I am running ubuntu 16.04 with gcc.
My q.ccp
file is
#include <google/protobuf/generated_message_util.h>
#include <google/protobuf/repeated_field.h>
#include <google/protobuf/extension_set.h>
#include <google/protobuf/generated_message_reflection.h>
#include <google/protobuf/generated_message_util.h>
#include <google/protobuf/stubs/common.h>
#include <google/protobuf/descriptor.h>
int main(int argc, char **argv)
{
google::protobuf::Message* msg;
const google::protobuf::Descriptor* message_desc = msg->GetDescriptor();
const google::protobuf::FieldDescriptor * fd_name = message_desc->FindFieldByName("name");
return 0;
}
command used for compilation:
g++ -D_GLIBCXX_USE_CXX11_ABI=0 q.cpp -L/usr/lib/x86_64-linux-gnu /usr/local/lib/libprotobuf.a -lpthread
protoc --version
returns: 2.2.0
gcc --version

compile error:
/tmp/cciGJPqq.o: In function `main':
q.cpp:(.text+0x5f): undefined reference to `google::protobuf::Descriptor::FindFieldByName(std::string const&) const'
collect2: error: ld returned 1 exit status
But when I leave the -D_GLIBCXX_USE_CXX11_ABI=0
option, I get no compile error. But the problem is that I running the executable on different system which require compilation with this option for the program to run.
If your compilation succeeds only with D_GLIBCXX_USE_CXX11_ABI=0, then you may be using a shared library (libprotobuf) that is precompiled using the same or using an older ABI, like gcc 4.8.
I would check the g++ version. It may be > 5, which would have the newer ABI.
