Question

I\'m trying to run program, using sample code of boost::filesystem on Ubuntu 12.10, but it doesn\'t want to build.

#include 

        

Answer 1

You need to add libboost_filesystem library when linking. Or libboost_filesystem-mt if your application is multi-threaded. Like this:

g++ -o file -lboost_filesystem-mt source_file.cpp
