I need to create a console application in Code::Blocks using some of wxWidgets classes (such as wxThread, wxHTTP, ...).
There are no "wxWidgets console application" wizard in Code::Blocks, so I choose just a "Console application", getting main.cpp created with the following code:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}
It compiles and runs Ok. When I replace it with a contents of examples/samples/console/console.cpp from wxWidgets's examples (skipped some text to be shorter):
// For compilers that support precompilation, includes "wx/wx.h".
#include "wx/wxprec.h"
#ifndef WX_PRECOMP
#include "wx/wx.h"
#endif
#include <wx/app.h>
#include <wx/cmdline.h>
// implementation
static const wxCmdLineEntryDesc cmdLineDesc[] =
{
...
};
int main(int argc, char **argv)
{
wxApp::CheckBuildOptions(WX_BUILD_OPTIONS_SIGNATURE, "program");
//!: **ERROR HERE:^**
wxInitializer initializer;
if ( !initializer )
{
fprintf(stderr, "Failed to initialize the wxWidgets library, aborting.");
return -1;
}
...
// do something useful here
return 0;
}
I got "undefined reference to wxAppConsoleBase::CheckBuildOptions(char const*, char const*)" error (gcc) at specified line.
What am I doing wrong?
How to fix this?
I can compile my GUI projects with wxWidgets (version 3.0) with no problem, so it looks like I need to specify some defines, includes or any other magic to make it work. I tried to understand example's makefile, but with no luck.
