Linker error when compiling boost.asio example

Question

I\'m trying to learn a little bit C++ and Boost.Asio. I\'m trying to compile the following code example:

#include 
#include 

        

Answer 1

You need to tell g++ where the header files are, where the libraries are and which library you are using, e.g. on my system:

g++  -I /opt/local/include -L /opt/local/lib -lboost_system-mt -lboost_thread-mt a.cpp

where -I tells g++ where the header files are and -L tells g++ where the actual libraries are and -lboost_thread-mt is the library I want to link against in the -L folder.
