Hello everyone,

I use Geany for many years for Pearl and MQL4 language but I would like to learn standard c++ with Geany and I have some problems to compile :

My example program :
//#include <wx/wx.h>
#include "/usr/include/wx-3.2/wx/wx.h"  // this file exists !

class MyApp : public wxApp
{
public:
    virtual bool OnInit();
};

class MyFrame : public wxFrame
{
public:
    MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size);
};

bool MyApp::OnInit()
{
    MyFrame *frame = new MyFrame("Hello World", wxPoint(50, 50), wxSize(450, 340));
    frame->Show(true);
    return true;
}

MyFrame::MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size)
        : wxFrame(NULL, wxID_ANY, title, pos, size)
{
    wxMenu *menuFile = new wxMenu;
    menuFile->Append(wxID_EXIT);
    wxMenuBar *menuBar = new wxMenuBar;
    menuBar->Append(menuFile, "&File");
    SetMenuBar(menuBar);
    CreateStatusBar();
    SetStatusText("Welcome to wxWidgets!");
}

wxIMPLEMENT_APP(MyApp);


WHEN I BUILD :

g++ -Wall -o "wxhello" "wxhello.cpp" (dans le dossier : /home/jpc/projets/Learning_Cpp)
In file included from wxhello.cpp:2:
/usr/include/wx-3.2/wx/wx.h:14:10: fatal error: wx/defs.h: Aucun fichier ou dossier de ce type
   14 | #include "wx/defs.h"
      |          ^~~~~~~~~~~
compilation terminated.
Compilation échouée.

What, where and how to configure Geany Please ?
