Protobuf error compiling on macOS

[Marquis Wong]

Hello,

I'm trying to build Gerrit on macOS, and I keep on getting errors related to compiling protobuf.

In file included from external/com_google_protobuf/src/google/protobuf/stubs/statusor.cc:31:

external/com_google_protobuf/src/google/protobuf/stubs/statusor.h:193:29: error: no member named 'UNKNOWN' in 'google::protobuf::util::status_internal::Status'

    : status_(util::Status::UNKNOWN) {

              ~~~~~~~~~~~~~~^

    status_ = Status(error::INTERNAL, "Status::OK is not a valid argument.");

                     ^

external/com_google_protobuf/src/google/protobuf/stubs/statusor.h:208:22: error: use of undeclared identifier 'error'

    status_ = Status(error::INTERNAL, "nullptr is not a valid argument.");

external/com_google_protobuf/src/google/protobuf/stubs/statusor.h:210:23: error: no member named 'OK' in 'google::protobuf::util::status_internal::Status'

    status_ = Status::OK;

I suspect my problem is the gcc version.

I've been using what I think is the default version that gets installed with Xcode

✗ gcc --version

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

Apple clang version 13.0.0 (clang-1300.0.29.3)

Target: x86_64-apple-darwin20.6.0

Thread model: posix

InstalledDir: /Library/Developer/CommandLineTools/usr/bin

I'm running macOS Big Sur 11.6, and Java 11:

✗ java -version

openjdk version "11.0.12" 2021-07-20

OpenJDK Runtime Environment Homebrew (build 11.0.12+0)

OpenJDK 64-Bit Server VM Homebrew (build 11.0.12+0, mixed mode)

The documentation doesn't say what GCC versions are required. I've successfully build on Linux with gcc 4.8.5, but it's difficult to get that version installed on Big Sur.

I am on MacOS 11.6 and have XCode 13.0 installed.

With that the gcc version is:

$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

Apple clang version 13.0.0 (clang-1300.0.29.3)
Target: x86_64-apple-darwin20.6.0
Thread model: posix

InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

 

and I can build gerrit with that

-Matthias

I did get this issue resolved, if you're having the exact same error.

It wasn't an issue with GCC, but rather other protobuf versions installed. Gerrit depends on protobuf 3.14, and I had a different version already installed. I uninstalled it (and the things depending on it, which included MySQL, which was somewhat inconvenient), and Gerrit built successfully.

I eventually decided to build inside a Docker image instead to avoid random dependencies breaking the build.
