why can not use "sfSprite"

[windhl]

when I want to create a sfSprite instance like this:

Code: [Select]


.....
   //1.create a Image in the memory
    sfImage Image;
    if(!Image.LoadFromFile("windhl.jpg"))
      return EXIT_FAILURE;
     
    //2.create a spirte
    sfSprite Sprite;
    Sprite.SetImage(Image);
......


the compile Error is

  variable 'vtable for sfSprite' can't be auto-imported. Please read the documentation for ld's --enable-auto-import for details.

so  I want to know WHY?  and  what's "ld's" ?

Thank u  for your help ~~~

[Laurent]

It happens with MinGW and SFML dynamic libraries, I still don't know why. The only solution at the moment is to use static libraries instead.

ld is the name of the linker

[windhl]

thank u ~~~ I'll try again~~~ :roll:

[windhl]

I have tried some times

however     it does not work with the static **.a or **-d.a

i use static libs in this order:

D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-system.a
D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-system-d.a

D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-graphics-d.a

but there are too many errors like these:

  [Linker error] undefined reference to `sfClock::GetElapsedTime() const'
  [Linker error] undefined reference to `sfClock::Reset()'
  ...
  more undefined references to `sfClock::Reset()' follow
  [Linker error] undefined reference to `sfClock::sfClock()'
  ...
  [Linker error] undefined reference to `glBegin@4'
  ...
  [Linker error] undefined reference to `glTexImage2D@36'
  ...
  ld returned 1 exit status

and the compile info is:

[Laurent]

i use static libs in this order:

D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-system.a
D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-system-d.a
D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-window.a

D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-graphics.a
D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-graphics-d.a

Use the "-d" libraries in debug mode, and the others in release.
And also use the reverse order :

D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-graphics.a
D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-window.a
D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-system.a

And for debug :

D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-graphics-d.a
D:/windhl/SFML-1.0-sdk/SFML-1.0/lib/mingw/static/libsfml-window-d.a
