How to enable boost in Code::Blocks 20.03?

Question

Code::Blocks

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;
}

Installed boost launched bootstrap.bat everything was going like. A bunch of lib files appeared in the stage\lib folder.
Then I followed this instruction carefully following all the steps.


Boost itself is in C:\boost
The global IDE variables are set to:
base C:\boost\boost
lib C :\boost\stage\lib

When trying to build, I get the following error:

-------------- Clean: Debug in api (compiler: GNU GCC Compiler)---------------

Cleaned "api - Debug"

--- ----------- Build: Debug in api (compiler: GNU GCC Compiler)---------------

g++.exe -Wall -fexceptions -g -IC: \boost\boost\include -c C:\api\api\main.cpp -o obj\Debug\main.o

#include
^~~~~~~~~~~~~~~~~~~~~
compilation terminated.
Process terminated with status 1 (0 minute(s), 0 second(s))
1 error(s), 0 warning(s) (0 minute(s), 0 second(s))

Actually, I understand that the error here is that C:\boost\boost\include does not exist, the filesystem.hpp file is located along the path C:\boost\boost\ where he got include from there, I personally do not understand at all.

I tried to set the path for the include in the global IDE variables,


but it did not help

In general, my level does not allow me to figure out this problem myself - tell me what's the matter, and how can this be fixed?

Answer 1

The include must specify the directory C:\boost
