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
libcsfml-window.so
Any ideas ?
You have old version of libcsfml that lacks of symbol
sfJoystick_getIdentification. Try another version, may be build it from
sources to have the newest one.
