How to enable boost in Code::Blocks 20.03?
I wanted to study boost and decided to build a demo example
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;
using namespace boost::filesystem;
const char * say_what(bool b) { return b ? "true" : "false"; }
int main(int argc, char* argv[])
{
if (argc < 2)
{
cout << "Usage: path_info path-element [path-element...]\n"
"Composes a path via operator/= from one or more path-element arguments\n"
"Example: path_info foo/bar baz\n"
# ifdef BOOST_POSIX_API
" would report info about the composed path foo/bar/baz\n";
# else // BOOST_WINDOWS_API
" would report info about the composed path foo/bar\\baz\n";
# endif
return 1;
}
path p;
for (; argc > 1; --argc, ++argv)
p /= argv[1]; // compose path p from the command line arguments
cout << "\ncomposed path:\n";
cout << " operator<<()---------: " << p << "\n";
cout << " make_preferred()-----: " << p.make_preferred() << "\n";
cout << "\nelements:\n";
for (auto element : p)
cout << " " << element << '\n';
cout << "\nobservers, native format:" << endl;
# ifdef BOOST_POSIX_API
cout << " native()-------------: " << p.native() << endl;
cout << " c_str()--------------: " << p.c_str() << endl;
# else // BOOST_WINDOWS_API
wcout << L" native()-------------: " << p.native() << endl;
wcout << L" c_str()--------------: " << p.c_str() << endl;
# endif
cout << " string()-------------: " << p.string() << endl;
wcout << L" wstring()------------: " << p.wstring() << endl;
cout << "\nobservers, generic format:\n";
cout << " generic_string()-----: " << p.generic_string() << endl;
wcout << L" generic_wstring()----: " << p.generic_wstring() << endl;
cout << "\ndecomposition:\n";
cout << " root_name()----------: " << p.root_name() << '\n';
cout << " root_directory()-----: " << p.root_directory() << '\n';
cout << " root_path()----------: " << p.root_path() << '\n';
cout << " relative_path()------: " << p.relative_path() << '\n';
cout << " parent_path()--------: " << p.parent_path() << '\n';
cout << " filename()-----------: " << p.filename() << '\n';
cout << " stem()---------------: " << p.stem() << '\n';
cout << " extension()----------: " << p.extension() << '\n';
cout << "\nquery:\n";
cout << " empty()--------------: " << say_what(p.empty()) << '\n';
cout << " is_absolute()--------: " << say_what(p.is_absolute()) << '\n';
cout << " has_root_name()------: " << say_what(p.has_root_name()) << '\n';
cout << " has_root_directory()-: " << say_what(p.has_root_directory()) << '\n';
cout << " has_root_path()------: " << say_what(p.has_root_path()) << '\n';
cout << " has_relative_path()--: " << say_what(p.has_relative_path()) << '\n';
cout << " has_parent_path()----: " << say_what(p.has_parent_path()) << '\n';
cout << " has_filename()-------: " << say_what(p.has_filename()) << '\n';
cout << " has_stem()-----------: " << say_what(p.has_stem()) << '\n';
cout << " has_extension()------: " << say_what(p.has_extension()) << '\n';
return 0;
}
