Hi,
Does anyone know if Protobuf's C++ output is ever going to support
enum classes? I'd like to be able to define the elements of my enum in
just one place (i.e. in the message definition file) and then use that
definition throughout my program, but I'd like it to be defined as an
enum class
Did you include the output of pkg-config --libs protobuf in your
linker command line?

Assuming you have a MyMessage, use the has_messagecommand() and
has_messageclose() functions to figure out whether each optional
field is present or absent.

Did you remember to delimit your protobuf messages when sending them
over your sockets? Your use of send() suggests you're using a stream
socket and not a datagram socket (though that's no guarantee). If you
tell Protobuf to decode starting from the wrong place, or don't give

Protobuf messages are not aware of their own sizes, and you haven't
told the input stream how many bytes of message it should consume. Try
this:
coded_input-ReadLittleEndian32(objtype);
coded_input-ReadLittleEndian32(objlen);
CodedInputStream::Limit lim = coded_input-PushLimit(objlen);

If you're worried, just spec your format such that when you write a

Protobuf messages do not have inherent delimiters; in fact, the
concatenation of two messages can sometimes be a perfectly valid single
message. Add delimiters in your protocol (if you are only sending a single
message then just shutdown() the socket afterwards and have the recipient

You need to know how long the data will be, since Protobuf doesn’t tell
you that. Your protocol somehow decides that. Either you receive up to
EOF and that’s a message, or else the length of the message appears in
front of the message itself. I
Hi,
The -I option specifies where to look for files you refer to with
“import”. It is not used for the file you are trying to compile. You
want this:

If “AddressBook.proto” imports other proto files, you may then need to
add a -I

After unpacking your RAR file to get protobuff.log, I examined that

messages, and each message has a big-endian uint32 stuck in front of it
which is the length of the following message. For example, the first
four bytes are 0x00,

Use the mutable_header() function instead. This creates the contained
object if it does not already exist, and returns a pointer instead of a
reference.
