[iOS] Error building Firebase, gRPC-C++ fatal error: 'chrono' file not found

[mtzfactory]

• Xcode version: 10
• Firebase SDK version: 5.8.0 / 5.9.0

Describe the problem

Compilation fails when try to build react-native app based in Firebase (using react-native-firebase), the error says it can't find 'chrono' file:

../../../ios/Pods/Headers/Public/gRPC-C++/grpcpp/impl/codegen/time.h:22:10: fatal error: 'chrono' file not found
#include <chrono>
         ^~~~~~~~

PD: I've already opened an issue at gRPC project...

Steps to reproduce:

Just create a react native app, and follow the instructions to install react-native-firebase, then run react-native run-ios.

Hi again,

I just updated to Firebase 5.7.0 and the same app builds and runs perfectly. It seems this version doesn't use gRPC-C++

Your problem here relates to the Xcode header map. The specific problem is that gRPC-C++ includes a file named time.h and there's a system header with the same name.

gRPC-C++ disables the header map for itself, but that's apparently not enough. Disable the setting "Use header maps" in your project to proceed.

[julo15]

I've been trying to get this working by disabling the header map and using 5.9.0 (i.e. not downgrading). Our build is succeeding locally always, but failing about 50% of the time on Buddybuild.

I'm wondering if anyone has successfully got this working via disabling the header map?

[tijunoi]

Nope, I've been trying for two days for all Firebase / RNFirebase version combos without success.
Somehow I got it to work yesterday removing some library links and adding them again, but I can't remember which ones. It worked for a few hours until I had to pod install again.

[codeflows]

Our builds are also failing on CircleCI somewhat randomly. Have tried tweaking the header map settings in our own project but to no avail. But, the errors I'm seeing are originating in RNFirebase so I guess this should be tracked there (see issue referenced above)

[tijunoi]

I also tried messing with headers with no success. I just solved the build error deintegrating pods and installing Firebase 5.9.0 again. It still wasn’t working until I switched to Legacy Build System in Xcode. Don’t like it that much but that’ll do for now.

Your problem here relates to the Xcode header map. The specific problem is that gRPC-C++ includes a file named time.h and there's a system header with the same name.

gRPC-C++ disables the header map for itself, but that's apparently not enough. Disable the setting "Use header maps" in your project to proceed.

This doesn't affect the build, still broken

[brenwell]

Any developments on this one?

[wilhuff]

Could someone share a project (ideally minimal) that's in this state? The steps to reproduce above are nontrivial. We don't formally support react native, don't test with it, and don't have a ton of experience with it. While I'd like to help I just don't have the kind of time it would take to reproduce this from the instructions above.
