I'am trying to connect some data from protobuf to json.
This are the relevants parts of my code:
Message* m;
std::string json;
std::string binary_s;
...fill the message...
m->serializeToString(&binary_s);
MessageToJsonString(*m, &json);
The istruction below works fine and produced the expected output.
m->serializeToString(&binary_s);
But when I try to convert it into json, this error always appear:
Program received signal SIGSEGV, Segmentation fault.

It seems like it can't find the file "FLATBUFFER_DEFINITION.proto", but it is in the same directory of the executable.
