I'm trying to both serialize and deserialize the data in a graph format.
The definition of my graph is the following one.
#include
#include
#include
#include
#include
#include
#include
class VFull {
public:
VFull();
unsigned int id, hash, year;
std::string ip, organization;
VFull(unsigned int id, unsigned int hash, unsigned int year,
std::string ip, std::string organization);
template<class Archive> void serialize(Archive & ar, const unsigned
int version);
};
class EFull {
public:
EFull();
template<class Archive> void serialize(Archive & ar, const unsigned
int version);
};
class GFull {
public:
template<class Archive> void serialize(Archive & ar, const unsigned
int version);
};
//Defining the graph data structure. Using the vecS specification
typedef boost::adjacency_list graph_t;
typedef boost::graph_traits::vertex_descriptor
result_vertex_descriptor;
typedef boost::graph_traits::edge_descriptor
result_edge_descriptor;
It seems to me that I have no problems in the serialization process,
while I have some issues in the deserialization part. In fact, I have no
linking errors until this piece of code is added to my source:
#include <iomanip>
#include <iostream>
#include <fstream>
{
std::ifstream file(path,std::ios_base::binary);
boost::archive::binary_iarchive store{file};
store >> graph; // Deserialization part that triggers the error
}
I tried to read some questions here and to read the Boost manual, but
they didn't solve my problem. In particular, I have this error:
Undefined symbols for architecture x86_64:
"void

unsigned int)", referenced from:

boostOthers.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see

By the way, I'm serializing and deserializing strings and unsigned ints,
"native data types" that seems to be supported by boost:
//VERTICES
VFull::VFull() { }
VFull::VFull(unsigned int i, unsigned int h, unsigned int y, std::string
p, std::string o) :
id{i}, hash{h}, year{y}, ip{p}, organization{o} {
}
template<class Archive> void VFull::serialize(Archive &ar, const
unsigned int version) {
ar & 'i'; ar & id;
ar & 'h'; ar & hash;
ar & '1'; ar & ip;
ar & '2'; ar & organization;
ar & '3'; ar & year;
ar & '/';
}
///////
//EDGES
EFull::EFull() { }
template<class Archive> void EFull::serialize(Archive &ar, const
unsigned int version) {
char waste = 'e';
ar & waste; }
///////
//GRAPH SIGNATURE
template<class Archive> void GFull::serialize(Archive &ar, const
unsigned int version) {
std::string waste = "GBLS";
ar & waste;
}
///////
Yes, I am linking my source code to both BGL and Boost's serialization.
This is acheived through this part of CMake script:
find_package( Boost REQUIRED COMPONENTS graph serialization )
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED OFF)
INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIRS} ..some other stuff..)
TARGET_LINK_LIBRARIES(mycode ${Boost_LIBRARIES})
