I would like to print a debug message for a type (let's say the type is
'MessageType'), that is not known at compile time. It works fine when
compiling with gcc, with Visual Studio however I receive the following
error message:
[libprotobuf WARNING
...\protobuf-cpp-3.21.9__\protobuf-3.21.9\src\google\protobuf\text_format.cc:2157]
Can't print proto content: proto type type.googleapis.com/MessageType not
found
This is the code I run:
google::protobuf::Any msg;
msg.ParseFromArray(msg_ptr, msg_size);
std::cout << msg.DebugString() << std::endl;
// parseFromArray<MessageType>( msg_ptr, msg_size ); <-- This is not needed
when compiling with gcc
with
template<typename M>
static M parseFromArray( const void* msg, size_t size )
{
M result;
google::protobuf::Any any;
any.ParseFromArray( msg, static_cast<int>( size ) );
return parseFromAny<M>( any );
}
So, with Visual Studio I have to parse the any message to the actual
received type at least once and somewhere (note, that 'parseFromArray' is
called AFTER DebugString()).
Any ideas/suggestions what to try here?
Thanks in advance!
Tested with
- Protobuf 3.11.2 and 3.21.9
- Visual Studio 2022
- Ubuntu 22 with gcc
