I'm happy
with it for now.

Later,
Blake.

That's fine. That disableNSLog function is only to get rid of an
annoying Cocoa warning message. There's nothing in Nu that uses
mach_override for the iPhone.

In that case, here's a diff of the changes I made. :)

It seems to work for me, YMMV.
