How to run wxwidget application with DirectFB.

Hi,

I'm attempting to use the wxdfb library to execute a single frame.

I'm now using the 3.1.5 source of wxwidget, and I compiled it 
--with-directfb. After that, I obtained all the libraries in /usr/local/lib.

I installed the necessary DirectFB 1.7-7V package in my Ubuntu-20.01.1 
system prior to wwidget development.

Next, as per normal, I made a single frame that appeared in my programme. 
The code is below for your reference.

After the binary was built, I attempted to launch it by providing the 
inputs listed below. However, I was unable to see the frame and instead 
encountered other problems.

When I first executed the program, I thought the graphics window would 
appear shortly. However, after that, I fell into a stuck condition and was 
unable to use my keyboard or mouse.

If I check the console error, it appears to be created by the file below in 
the DFB source and is throwing incorrect parameters.
https://github.com/wxWidgets/wxWidgets/ ... rapdfb.cpp 
<https://github.com/wxWidgets/wxWidgets/blob/master/src/dfb/wrapdfb.cpp>

Resuming from the previous condition, I want to restart my machine.

Would you kindly offer some input on this? Is there something missing or am 
I running the binary with the right arguments?

*hello_world.cpp*
#include <wx/wx.h> 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(320, 240)); frame->Show(true); return true; } 
MyFrame::MyFrame(const wxString& title, const wxPoint& pos, const wxSize& 
size) : wxFrame(NULL, wxID_ANY, title, pos, size) { } 
wxIMPLEMENT_APP(MyApp);
