Hello.
I want to use Derelict-SFML2 to create a simple window.
But when I compile (linked with dub and derelict-util), I have
the following error:
src/app.d(30,20): Error: variable myproject.main.window no
definition of struct sfRenderWindow
../../../.dub/packages/derelict-sfml2-3.0.1/source/derelict/sfml2/graphics.d(56,1):

Is it a bug in Derelict-SFML2 or want did I do false ?
Hoping that you understood me with my bad English :)
sfRenderWindow is an opaque struct, so its size is unknown.
This means you can only use pointers to them, and any
operations on them will have to be done using SFML. So in your
code, change sfRenderWindow to sfRenderWindow*.
Did you by any chance look at a C++ tutorial for SFML? Derelict
binds to the C API so it looks a bit different. To create a
window sfRenderWindow_create can be used, so lines 12 + 13 can
be replaced by
auto window = sfRenderWindow_create(sfVideoMode(200, 200),
"SFML works !");
Another example: the function to check if a window is open is
sfRenderWindow_isOpen, taking a pointer to an opaque
sfRenderWindow struct as first parameter. Due to D's so called
UFCS you can call this function in two ways:
sfRenderWindow_isOpen(window); // Just like in C
window.sfRenderWindow_isOpen(); // Use member-like syntax
Thank you.
I've this code now:
----------
sfRenderWindow* win = sfRenderWindow_create(sfVideoMode(200,
200), "SFML works !", 0, null);
sfEvent* event;
while (win.sfRenderWindow_isOpen())
{
while (win.sfRenderWindow_pollEvent(event))
{
if (event.type == sfEvtClosed)
win.sfRenderWindow_close();
}
}
---------
But when compiling I got this error:
derelict.util.exception.SymbolLoadException@../../../.dub/packages/derelict-util-2.0.4/source/derelict/util/exception.d(35):
Failed to load symbol sfJoystick_getIdentification from shared library

Any ideas ?
