How to Test C++ Boost Installation
Once C++ Boost is installed on a machine, the fastest way to test the installation is to use some of the libraries from it in test C++ programs and try to build them. The following two programs can be used for this purpose:
first.cpp
C++:
#include<iostream>
#include<boost/any.hpp>
int main()
{
boost::any a(5);
a = 7.67;
std::cout<<boost::any_cast<double>(a)<<std::endl;
}
Build this program using:
sh# g++ -o first first.cpp
The second example needs to be linked to a library file.
second.cpp
C++:
#include<iostream>
#include<boost/filesystem/operations.hpp>
namespace bfs=boost::filesystem;
int main()
{
bfs::path p("second.cpp");
if(bfs::exists(p))
std::cout<<p.leaf()<<std::endl;
}
sh# g++ -o second second.cpp -lboost_filesystem
If the above two programs build and run with out any problems, then boost is installed and working properly on your system.
