I was installing Realm and imported to my project but when I run the app it shows me an error:
ld: framework not found RealmSwift
clang: error: linker command failed with exit code 1 (use -v to see invocation)
There can be multiple reasons for this issue.
To get the exact issue you can follow the below step :
Right click on error and select 'Reveal in log'. This will give you more insight about the reason of error.
One of the solution is to setting the 'Enabled Bitcode' to No. For this go to Build settings in your target and search 'Bitcode' in the search field.
I have faced this issue multiple times and one of the below solution may work for you.
After installing the pods make sure that you're opening the workspace instead of Xcode project file.
Restart Xcode
Remove derive data for your application
Reintegrate pods using pod deintegrate and pod install for your project
Reset simulator(If you are viewing the output in simulator)
Ensure proper linking of Framework in your project
Restart simulator
Clean project etc.
Hope this may help you.
I was having the same issue.
Initially, I was trying to import the files (Realm.framework and RealmSwift.framework) from download folder but then i was getting the same error like yours.
What i did then, i copied the folder containing the (Realm.framework and RealmSwift.framework) into the project folder and then i imported the files from there. That resolves my issue.
In my case, I've updated the Cocopods to the latest version (1.1.0) via this command sudo gem install cocoapods
is it possible that you are still running the .xcodeproj file. You should run .workspace file in your xcdoe
I am trying to build this xcode workspace which was built from Unity. And after modifying the project a little bit when I getting to the very end of building the project (linking) I get the Apple Mach -O Linker (Id) Error. I can't open the error tab to see what exactly is causing the error. All it says is "Linker command failed with exit code 1 (use -v to see invocation). There are also two Apple Mach -O Linker (Id) Errors which occur but I have no idea how to solve them.
Any help is greatly appreciated!
I can't expand these tabs.. this is all I get told
This is the warning tab expanded, the two Apple Mach -O Linker (Id) warnings are the same
This problem has different solutions , one of them is to set Enable Bitcode to No . ( I don't know why by default it is Yes )
This problem is a ghost like problem . Clearing Cache , Restarting Xcode , Simulator and MAC ,Ensuring proper linking of Frameworks ,Changing app Architecture or , Sometimes just doing nothing can solve this problem .
This issue was connected to "Link Binary With Libraries". I've renamed the target, and there were two .framework files for the Pods. Thus, after removing the outdated one - the issue was solved.
For me the scenario was that I removed one of the dependency in my pods which was not required, after removing it I was getting error that the same dependency not found. So I went to delete its entry from the Project >> Build Settings >> other Linker Flags and then selected the same and deleted it as shown below in the Image. After removing from the linker Flags I started getting the Apple Mach -O Linker (Id) Error? and after trying everything for a day I realised the issue lies inside the linker Flags. Where on deleting any dependecy you have to delete the other line name -framework. you can check the below image to get the clarity.
So I suggest to keep an eye on it while deleting the dependecy from the linker flags, do delete the associated -framework too which lies below the dependency name. In my case it was ObjectMapper
If you just installed/ uninstalled a pod you might want to look at this. Here's what worked for me:
First make sure you are opening the .xcworkspace file not the .xcodeproj. But this is probable not what's causing the issue.
Delete the pod that was recently just installed.
In the project directory on Xcode, open the frameworks folder and if the pod which was just removed is still listed there as one recentlyremovedpod.framework, delete it from there also. This step is what made my project compile eventually.
Another possible cause is if you rename one of your targets (why did I do that?) and you're using pods. You end up with a version of your old target name in the Frameworks folder in your main project (not the Pods project), like pods_oldtarget_framework which no longer exists.
Just delete the old version (or name your target back to it's original and delete the new one), and you should be good to go.
For me it was missing frameworks. Try searching the errors you get on Google and find out which frameworks they're part of, then import them in the Build phases tab.
I was having the same issue, and resolved by
installing the latest CocoaPods
then do pod setup
For me I had the problem because I was using Xcode 9 (beta), then I open the same project with another Xcode 8.3. To solve the problem for me just Clean then Run again.
If building on mac for ios in unity, make sure that in the build settings you disable "Metal Editor Support" under other settings for the ios platform.
I used xcode 9.3 and I got this same error. But with 9.2 it works.
The error may happen because of incompatibilities between the artifacts produced by the two xcodes. The project that threw the error included a framework built with xcode 9.2
I added libstdc++.tbd to "BuildPhases >> Link Binary With Libraries". It works for me.
How I resolved this issue:
I exit Xcode then opened my project's .xcworkspace again.
While Xcode was starting...i saw warnings...xcode is smarter enough and ask you switch to recommended settings...Tap it and let him do the changes.
(Read warning seriously and with positive mind and then you will resolve it) đ
I have been trying to find a solution to this problem for hours. Every time I try to build my project, I get the same error:
ld: framework not found SwiftHTTP
I tried following the instructions in this question but to no avail.
Are there any ideas as to what else I may be doing wrong?
As mentioned in comments, OP accessed the project via .xcproject instead of .xcworkspace, thus the framework is not loading. To solve the problem (and restore to recommended settings by Cocoapods), follow the steps below:
Close all Xcode project / workspace
In Terminal, issue pod update in the Project folder to restore the settings
After Cocoapods finished running, open the .xcworkspace and build the project
ld: library not found for -lPods-AFNetworking
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I get this error way too often and it's driving me (and the team nuts). The project was building just fine last week and I did nothing to the project in the mean time, just opened it yesterday and now I'm getting this error when building using the Debug scheme only; Adhoc builds fine. I'm running the latest Yosemite, Xcode 6.1 (but this has plagued me for many months anyway). My instructions to resolve it work occasionally, like black magic:
Clean
Restart Xcode
Delete derived data (check preferences/locations)
Pod update
Open project using the Workspace file
Delete the workspace file and run pod install
But unfortunately this time it's just not working! I've done this process over and over. I'm so frustrated with this PoS Xcode. Next step would be to re-download the project from Git, but there must be a better way! I have gone through a number of other stack overflow posts but found nothing to help (nor anything very recent). Thanks!
The same error drove me nuts for two days. I fixed through the following :
Project > Targets > Build Settings > Packaging > Product Name - Check if the product name has changed.
Also try setting the Build Active Architecture to NO in your project..
Project/Pods > Build Settings > Architectures > Build Active Architecture Only
Just delete the build folder of your project and rebuild it again. Always works for me!
I am getting an error after I put my application in an AdMob. The app was working until today. The error is the following:
ld: library not found for -lGoogleAdMobAds
clang: error: linker command failed with exit code 1 (use -v to see invocation)
How can I fix this? Thank you.
I had a similar "library not found" issue. However it was because I accidentally was using the .xcodeproj file instead of the .xcworkspace file.
Sometimes you just remove the reference of the library and add reference again.
Apart from adding the Google Mobile Ads SDK and other libraries again from scratch, I would recommend you checking the Library Search Paths. There are instances when you copy or duplicate a target, Xcode decides that it needs to escape any double quotes " with a '\'. Make sure you remove all the \âs - it should look like this -
I was able to duplicate the error, by doing prefixing my path with multiple '\'.
Select your Target, go to "Build Phases" in "Link Binary With Libraries" remove ".a" file of that library.
Clean and Build.
If error related to Cocoapods as follow:
library not found for -lPod-...
You need to check Other Linker Flags and remove it from there.
Extra Information: If you have an old project that uses cocoapods. And recently you needed to add the use_frameworks! to your podfile.
cocoapods will not add the libraries to your Other Linker Flags
anymore cause its inherited. Therefore, you may need to remove those
manually from the other linker flags which they were added before
using the use_frameworks!
For my case Xcode 7, also worked in Xcode 9.1/9.2
ld: library not found for -ldAfnetworking
clang: error: linker command failed with exit code 1 (use -v to see invocation)
set Build Active architecture Only to Yes
If error is like following
ld: library not found for -lpods
I found that a file "libPods.a" which is in red colour(like missing files) was created somehow in the Framework group of the project. I just simply removed that file and everything got fine.
EDIT: Another Solution
Another Solution that I have already answered in the similar question is in this link
goto Build Phases -> Link Binary With Libraries and remove library which show errors because that library is not available in project folder
Late for the answer but here are the list of things which I tried.So it will be in one place if anyone wants to try to fix the issue.
Valid architecture = armv7 armv7s
Build Active Architecture only = NO
Target -> Build Settings ->Other Linker Flags = $(inherited)
Target -> Build Settings ->Library Search Path = $(inherited)
Product Clean
Pod Update in terminal
ld: library not found for
It is compile time error for a Static Library that is caused by Static Linker
ld: library not found for -l<Library_name>
1.You can get the error Library not found for when you have not include a library path to the Library Search Paths(LIBRARY_SEARCH_PATHS)
ld means Static Linker which can not find a location of the library. As a developer you should help the linker and point the Library Search Paths
Build Settings -> Search Paths -> Library Search Paths
2.Also you can get this error if you first time open a new project (.xcodeproj) with Cocoapods support, run pod update. To fix it just close this project and open created a workspace instead (.xcworkspace )
[Vocabulary]
As for me this problem occurs because i installed Material Library for IOS.
to solve this issue
1: Go to Build Settings of your target app.
2: Search for Other linker flags
3: Open the other linker flags and check for the library which is mention in the error.
4: remove that flag.
5: Clean and build.
I hope this fix your issue.
In my case there was a naming issue. My library was called ios-admob-mm-adapter.a, but Xcode expected, that the name should start with prefix lib. I've just renamed my lib to libios-admob-mm-adapter.a and fixed the issue.
I use Cocoapods, and it links libraries with Other linker flags option in build settings of my target. The flag looks like -l"ios-admob-mm-adapter"
Hope it helps someone else
Simply, GoogleAdMobAds.a is missing in project target.
For me it was libAdIdAccessLibrary.a Please check attached screenshot
In the case of ld: library not found for -{LIBRARY_NAME} happened because the library file(s) is not existing.
Check the library path on your application targetsâ âBuild Phasesâ
Library Search Paths tab.
The library file(s) path must be according to the real path for example if your file(s) in the root of the project you must set the path like $(PROJECT_DIR)
I know this is a bit old, but I just hit a similar issue and running 'pod update' fixed this for me. My library error was with AFNetworking...
Just be careful doing pod update if you don't use explicit versions in your pod file.
This error is very weird.
I had this error with -ldAfnetworking and I only copy my project in other path and works.
I tried renaming my build configuration Release to Production, but apparently cocoa pods doesn't like it. I renamed it again to Release, and everything builds just fine.
#raurora's answer pointed me in the right direction. I was including libraries in my "watchkitapp Extension/lib" path. In this case, the Library Search Path needed to be escaped with a '\', but the linker didn't seem to understand this. To fix / work-around the issue, I moved my lib path up one level so it was no longer in a directory that contained a space in the name.
I just update the pod file 'pod update' and it start to work for me normally.
Running 'pod update' in my project fixed my problem with the 'library not found for -lSTPopup' error.
Remarking Trevor Panhorst's answer:
"Just be careful doing pod update if you don't use explicit versions in your pod file."
Easy solution. Here's how I'd fix the issue:
Go to the directory platforms/ios
Then, execute the command pod install
That's it. This should install the missing library.
Cleaned Build Folder
Restarted XCode
Went away...
I was getting similar bugs on library not found. Ultimately this is how I was able to resolve it
Before starting with Xcode Archive, used flutter build iOS
Changed the IOS Deployment Target to a higher target iOS 11.2 . Earlier I had something like 8.0 which was giving all the above errors.
Made sure that the IOS deployment targets in Xcode are same in the Project, Target and Pods
I was also facing the same issue and spent more than 24 hours to solve this, I tried everything from the above solutions but what finally works for me is
Build settings -> Select Target
Basics
User-defined
Change the VALID_ARCHS to arm64
Dude you need a reinstallation.
Delete simply "rm -rf" pods.
Install Pods "bundle exec pod install"
Works well then.
the same here, but in my case was resolved with answer the kenorb
