CoreLocation Undefined symbols for architecture i386
There are two things you need to do: 1 ) Make certain your target membership is checked on for CoreLocation.framework, like this: 2 ) Make certain that you have done an "#import <CoreLocation/CoreLocation.h>" at the top of your ViewController.m file.

Undefined symbols for architecture i386 linking facebook sdk
The error you are seeing is from the linker. When you compile your code, the compiler can find declarations for all the functions that you need, because you're including the facebook header (facebook.h). But when it comes time to link your program, the linker tries and fails to find compiled versions of those facebook methods. You need to bring the facebook SDK into your project and link against it. The way I'm going to recommend linking against the Facebook SDK is actually one I haven't tried before, but it looks like the simplest way to get your project building: Download and install the FacebookSDK framework from here. Drag the FacebookSDK.framework bundle, which will end up in ~/Documents/FacebookSDK into your Xcode project. When given the option, choose not to "Copy items into d

Hopefully you've solved this by now. The issue you were running into is that you don't have GLKit.framework linked in your build phases. You should check out the Getting Started page for the full list of setup instructions, but the relevant step is below. Open the Build Phases tab, and within Link Binary with Libraries, add the following frameworks: AVFoundation.framework CoreData.framework CoreLocation.framework CoreText.framework GLKit.framework ImageIO.framework libc++.dylib libicucore.dylib libz.dylib OpenGLES.framework QuartzCore.framework SystemConfiguration.framework

What does undefined symbols for architecture x86_64 mean in C?
You need to include #include<stdlib.h> file in your code for delay() function, its not defined in stdio.h But I suggest don't use it, instead use what most Unix based operating system suggests unsigned int sleep(unsigned int seconds); function from #include <unistd.h>. read don't use delay()

Cuda - Undefined symbols for architecture x86_64 OS X
nvcc treats .cu files as C++ and you have your host code in .c files (i.e. in C, not C++). The easiest solution is to simply rename your .c files to .cpp and treat your app as a C++ app instead of C. You could also declare kmeans() as extern "C" {...} to force the compiler to use a C binding instead of C++ binding for the function, but then you'd have to do that for every future function which is probably unnecessarily inelegant.

Cocoapods - Flurry & TestFlight - Undefined symbols for architecture
I've found that can be few reasons of this issue: libPod.a not included in "link binary with libraries" (try to remove reference and add again) Compiler can't find library. Strange behaviour, try to write path to libraries using ${PODS_ROOT} at "Library search path". ($(PODS_ROOT)/TestFlightSDK for example) Compiler can't find header. try to write path to headers using ${PODS_ROOT} at "Header search path". Hope that this is helpful.

Undefined Symbols for architecture x86_64: Compiling problems
There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't. Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly, void Similarity::readData(Scanner& inStream){ } not void readData(Scanner& inStream){ } etc. etc. The second one is a function called readData, only the first is the readData method of the Similarity class. To be clear about this, in Similarity.h void readData(Scanner& inStream); but in Similarity.cpp void Similarity::readData(Scanner& inStream){ }

Xcode build failure "Undefined symbols for architecture x86_64"
It looks like you are missing including the IOBluetooth.framework in your project. You can add it by: -Clicking on your project in the upper left of the left pane (the blue icon). -In the middle pane, click on the Build Phases tab. -Under "Link Binary With Libraries", click on the plus button. -Find the IOBluetooth.framework from the list and hit Add. This will make sure that the IOBluetooth.framework definitions are found by the linker. You can see that the framework is a member of your target by clicking on the framework in the left pane and seeing the framework's target membership in the right pane (note I've moved the framework under the Frameworks group for organization purposes):

OpenCv Makefile Undefined symbols for architecture x86_64 error
You almost have it right: You just need to add the output filename (program name) to the linking step: main: $(DEPENDENCIES) $(CC) $(ARCH) $(LDFLAGS) -o $@ $(DEPENDENCIES) # ^^^^^ Hehe you just forgot that. If you had looked at the command-line output you'd have seen that it prints out: gcc -arch x86_64 /opencv-ld-flags/ -o main.o color.o So all it's doing is trying to OUTPUT to main.o contents of color.o where as what you intend is: gcc -arch x86_64 /opencv-ld-flags/ -o main main.o color.o The $@ will evaluate to the target file (in this case main) on the left side of the colon (:) in the build rule statement. Cleaner make file CC = g++ # CPPFLAGS are different from CFLAGS # keep CPPFLAGS name only for pre-processing flags CFLAGS = `pkg

Getting "Undefined symbols for architecture armv7" while using extern to make variable global
extern means: "this thing is defined somewhere else" So, you aren't declaring a global variable. You're just saying that someone else is and that you want to use it. So when the compiler tries to find it and comes up blank it tells you it couldn't find the definition. Not that you should be trying to use a global for this, you shouldn't, but it would be done using static. You should make the loggedIn flag an instance variable and provide proper, read only, access to the value. This means publicly read only, but privately writeable. So that the status can only be changed inside the class (as a result of loginViewController:...). So, in the .h file you would have: @property (assign, nonatomic, readonly) BOOL loggedIn; And then in the .m file: @property (assign, nonatomic, readwrite)

XCode linking error to cached library information without being called (Undefined symbols for architecture)
I resolved my own problem, or rather, the issue was with the black box of a library that I was including. From the command line performed the following command in a terminal window: grep SampleMarkView myLib.a Which resulted in: Binary File:myLib.a matches I talked to the person who created the library and they sent me an updated version that didn't cause the problem - I guess they had old references in their code. So at the very least I hope this post provides a list of various things to try if you are having a library referencing problem!

How to solve the architecture i386 linker error while using GPUImage?
GPUImage framework is not added to your project Target. Adding the framework to your iOS project Start by dragging the GPUImage.xcodeproj file into your application's Xcode project to embed the framework in your project. Next, go to your application's target and add GPUImage as a Target Dependency. Finally, you'll want to drag the libGPUImage.a library from the GPUImage framework's Products folder to the Link Binary With Libraries build phase in your application's target. And of course : #import "GPUImage.h"

You could conditionally compile the code using that framework: #if !TARGET_IPHONE_SIMULATOR // Code using "SomeComponent" that should be compiled for iOS device only ... #endif Alternatively, you could "weakly link" against the framework (as described in "Using Weakly Linked Classes in iOS" and check the availability of the class at runtime: if ([SomeComponent class]) { // Create an instance of the class and use it. } else { // Alternate code path to follow when the // class is not available. }

XCode 5 GM linker error: too many compact unwind infos in function anon for architecture i386
Workaround: Build for device. Not so much of a fix, but try building your app for a device rather than simulator. Might be related to the introduction of 64-bit. I can archive my app, but when I try to build/run for simulator, it fails at linking with the same error you're receiving. To be clear, I'm also using cocoapods.

Why does #importing the .m file fix an Undefined symbols error?
I think you should only import header file . You are getting the above error when the .m file is not included in to your class . This may happens when your .m file is not in the compiled sources under build phases. first see that whether it is in compiled sources . then try out with importing .h file .

Using libavformat in C code, undefined x86_64 symbols
The undefined symbols error occur because you do not tell the linker to link against libav. Try using gcc -Wall -o base -lav base.c. The -l flag tells the linker to use the libav library. Note that the lib part is left out when using the -l flag!

Diagnosing "contains undefined reference for architecture" at linking phase
Been fiddling all day, found it. The method that the link is complaining about has this in it: qt_mac_execute_apple_script This method does not exist in qt5. Also, earlier in the problematic file, I have this: extern bool qt_mac_execute_apple_script(const QString &script, AEDesc *ret); if i comment these lines, the error goes away. So basically, a very bad compiler error for a missing symbol – because the compiler wasn’t nice enough to point out what the actual problem is beyond the vague architecture statement; probably made worse because I’m building my application statically coupled with the extern.

matlab mex clang C++11 thread -> Undefined symbols error
The error is due to compiling against -stdlib=libc++ but linking against -lstdc++. You can fix it in one of two ways: Fix it in mexopts.sh. The most drastic and effective solution. Located in ~/.matlab/${MATLAB_VERSION}/mexopts.sh, this determines all compiler options. Simply find/replace all stdc++ to c++. Patchwork solution: Simply add -lc++ to the tail end of CXXLIBS. I'm not sure what the effect of linking against multiple versions of the standard libraries is, but it seems to work. In your mex invocation, add the argument CXXLIBS="$CXXLIBS -lc++". As a secondary issue, I believe you're completely overwriting the value of CXXFLAGS; you must escape the $ symbol as I did above with the libraries.

Why do I get "Undefined variable" when trying to resolve a multi-dimensional array?
I think the $$ notation only accepts a variable name (ie. the name of a variable). You are actually trying to read a variable named "$GLOBALS[ 'a' ][ 'b' ][ 'c' ]", which does not exist. As an alternative ($GET_VARIABLE seems to be your input string), you could try this: $path = explode('.', $GET_VARIABLE); echo $GLOBALS[$path[0]][$path[1]][path[2]]; Wrap this in a suitable loop to make it more dynamic; it seems to be trivial.

Undefined Symbols for custom C++ classes in Xcode 4.6.3. Works in Xcode 4.5.2
I had faced similar problem, and here is what I did to solve: 1 - Specify -fobj-arc flag against respective mm file in Build Phases section (this is optional and may not work always) 2 - Ensure that wherever .mm (or it's .h file) is included, that source is also marked as Objective-C++ Source and vice versa. I know it's bit tricky to do trial and error, but the basic principle is to maintain same compilation options for the file tree being included.
