Linking libiconv on ios - ios

I am trying to use the objective-git library for an ios application I am in the proccess of developing. I am able to get the library to compile, link, and run perfectly fine in the simulator. However, when I try to run the application on an actual iPad, I get the followign error:
Undefined symbols for architecture armv7s:
"_libiconv", referenced from:
_git_path_iconv in libObjectiveGit-iOS.a(path.c.o)
"_libiconv_close", referenced from:
_git_path_iconv_clear in libObjectiveGit-iOS.a(path.c.o)
"_libiconv_open", referenced from:
_git_path_iconv_init_precompose in libObjectiveGit-iOS.a(path.c.o)
ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I believe the issue is that I am compiling the libgit2 library with a different version of iconv then the one included with ios. However, I have messed with the build script in an attempt to force it to link with the ios version, but the error persists. How should I go about properly linking the iconv library so that I can run the application on an actual device?

You need to add libiconv.tbd to 'Link Binary With Libraries' section in Build Phases.
Note: I know ObjectiveGit fixed this issue but maybe that helps to others those who are trying to use iconv in their projects.

IMFPush Bluemix not working on Swift 2.2 (i386 error)

Anyone knows how to solve this error? I can't compile my project with IMFPush library =/

There are a few questions around that seem to tackle this issue.
I would first take a look at Jordan's advice here
and ensure that the framework was added to your project correctly. Additionally ensure that the framework has been linked correctly
If neither fixes the issue then also see the answer posed by Allen and check to see if your .m file is listed under your compile sources.
That said, i386 architecture is what is used by the iOS Simulator. Do be aware that the Simulator cannot replicate push functionality, so even if you are able to compile IMFPush for it, it will not function correctly.

AFNetworking Library failing in iOS 7

Using the new iOS 7 Beta and downloading the latest version of AFNetworking, I went to File>Add Files to Project, and passed in the directory AFNetworking.framework. Now I'm getting a slew of linker errors. For a sanity check, I rolled back the commit history to iOS 6 and everything compiled successfully. Here's the log:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_AFHTTPClient", referenced from:
_OBJC_CLASS_$_CloudGlyphAPIClient in CloudGlyphAPIClient.o
"_OBJC_CLASS_$_AFJSONRequestOperation", referenced from:

_OBJC_METACLASS_$_CloudGlyphAPIClient in CloudGlyphAPIClient.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Do I need to wait for AFNetworking to get up-to-date with the next version of iOS or is this an architecture issue?
Thanks
AFNetworking compiles and loads fine for me on iOS 7. The easiest solution would be for you to set up CocoaPods, and include AFNetworking that way.
See this answer for instructions on making sure the file is included in your target. This answer will explain all the pieces of the error message to you.
iOS 7 is probably a red herring, but if AFNetworking was working before (you didn't say), you may want to file a bug report if your libraries got unlinked when you upgraded.

xcode, launching on simulator is ok but cannot archive

I am new to Xcode.
I am adding some features on the old(iOS 3.2) xcode game project. This code never touched for more than a year until I touched.
It worked fine until I tried to make an .iap file. it ran ok and all my changes didn't make any error.
So I changed target device from iPhone 6.0 Simulator -> iOS Device, and tried archive. Unfortunately it generated bunch of errors:
ld: warning: ignoring file lib/libegn_neutron_http_Release_iphoneos.a, file was built for archive which is not the architecture being linked (armv7): lib/libegn_neutron_http_Release_iphoneos.a
Undefined symbols for architecture armv7:

......similar 34 errors continued

ExitGamesShutDown(sLibraryData*) in exitgames.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
This project uses some "exitgames" library which supports social features.
Also this project have some wrapping part of "Brew" c++ codes.
I don't know which part has the problem. tried to figure out and searched a whole day but still couldn't get a clue.
Can anybody give me an advice?
Thank you.
Try running lipo -info exitgames.a from the command line, it should tell you what architectures the framework is made to support.

build error while add revmob ad in iOS app

I want to add RevMob add in my app but there are some errors
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_SKStoreProductViewController", referenced from:
objc-class-ref in RevMobAds(RevMobStoreController.o)
"_SKStoreProductParameterITunesItemIdentifier", referenced from:
-[RevMobStoreController openStoreWithITunesItemId:] in RevMobAds(RevMobStoreController.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have added StoreKit,SystemConfiguration and RevMob Frameworks already.
I am using Xcode4.3 and ios4.2
Plz help me.
Thanks in advance.
You need to add the StoreKit framework
EDIT: I see now what you mean, there was an issue with the older versions, I'm adding a link to an edited framework to solve that issue: Edited Revmob Framework
You must link against StoreKit.framework
It looks like the ad sdk you have now does not include support for use with the simulator.
-[RevMobStoreController openStoreWithITunesItemId:] in RevMobAds(RevMobStoreController.o)
ld: symbol(s) not found for architecture i386
if you get anything that mentions "not found for architecture" means revmob didnt include classes for running on simulator. You have 2 choices. look for a missing library ".a file" or only compile for testing on a device.
I've ran into an issue with the new ios6 where revmob did not support the new iphone 5 armv7s architecture.
Double check your revmob installation or try compiling to your phone instead of the simulator
When your are dropping the files manually in xcode the files are not copied to Bundle. So "SKStoreProductViewController.m" was the file not copied in the bundle so the error occurred. To resolve the error. Drag the files only .m files to Copy Bundle Resourceas shown in the image
This error can also happen if you removed a file from your project and subsequently re-created it. Sometimes Xcode doesn't automatically re-include it in the 'compile sources' box (when you click on target).
Check the box and see if all of your source files are included, if not then drag them in and rebuild.
They release a new SDK version (4.6.0) that works perfectly on older Xcode versions!
This also happens with Appirater. I was getting this message:
Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_SKStoreProductViewController", referenced from: objc-class-ref in Appirater.o "_SKStoreProductParameterITunesItemIdentifier", referenced from: +[Appirater rateApp] in Appirater.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
---To Fix---
add StoreKit.framwork in --> BuildPhases
---Under-> Link Libraries with Libraries
If you have more than one target you might need to add the
StoreKit.framwork to both Targets.
I faced similar issue and after long search and checking sample RevMob code, i found this solution, may be help others:
Under project target, select Build Settings, under Deployment, check iOS Deployment Target, change the value to 'iOS 9.0' or higher.
I hope this help.

stream windows media content to iPhone App

I am currently working on a streaming app which should receive a Windows Media Video stream. I am using libmms to encode the stream.
I took the Wunderradio as reference project. When trying to build the app I get the following error:
Undefined symbols for architecture armv7:
"_Status_SetNewStatusString", referenced from:
_report_progress in liblibmms.a(mms.o)
"_gStopFFMPEG", referenced from:
_fallback_io_read in liblibmms.a(mms.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Maybe someone knows what it means and how to fix it?
Thanks for any kind of help and have a nice day.,
MrBr.
This error occured because of not including the dependencies of the FFMPEG library into the project.
After including it the error is gone and it builds without compiler errors.
"_Status_SetNewStatusString" is not defined in the mms.c, there's a warning about it
You can delete it, it's not used in the new versions anyway.
