Problem with compiling a mingw32 executable on linux system with boost.asio

Question

When I am compiling a Boost.asio program with the code:

g++ -o main main.cpp -lboost_system -lboost_thread -pthread

It just works fine, but if I compile it for windows on linux system as an executable with the code:

x86_64-w64-mingw32-g++ -I /usr/include/boost -o main.exe main.cpp -lboost_system -lboost_thread -pthread 

or

x86_64-w64-mingw32-g++ -o main.exe main.cpp -lboost_system -lboost_thread -pthread 

There is a compile Error

fatal error: boost/asio/io_service.hpp: No such file or directory
 #include <boost/asio/io_service.hpp>

I mean I tried so many things to solve it and it makes me so angry do you know why?

Answer 1

When it comes to Windows, you should add the winsockets libraries as a compilation parameter.

g++ -o main.exe main.cpp -lboost_system -lboost_thread -pthread -lws2_32 -lwsock32

Normally only "ws2_32" is enough.

Note: Winsock2 (ws2_32) is an extension to Winsock1 (wsock32). A program that currently works against wsock32 should still work fine when relinked against ws2_32.
