I'm getting this error when building:

Undefined symbols:
"_UIApplicationDidEnterBackgroundNotification", referenced from:
_UIApplicationDidEnterBackgroundNotification$non_lazy_ptr in
libThree20UINavigator.a(TTBaseNavigator.o)
(maybe you meant: _UIApplicationDidEnterBackgroundNotification
$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status

Is there a resolution for this?

Thanks,

Emery

Hello,

I am getting the same error. I guess it is because three20 kit
requires iPhone SDK 4.0? Not sure on that. Can somebody please
confirm?

Thanks

Your build settings are incorrect. Set the BaseSDK to 4.0.1 (ALWAYS
set it to the latest) and then set your DeploymentTarget to the lowest
iOS version you plan to support.

I have a problem somewhat similar.
When I compile the samples projects it works fine in the simulator but
when I switch to device the linking gives me this error
"___restore_vfp_d8_d15_regs", referenced from:
+[TTEntityTables(TTSingleton) sharedInstance] in
libThree20Core.a(TTEntityTables.o)
+[TTEntityTables(TTSingleton) releaseSharedInstance] in
libThree20Core.a(TTEntityTables.o)
+[TTEntityTables(TTSingleton) allocWithZone:] in
libThree20Core.a(TTEntityTables.o)

"___save_vfp_d8_d15_regs", referenced from:
+[TTEntityTables(TTSingleton) sharedInstance] in
libThree20Core.a(TTEntityTables.o)
+[TTEntityTables(TTSingleton) releaseSharedInstance] in
libThree20Core.a(TTEntityTables.o)
+[TTEntityTables(TTSingleton) allocWithZone:] in
libThree20Core.a(TTEntityTables.o)

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

my settings are iOS 4 for both the deployment target and the base SDK

Any idea.

The exact same thing works fin in the simulator

I believe this comes from mixing-and-matching armv6 and armv7 code.
Make sure that the Three20 projects are setting "Architectures" the
same as your project (I'm not sure, but if you're still allowing the
iPhone 3G, I believe you need to do "Standard (armv6 armv7)" rather
than just armv7, perhaps someone else can confirm or deny that).

Look like the solution indeed.
When I switched the architecture to optimized than it works.
Tested on 3GS and 4 both running iOS 4.

Thanks
