Hi All
I am getting some errors where at a certain amount of data the
protobuf.has_scalar_value() will show false.
But I am sure that there is indeed more data because I can see it in the
response I received from the server.
However the server is a Java implementation of Apache Calcite running
Protobuf V3.6.1.
At first my C++ program was running Protobuf V3.13.0 and I kept on getting
errors when the data exceeds a certain amount of data. I AM NOT however
sure that, that is indeed the case but the current error is very obscure at
this stage.
So then to try and remedy the situation I pulled TAG Protobuf V3.6.1 and I
compiled it.
Ran protoc on them and I got the following error WHICH I didn't receive in
3.13.0 AND ALSO not on the Java server side running same version. ALSO This
is done on a newly installed Ubuntu server 20 OS.
protoc -I=. --cpp_out=. ./common.proto
protoc -I=. --cpp_out=. ./request.proto
protoc -I=. --cpp_out=. ./response.proto
g++ -g -fPIC -c common.pb.cc -L/usr/local/lib `pkg-config --cflags --libs
protobuf` -Wl,--no-as-needed -lgrpc++_reflection -Wl,--as-needed -ldl -o
common.o -std=c++14

222 | NULL = 24,

common.pb.h:222:3: error: expected ‘}’ before ‘__null’
So my question is. How is it possible that Protobufs work on the Java
server but not on my C++ implementation with the same Proto files and same
version compiled for this OS?
Is it a bug in the V3.6.1 ?
