GOOGLE_LOG - where is the log to inspect protobuf errors etc.

[hesingh]

In protobuf/src/google/protobuf/text_format..cc on line 299, I see a GOOGLE_LOG used.

I am using protobuf with c++ on Ubuntu 18.04.

In several gdb debugging tries, once I could see this message in my debugging. By, default, where are these messages going so that I could see all GOOGLE_LOG messages?

I am using a P4Runtime application that uses gRPC and protobuf.

The default log handler just sends messages to stderr, but you might need to check that GOOGLE_PROTOBUF_MIN_LOG_LEVEL was set to an appropriate level (should be set to LOGLEVEL_INFO if you want to see all log messages.)

Thanks much!
