The version is 1.1.7. platform and toolchain is vc6.0 and windows xp.
link error is:||Compiling...
practice.cxx
D:\code\FLTK\practise\practice.cxx(13) : error C2275: 'Fl_Timeout_Handler' :
illegal use of this type as an expression
c:\documents and
settings\user\desktop\fltk-1.1.7-source\fltk-1.1.7\fl\fl.h(48) : see
declaration of 'Fl_Timeout_Handler'
Error executing cl.exe.||
here i just use a simple example to get this straight:
#include<FL/Fl.H>
#include<FL/Fl_Window.H>
#include<FL/Fl_Button.H>
#include<Fl_Timer.H>
int main()
{
Fl_Window * win=new Fl_Window(400,400,500,500,"practice");
win->begin();
Fl_Button * but=new Fl_Button(100,100,100,30,"ServeOnOff");
Fl_Timer *timer=new Fl_Timer(FL_VALUE_TIMER,0,0,30,30,"TIMER");
Fl::add_timeout(1,Fl_Timeout_Handler);
win->end();
win->show();
return(Fl::run());
}
i link with the lib that ver1.1.7 gives us.
