We saw that Boost C++ libraries were developed to complement the standard C++ library. We have also been able to set up our MinGW compiler in order to compile the code that contains Boost libraries and build the binaries of libraries that have to be compiled separately. In the next chapter, which talks about the Boost.Asio library (the library we are going to use to develop network applications), we will delve into Boost libraries specifically. Please remember that although we can use the Boost.Asio library as a header-only library, it would be better to build all Boost libraries by using the Boost.Build library. It will be easy for us to use all libraries without worrying about compiling failure.
