Description

I cannot build idb_companion in Xcode 15.0 on the current master (2022-09-19).

Reproduction

Actually, when I follow the documentation even this step fails as there is no Podfile ...

➜  idb git:(main) pod install
[!] No `Podfile' found in the project directory.
➜  idb git:(main)

@mforys you should install protoc first.

Similar issue here,

./idb_build.sh idb_companion build /Users/JJ/Downloads

/bin/sh: line 6: protoc: command not found
Command RuleScriptExecution failed with a nonzero exit code

note: Run script build phase 'Build Shimulators' will be run during every build because the option to run the script phase "Based on dependency analysis" is unchecked. (in target 'FBControlCore' from project 'FBSimulatorControl')
/Users/jj/Github/idb/idb_companion.xcodeproj: warning: DEFINES_MODULE was set, but no umbrella header could be found to generate the module map (in target 'IDBGRPCSwift' from project 'idb_companion')
** BUILD FAILED **


The following build commands failed:
	RuleScriptExecution /Users/jj/Github/idb/build/Build/Intermediates.noindex/idb_companion.build/Release/IDBGRPCSwift.build/DerivedSources/idb.pb.swift /Users/jj/Github/idb/build/Build/Intermediates.noindex/idb_companion.build/Release/IDBGRPCSwift.build/DerivedSources/idb.grpc.swift /Users/jj/Github/idb/proto/idb.proto normal undefined_arch (in target 'IDBGRPCSwift' from project 'idb_companion')

Fixed by re-installing protobuf and force symlinking it.

brew install protobuf
brew link --overwrite protobuf
which protoc
/opt/homebrew/bin/protoc

Re-running the idb_build.sh works now.

Compiling using idb_companion.xcworkspace works now too!

This might be slightly off-topic, but I didn't find any information on this elsewhere:
If we build idb-companion, how can we "use" it?
Do I need to tell the python client somehow to use the built version rather than the official version?
