Apple Mach-O Linker Errors (20) - Undefined symbols for architecture armv7

Question

I received these errors after I added " -all_load " in the "Other Linker Flags" build setting once I added "libPusher-combined.a" and its header files. I followed the instructions exactly up to the part of typing in "-all_load" (under "Using a pre-compiled static library" in the "Adding to your iOS Project", but I ended up getting 20 Mach-O Linker errors. :/ Could anyone please help me with this?

Here are the errors:

If you need more information, just ask. I hope that I'm not giving too much trouble. Thanks in advance.

Check to make sure you included the following frameworks (via https://github.com/square/SocketRocket) :

Framework Dependencies

Your .app must be linked against the following frameworks/dylibs

libicucore.dylib CFNetwork.framework Security.framework Foundation.framework

ran into this adding a cocoapod for PonyDebugger. Solution worked. Thanks! – nh32rg May 22 '13 at 21:01

I just added the first one libicucore.dylib and fixed the problem (Foundation.framework was there already). – CodeBrew Jun 13 '14 at 18:44

Make sure that you also have -licucore in "Other Linker Flags", in the build settings tab, as in the attached screenshot:

Help me as well. After update to Xcode 7, this was removed for some reason. – Mikael Hellman Oct 30 '15 at 13:22

I copied the complete SocketRocket folder into my application for using web sockets in my application and linked libicucore.dylib, CFNetwork.framework, Security.framework, Foundation.framework binaries with my project. This removed all my errors and warnings.

For the latest sdk, you should add:

libicucore.tbd

since libicucore.dylib is not present anymore.

hope .tbd extension is not for "to be delete"?

Can you check out in your target->Build Phase. whether these files exist there or not ? and if you are running for simulator then first you need to make a build for simulator of that library whatever i guess you are using SRWebSocket library. Just open that project and just make a build for simulator and copy the files from build folder and then add to your project and do the same for the device if you are running your app on device.

Let me know, if you are still facing any problem. :) – Praveen-K Mar 29 '12 at 18:56
Well, it worked, and the errors are gone, but they are replaced by 13 warnings. – chrisjr Mar 29 '12 at 19:02
Hmmm, well those warning i guess you can solve. or just tell us those warnings, lets see if i can help you. – Praveen-K Mar 29 '12 at 19:05
Whoops. False alarm; the 20 errors are still there in addition to the 13 warnings. – chrisjr Mar 29 '12 at 19:05
The same errors that I was trying to get rid of in the first place are still there. But now, I also have 14 new warnings. – chrisjr Mar 29 '12 at 19:08
