CocoaPods Protobuf umbrella header issue
What version of protobuf and what language are you using? Version: 3.12.0, 4.0.0-rc1 Language: Objective-C
What operating system (Linux, Windows, ...) and version? macOS 10.15.6
What runtime / compiler are you using (e.g., python version or gcc version) Xcode 11.6.0
What did you do?
Steps to reproduce the behavior:
Import the generated umbrella header: #import <Protobuf-umbrella.h>
What did you expect to see Everything build normally - or at least without straight-up errors, just as it would if the project did not use it.
What did you see instead? This error and three other like errors:
❌ /Users/distiller/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphonesimulator/Protobuf/Protobuf.framework/Headers/GPBAny.pbobjc.h:48:11: duplicate interface definition for class 'GPBAnyRoot'
GPB_FINAL @interface GPBAnyRoot : GPBRootObject
I suspect the error is due to the umbrella header importing both GPBAny and Any, et cetera.
Anything else we should know about your project / environment This error did not occur before the upgrade to 3.12.0.
Is there a longer version of the error message? Does it say where it things both definitions come from?
@paulb777 any ideas?
Is the old file imports the new, I would have hoped there was only a single definition to be seen.
Does using module syntax make a difference? @import Protobuf;?
A reproducible example would be helpful.
@thomasvl No problem. Here's an example: https://github.com/UInt2048/tsurukame/commit/dd7146e9800e554c86513c300d444c9b7d63bec9
Here's a screenshot:
@paulb777 Using module syntax would likely work - the issue is only with the umbrella header. However, the compiler complains about C++ modules being disabled, so I can't directly answer.
It works normally without it (I have converted the file in question to Swift already in the main branch)
The screenshot doesn't actually provide the details that are in the Xcode log. All the screen shot has is "Previous definition is here", and you'd have to click on it to see where. The text in the build log would have everything.
@thomasvl How could I share the full build log? Sometimes I would love to actually see it.
I did provide an example commit (admittedly a much larger example than the theoretical smallest possible)

Expand open the log and you can copy the text. Here's an example of getting some of it: https://stackoverflow.com/questions/30060898/xcode-how-to-see-build-command-and-log

I don't think @paulb777 or I have had the chance to look. Yes, it is a commit, but since we aren't familiar with the project theres a bit of a curve since it appears to be Go code, so for someone to look, they have to figure out the build process, what are the dependencies, etc. Since this is a cocoapods issue, it wasn't immediately visible how that comes into play.
Based on what you shared, here's the relevant portion of the build log, as experienced again in a different commit on macOS 10.13.6 on Protobuf 3.13.0:

Sorry for the long delay. Are you still seeing this error in newer versions of protobuf?
