Compile error

[alexanderkoller]

I get a protobuf-related error message when trying to compile infrastructure. This is with Java 15 on the Mac (M1).

Looks like a known problem, with an intermediate fix applied in May: protocolbuffers/protobuf#8557 Updating to protobuf 3.18 should fix the problem, but I can’t test that on my end, as I don’t have an M1 processor at hand. Alexander, can you try that?

[alexanderkoller]

I can try that, but what do I have to do to make Gradle look for the new Protobuf in the right place?

in networking/build.gradle, change

def protocVersion = '3.11.0'

to

def protocVersion = '3.18.0'

However, that does not compile on my machine and I don’t understand why. You can try 3.17.0 and see whether that works and bump the grpc version to 1.41.0 while you are at it (same place).

That changes the way in which the compile fails, see below. Maybe grpc needs to be updated to work with M1 too?

Maybe, but 1.41 is the newest version, from three days ago. Seems like it just needs more time until M1-based systems are mainstream enough to be generally supported.
