Crashlytics error: Undefined symbols for architecture arm64

Question

After I updated Fabric Crashlytics in my app I cant anymore run it on my iOS device. On simulator it works fine. Error is:

Undefined symbols for architecture arm64: "_gzopen", referenced from: -[CLSPackageReportOperation compressFile:] in Crashlytics(CLSPackageReportOperation.o) "_gzwrite", referenced from: ___42-[CLSPackageReportOperation compressFile:]_block_invoke in Crashlytics(CLSPackageReportOperation.o) "_gzclose", referenced from: -[CLSPackageReportOperation compressFile:] in Crashlytics(CLSPackageReportOperation.o) ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've already answered that question on this post: [https://stackoverflow.com/a/45569861/8434514](https://stackoverflow.com/a/45569861/8434514) — Rodrigo Soldi Lopes, Aug 08 '17 at 15:09

Crashlytics and Fabric require you to link your target against the following:

Security.framework
SystemConfiguration.framework
libc++
libz

Just select your target -> Build Phases -> Link Binary with Libraries -> add the ones missing.

I hope it helped.

This works. Make sure you also add this to any test targets! That was my problem. – Tori Huang Nov 09 '17 at 18:22

I solved this issue by just adding $(inherited) to other linker flags in Build Settings.

I run into a similar issue, when I was updating an app that was created before Xcode 5.

Since Xcode 5 new projects build with modules enabled by default. In my old app "Enable Modules" was set to "No". So this was the solution.

For me, the solution was Build Phases - Link Binary With Libraries add libc++ and works, in my legacy project.

Solved. I removed Crashlytics.framework and reinstall it.

My solution for this problem was:

Change "Build Active Architecture Only" to "Yes" also for "Release".

The setting can be found selecting your project > "Build Settings" > "Targets" (your target) > "Architectures"

do it in your project targets and also do it in your projectTest targets

Extending Ricardo's answer here. Select the “Build Phases” tab, click the “+” next to “Link Binary With Libraries” and add -

Security.framework
SystemConfiguration.framework
StoreKit.framework
libsqlite3.tbd
libz.tbd
libc++.tbd

As per Google, developers should use Crashlytics via Firebase. This worked for me as of Firebase v5.16.0 and Fabric v1.9.0 (Xcode 10.1).

I solved the issue by adding $(inherited) $(OTHER_LDFLAGS) -ObjC -l"sqlite3" -l"z" -l"c++" -framework "Crashlytics" -framework "Fabric" -framework "Security" -framework "SystemConfiguration" -framework "UIKit" to other linker flags in Build Settings.

In Project(not target) Info tab set the configuration file to none and run pod install again

On M1 Mac

In Excluded Architectures Add "Any iOS Simulator SDK" - "arm64" in Target, Test, and all libraries you added.

I solved it by removing "library which causes the error" from other linker flags.
