SmartConfig iPhone app source code does not compile

Jackson Keating

Other Parts Discussed in Thread: CC3200

I've attempted running the "Wifi Starter" iOS source code from Xcode 5 and I get the errors listed at the bottom of this post. I think the root problem seems to be the first warning. Apparently Xcode 5 is ignoring the FirstTimeConfig library because it is missing a required i386 architecture. I'm not sure what this means. Has anyone else successfully launched the application from Xcode? Has anyone else seen this problem? I'm running Mavericks.

Just trying to get some visibility on this. Thanks.

Hi Jackson,

Do you only get this issue when trying to use the iOS simulator, but it works fine on your iOS device?

If so, then this is due to the SimpleLink library not being compiled as a Universal library, so it will only run on a device and not on the simulator. This is very annoying, as it makes it difficult to test apps with the various screen sizes. This was something I requested previously when working on the CC3000, as to create a Universal library should only take a few minutes work to do. See my post here - http://e2e.ti.com/support/wireless_connectivity/f/851/p/298073/1153347.aspx

As for your other questions, yes I have SimpleLink working with Xcode and have it integrated with my iOS App, everything works great. You just need a device to make it happen.

Glenn.

Thanks Glenn. Good to know I'm not the only one having this issue. I'll try compiling it to my phone instead. It really is too bad that we can't use the simulator. It's the most effective way to troubleshoot by far. And smartconfig is going to have to be an integral part of most iOS applications that interface with the CC3200.

TI? Is there any update on this? Are you planning on providing support for this in the future?

Hi Glenn,
unfortunately I have the build issue also with the iOS Device. Here the error message:

Undefined symbols for architecture arm64: "_OBJC_CLASS_$_ZBarReaderView", referenced from: objc-class-ref in SmartConfigAppDelegate.o

I'm using Xcode 6.1.1 and Yosemite.
Has anyone else seen this problem?

Gabriele.

Hi Gabrielle,

This looks to be an Xcode config issue, check out this post - http://stackoverflow.com/questions/19213782/undefined-symbols-for-architecture-arm64

Hi, yes the solution described in the stack overflow post work fine.
However, just some minutes ago, I received an email notification from Apple Dev Portal that inform that starting 1th February 2015 all apps have to be submitted compatible with 64bit architecture. So TI should solve the problem and compile the SimpleConfig lib also for 64bit.

Are you saying that the libFirstTimeConfig.a is not compiled to 64 bit?

If so, then this is definitely an issue, that needs to be resolved ASAP, as per Apple announcement - https://developer.apple.com/news/?id=10202014a

If instead it is the ZBarReaderView library (libzbar.a), then this will need to be resolve by the developers of ZBar, which I believe is an open source project found here - http://zbar.sourceforge.net/iphone/sdkdoc/ (or you could build it in 64 bit yourself)

I just came across another StackOverflow which should help - http://stackoverflow.com/questions/21140492/zbar-with-ios7-and-xcode5-compiling-error-libzbar-a-architecture one of the links may have a 64 bit compiled version.

Alternatively, the ZBarReaderView is only required if you are using the QR reader, and perhaps ZBar can be done away with completely if you are not using it (I have removed it from my app)

If you are using it, then perhaps consider implementing the native support for QR Reading, now found in the AVFoundation - http://www.appcoda.com/qr-code-ios-programming-tutorial/

Try to use #if !(TARGET_IPHONE_SIMULATOR) to skip every code using FirstTimeConfig or CCX3000 headers when building on simulator. That works for me just run and test smart config functionality on real devices and also it won't effect any other parts of project. I think this is the simplest way to do it. TI smartconfig lib won't work on simulator.

That's a good option for workaround. I preferred not littering my code with these checks and just created a separate target and scheme for my simulator testing. I'm creating a Swift application, so I ended up creating a "mock" FirstTimeConfig.swift class that stands in for the real FirstTimeConfig header. That swift class is only assigned to my simulator target. Works well, and I didn't have to change the rest of my source code.

Hello all,
trying to revamp this thread.
One of our developers states that since the smartconfig library for iOS is provided only in 32bit flavor, he is not able to link it in his current iOS project, that obviously is targeted at 64-bit only since Apple claimed months ago that 32bit applications will not be supported anymore.
Is it possible to use the current iOS 32bit smartconfig library for iOS8 and iOS9 with some workaround?

Hi All,

The Smart Config library inside the iOS Wi-Fi Starter app is already compiled into 64 bit, even though the app itself is only running in 32bit. This means your development based on the Smart Config library will comply with Apple's 64-bit requirement.

Will TI update this smart app for 64 bit ? I am not able to get this to work having the same errors...

0 Mark Beaty over 9 years ago in reply to Ryan Summey

Intellectual 380 points

As Victor said, the library included with the TI sample app already supports 64bit. I have had it working fine for months. If you are getting the same error, you are most likely trying to run on the simulator, which is not possible. You will need to run on a real device.

Hi Ryan,

Please share the error information you run into. TI has no plan to update this app at the moment.

I am able to get this to finally build and deployed to my iPhone 6 plus when disabling bitcode in the build options . I do not know if that impacts anything or not. The whole project is riddled with warnings.

ld: '/Users/partialdata/Desktop/WiFi-Starter-App-iOS-Source-1.0-zip/Source/SmartConfigCC31XX/libFirstTimeConfig.a(FirstTimeConfig.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture armv7

Victor, can you please confirm that the library has been tested and verified to work on iPhone 6, 6 Plus, 6s, and 6 Plus with the latest version of iOS 9.x. The fact that I have seen 2 reports on this forum of problems with SmartConfig once moving to iPhone 6 and iOS 9 has me worried, because I will soon be upgrading my app to run on the iPhone 6/6s series phones and iOS 9.x as well. I need it to continue to work. Thank you.

Hi Ryan, Mark,

The existing app from the app store definitely works fine with the latest iOS9.
To resolve this compiler error, please disable the ENABLE_BITCODE option in the project environment. See the external topic here: stackoverflow.com/.../impact-of-xcode-build-options-enable-bitcode-yes-no
