Linker Error : Library not found

[wm-j-ray]

IOS 9 Target, Xcode beta 3 Build: 7A152u, simple Cartfile:

github "ReactiveCocoa/ReactiveCocoa" ~> 2.5

Library builds fine in Carthage/Build/IOS -> ReactiveCocoa.framework which is dragged and dropped into Target : Link With Libraries

RunScript:

/usr/local/bin/carthage copy-frameworks

InputFiles:

$(SRCROOT)/Carthage/Build/iOS/ReactiveCocoa.framework

Yields This:

ld: framework not found ReactiveCocoa
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Question: Any idea where I'm messing up?

ReactiveCocoa.framework which is dragged and dropped into Target : Link With Libraries

From the error, it sounds like the problem was here. Maybe double check that it was added to the right target?

[wm-j-ray]

Thanks,

I'm trying to run Colin Eberhardt's tutorial from here: http://www.raywenderlich.com/62699/reactivecocoa-tutorial-pt1 but without the Cocoapods...

Here's what I've got...

[mdiep]

Are you getting the ld error when the copy-frameworks script is run?

[wm-j-ray]

I don't think it makes it that far in the build process. It's confusing me. So I ran an experiment to verify that the script was indeed executing.

I removed the library, got rid of the input file setting for the script, and replaced the copy-frameworks with a simple echo to see if the script ran (checking View:Navigators:Reports Navigator). Simple script, one line - echo "Script ran". Built and ran fine, and the echo shows up on the report navigator. (I thought that maybe my bin/sh got screwed up some how, but alas, no...)

Then I put everything back in, the library, the input file and added a 2nd line to the script (copy frameworks), and left the echo in at line 1, so now I have a simple 2 line script. Cleaned.

When I tried to build I almost immediately got the framework not found abort and in the Report Navigator, there is no echo statement. (So I am assuming she didn't make it that far into the build)

This is the freshest version of xCode under IOS 9. I'm a little perplexed.

What is the value of FRAMEWORK_SEARCH_PATHS? It seems that the setting is not correctly set up.

[wm-j-ray]

FRAMEWORK_SEARCH_PATHS = $(SDKROOT)/Developer/Library/Frameworks $(inherited) $(DEVELOPER_FRAMEWORKS_DIR)

[ikesyo]

How about if you add $(SRCROOT)/Carthage/Build/iOS to FRAMEWORK_SEARCH_PATHS? Although I don't know why the path doesn't exist in the setting (it would be added by adding a framework to "Link Binary With Libraries"), this should work I think.

[ikesyo]

(it would be added by adding a framework to "Link Binary With Libraries")

This is not the case for at least Xcode 7 beta 3, that might be an Xcode bug. 😲

[wm-j-ray]

Added $(SRCROOT)/Carthage/Build/iOS to FRAMEWORK_SEARCH_PATHS

Now she compiles but I get:

dyld: Library not loaded: @rpath/ReactiveCocoa.framework/ReactiveCocoa
  Referenced from: /Users/wmjray/Library/Developer/CoreSimulator/Devices/57501A15-C011-400D-9E9F-74BBC34EBAF2/data/Containers/Bundle/Application/E0CC903E-17CA-4BE9-88D2-6240D1C236FF/RWReactivePlayground.app/RWReactivePlayground

As an aside, over the night I completely de-installed xCode Beta-3, fried developer directories, etc., and re-downloaded and installed Version 7.0 beta 3 (7A152u. Also ran xCode : Open developer tool : simulator to make sure was talking to the proper simulator instance.

Still quite perplexed...

[ikesyo]

Is there the Embed Frameworks build phase? If there isn't, you should add a new "Copy Files Phase", then select "Framrworks" for Destination, add frameworks to the list, and check "Code Sign On Copy" checkboxes.

EDITED: You should also add $(inherited) @executable_path/Frameworks to "Runpath Search Paths" setting. Because the sample/starter project you are using is a bit old (dynamic framework is introduced in Xcode 6/iOS 8, but the project was created by Xcode 5), those settings required for using dynamic frameworks are not set up.

[ikesyo]

@wm-j-ray I've successfully compiled the starter project with the way in my latest comment. Could you please check that?

[wm-j-ray]

The starter project from here?

I'm trying to run Colin Eberhardt's tutorial from here: http://www.raywenderlich.com/62699/reactivecocoa-tutorial-pt1 but without the Cocoapods...

I made the change per your comment and I'm still getting the not loaded error. (I feel like a #@! Xcode noobie). Can you zip up that project and email it so I can finally see where I'm screwing up?

[milo-the-dev]

I was having the same issue. Seems that drag & dropping the frameworks from carthage was not also adding the $(SRCROOT)/Carthage/Build/iOS into the frameworks search path. Once I added that I was able to build and run

[wm-j-ray]

Confirmed. I want to thank all who helped out on this. I think we can close this one out.

[mdiep]

Thanks for helping out on this, @ikesyo! ✨

I am facing the same issue "dyld: Library not loaded: @rpath/AlgoliaSearch.framework/AlgoliaSearch" . I am using xcode7.3, frameworks search path is et to = $(SRCROOT)/Carthage/Build/iOS, added add $(inherited) @executable_path/Frameworks to "Runpath Search Paths" settings. I am also having Pod file in the project, is this causing the issue ? can someone help me please.

[nicolas-miari]

My 2 cents: Depending on where you have the Carthage directory relative to workspace/project etc. you might need to tweak the suggested Framework Search Path to (e.g.) $(SRCROOT)/../Carthage/Build/iOS.

[JohnTheBastard]

I just wanted to point out that there are two stupid mistakes I have made that resulted in this error, in case it helps anyone that comes across this thread.

• Once, in my build phase script, I accidentally cut and pasted /usr/local/bin/carthage copy-frameworks into the field for the shell (i.e. /bin/sh) instead of the correct field below it.

• The other time, I accidentally made my Cartfile and and ran carthage update from the directory above my project file, instead of in the same directory, so the copy-frameworks script did not have a correct relative path to actually copy the frameworks.

[seljabali]

My mistake: The Run Script which did /usr/local/bin/carthage copy-frameworks had additional logic in there. I created a new Run Script and moved that additional logic into it instead.
