I'm trying to add the hypen library to my Xcode iOS project and it has 4 files: hyphen.c, hyphen.h, hnjalloc.c, hnjalloc.h. I dragged them to my project and hit build, but I'm getting undefined symbols for architecture i386 errors. Am I supposed to take any other steps besides dragging them to my project?
Make sure you've added them to the build target - including a file into the project without including in the build target can easily cause this error.
right click on the Source folder (top left where all the folder are) and check add. Then choose the files you wish to add. I tried drag&drop had problems with linker.

I am new to Xcode and want to add and use framework which I have taken from internet but
when I add it to my products folder by right clicking on products and using add new files it
runs fine and when i use my project's project.app file on my mac or on any other mac it
gives me dyld error that the bundle image not find. And when I use bundle image in my
framework folder its give me ld error that bundle not found help please.
ld: framework not found SMS-Bundled
Command /Developer/usr/bin/clang failed with exit code 1
*updated
when i add my framework to framework folder now its giving me error at run time...

(In Finder)
Go to the folder where your custom framework is. copy the framework. Now go to your project's folder. Create a new folder called Frameworks, paste the custom framework inside this folder.
(In Xcode)
Drag the custom folder FROM finder to the Frameworks folder on the project explorer (where all the rest of the frameworks are)
Now select your project, go to Build Settings, scroll down to "Framework Search Paths" field, double click the value to open it, press the + to add a new path, write ./Frameworks as the new path.
From now on if you want to add other private/custom frameworks all you have to do is copy them into the created frameworks folder, and simply drag and drop it into the xcode frameworks folder. (You must drag it from the project framework folder in finder to the framework folder in xcode).
PD: You don't necessarily have to name this folder frameworks, it can be whatever, just make sure to change the Framework Search Paths accordingly.
In your project build setting, under "framework search paths" mention the path of the framework.
This will resolve your issue.
Working on my iPhone app and trying to build for debug and I get "106 duplicate symbols for architecture armv7"?
I am using the .workspace file because I am trying to use CocoaPods. If I don't use the .workspace and instead use the .xcodeproj I don't get the error, but then I get missing -lPods .
In my project I have the following targets in the Project Navigator.
Pods (blue icon)
MyProject (blue icon)
Restkit.xcodeproj (blue icon)
... all my files
The issue is that Restkit is making reference to "AFHTTPClient.h" and all the other AF code, but I included it via CocoaPods. I tried deleting the AFNetworking folder from the RestKit library, but apparently the Restkit library can't find the Pods version of AFNetworking?
Is there a way to get RestKit to use the Pods version? If not how do I go about removing Pods from my project?
There is a line in one of your .h files where your wrote
#include "___.m"
instead of
#include "___.h"
So I fixed it. After removing the RestKit version of AFNetworking, from the vendor folder, I added it back by dragging into Xcode. It asks which project I want it used/copied to and this time I selected RestKitTest (or whatever the RestKitTesting is named). It works now. Maybe I selected both RestKit and RestKitTest before, which was wrong?
I also came up with same error. Generally this kind of error occurs due to duplicate classes and xibs in project folder. For Example in my project I had these classes twice ServiceRequest.h/.m. Get rid of duplicate ones and you are good to go.
In Build Phases -> Compile Sources, make sure you don't have the same file added twice.
"Duplicate symbols for architecture" issue occurs in two situations:
You added a .m file twice into your project
You're using a static library (.a file) which already includes some classes that you include into the project.
For fixing any of those cases, check the linker error and look for the .o files that are duplicated (sample: Reachability.o).
Then go to the build phases -> compile sources and search the specified files, if any one appears twice delete one of them, if only appears once it means that the file is also included in one of the static libraries added to your project. Delete it from your list of sources to be compiled and try again.
I saw this error when, I did drag and drop my calabash framework onto xcode and selected add to targets option in the window thats shown. Basically there were two references to files added
I had to remove the calabash framework manually
Right way of doing it
copy to calabash framework to project directory
then go to xcode project
Choose target -> Build phases -> Link Binary With Libraries and add the frame work using + button
I have noticed that duplicate symbols are caused for Google analytics after installing cocoaPods as well. Once I removed one of archives, either libGoogleAnalytics_debug.a or libGoogleAnalytics.a duplication has gone. But obviously if I removed debug one I will not be able to run os simulator and vica versa. I know its not the solution, but at least it could give an idea what could be a solution. Will come back to this thread if I will figure out how to have both a files in this case.
Edit:
I was able to solve the issue by upgrading from G analytics version 2 to 3. It has only one library file and I guess this is the reason why we don't get duplicated symbols anymore. I hope it makes sense.
I want to use CorePlot.framework in Mac OS X. However, I cannot install it correctly though it has costed me several hours.
I downloaded it (0.4 version) from google host site, and have tried to put CorePlot.framework in "/Library/Frameworks/" or some other custom places.
I also have added it into "link binary and libraries". unfortunately, the compiler always cannot find "" .
Any one who have some experience can give me some advice to install and use it?
If you check the readme files, you can find the instructions as follows:
Copy the CorePlotHeaders to your Xcode project
Copy libCorePlotCocoaTouch.a to your Xcode project
Add to Other Linker Flags in your target build settings: -ObjC -all_load
Add the QuartzCore framework to the project.
To follow these instructions, create a new blank project and copy the folder (drag and drop) CorePlotHeaders into Xcode. When prompted, be sure to check "copy these files/folders to the source directory".
Next drag the libCorePlayCocoaTouch.a library in the same manner (again, select the checkbox). You should now have the .h files and the .a included in your project.
Now, select your project and choose the "Target" and in the 3rd tab "Build Settings" search for "Other Linker Flags" and add -"ObjC -all_load" without quotes.
Finally, add the QuartzCore framework to your project and you're done.
I've been working with CorePlot today and am rather impressed with it so far. It's not 100% comprehensive but it's good enough for what we need. If you get stuck, be sure to follow the readme instructions and double check everything is setup as needed. I didn't struggle with getting it set up unlike some other libraries so hopefully you should be able to get sorted with minimal fuss :)
I dragged skype fromwork into my frameworks folder and then imported <Skype/Skype.h>. When I run, it gives me this error:

Try setting the "Library Search Path" build settings for your project.
In Xcode 4.x:
You need to drag the .framework from the Project navigator to the Copy Files build phase.
In Xcode 3.2.x:
Choose Project > New Build Phase > New Copy Files Build Phase
In the Destination drop down box select Frameworks
Close the Copy Files Phase Info window to return to the Xcode main window
In the Groups & Files pane expand Targets > YourApplicationExectuable, where you should now see a Copy Files entry
Still in Groups & Files pane drag your framework into the Copy Files entry
Recompile
If you don't do this, the framework will not be actually copied into your application bundle, so it will not be found when your app tries loading it into memory.
Just as a side note, I spent months trying to track down an answer to this problem, always seeing this answer but never being able to get it to work.
MY MISTAKE:
The "Copy Files" build phase is not shown by default. I was seeing the "Copy Bundle Resources" phase and wrongly assuming that was where I needed to list the framework.
At the bottom of the Build Phases pane click on Add Build Phase. "Copy Files" is listed there.
Doesn't work for me. I had to make a link to the framework in the ~/Library/Developer/..../Debug/../Frameworks for it to work.
I am trying to add a dependent project in XCode 4. The link to the project is this: https://github.com/jverkoey/ObjQREncoder
The author described a way to add this but it's for XCode 3. I am trying to add it to XCode 4.
I dragged the project inmy frameworks, then went to Targets and QREncoder in Target Dependencies. Then I added libQREncoder.a in "Link Binary with Libraries". Then I added this for header search path "src/Classes".
When I include "QREncoder/QREncoder.h", it gives me this error: file://somePath/FINALQRAppDelegate.m: error: Lexical or Preprocessor Issue: 'QREncoder/QREncoder.h' file not found
This is how my project is set up:
FINALQR is my project to which I am trying to add the dependency and the dependency project is in src.
Thanks.
The problem is it doesn't recognize the QREncoder class.
Only Xcode 4 workspaces benefit from shared build folders across multiple projects. From the main menu, select File > New > New Workspace... Save the workspace, then drag your subprojects into its Project navigator panel.
Be careful where you place them (make sure you're not making one project a subproject of another within the workspace) so that they're all top-level projects within your workspace. This will cause them to share the build folder and automatic dependency detection should work.
Unless, of course, you have custom search paths set in your targets' build settings. :-)
I think your problem is you need to set the following as your search path:
"$(SRCROOT)/src/Classes"
not
"src/Classes"
If you already have an Xcode4 project, you should be able to drag QREncoder into it as a subproject, as I think you have already done, and then add the .a file, also as you've done.
