betatim / serial.cpp
Created July 17, 2013 07:44
On my mac it compiles with: $ g++ -g serial.cpp -o serial -lboost_serialization-mt running it create dead_pixels.archive $ ./serial somewhere I have the magic line to add to the requirements file to get it to link to boost_serialisation ...
#include <fstream>
#include <map>
#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>
#include <boost/serialization/map.hpp>
int main() {
std::ofstream ofs("dead_pixels.archive", std::ios::binary);
