incompatible type for argument 4 of ‘sfWindow_Create’

[Hohoo]

I'm writing my Vala bindings, but something seems to be wrong. On line 27 (if (sfVideoMode_IsValid (&vm))) I get this error:

test.c:27: error: incompatible type for argument 1 of ‘sfVideoMode_IsValid’

(For those who don't know: Vala is translated into C first and then compiled.)

Here is the code:

Code: [Select]

/* test.c generated by valac, the Vala compiler
 * generated from test.vala, do not modify */


#include <glib.h>
#include <glib-object.h>
#include <SFML/Window.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>




gint _vala_main (char** args, int args_length1);



gint _vala_main (char** args, int args_length1) {
gint result = 0;
sfContextSettings _tmp0_ = {0};
sfContextSettings cs;
sfVideoMode _tmp1_ = {0};
sfVideoMode vm;
cs = (_tmp0_.DepthBits = (guint) 800, _tmp0_.StencilBits = (guint) 600, _tmp0_.AntialiasingLevel = (guint) 32, _tmp0_.MajorVersion = (guint) 2, _tmp0_.MinorVersion = (guint) 0, _tmp0_);
vm = (_tmp1_.Width = (guint) 320, _tmp1_.Height = (guint) 240, _tmp1_.BitsPerPixel = (guint) 32, _tmp1_);
if (sfVideoMode_IsValid (&vm)) {
fprintf (stdout, "%d\n", (gint) cs.MajorVersion);
}
result = (gint) sfNone;
return result;
}


int main (int argc, char ** argv) {
g_type_init ();
return _vala_main (argv, argc);
}

The compiler is right, sfVideoMode_IsValid doesn't want a pointer.

Code: [Select]

sfVideoMode_IsValid (vm)

[Hohoo]

The compiler is right, sfVideoMode_IsValid doesn't want a pointer.

Code: [Select]

sfVideoMode_IsValid (vm)

Ok, but when I do that, I get this error instead:

undefined reference to `sfVideoMode_IsValid'

Even though I linked to sfml-window and sfml-system

[Laurent]

You must link to csfml-window and csfml-system.

[Hohoo]

Eh

./test: error while loading shared libraries: libsfml-window.so.1.5: cannot open shared object file: No such file or directory

I'm using SFML2 but it seems to be looking for an ancient version...

EDIT: Fixed; turned out there was something wrong with my CSFML libs.

[Hohoo]

Sorry for the double post, but I have no idea what's going on with this code:

Code: [Select]

/* test.c generated by valac, the Vala compiler
 * generated from test.vala, do not modify */


#include <glib.h>
#include <glib-object.h>
#include <SFML/Window.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define _sfWindow_Destroy0(var) ((var == NULL) ? NULL : (var = (sfWindow_Destroy (var), NULL)))



gint _vala_main (char** args, int args_length1);



static sfContextSettings sfml_window_create_context_settings (guint depth_bits, guint stencil_bits, guint antialiasing_level, guint major_version, guint minor_version) {
sfContextSettings result;
sfContextSettings _tmp0_;
result = (_tmp0_.DepthBits = depth_bits, _tmp0_.StencilBits = stencil_bits, _tmp0_.AntialiasingLevel = antialiasing_level, _tmp0_.MajorVersion = major_version, _tmp0_.MinorVersion = minor_version, _tmp0_);
return result;
}


gint _vala_main (char** args, int args_length1) {
gint result = 0;
sfContextSettings cs;
sfVideoMode _tmp0_;
sfVideoMode vm;
sfWindow* w;
cs = sfml_window_create_context_settings ((guint) 800, (guint) 600, (guint) 32, 2, 0);
vm = (_tmp0_.Width = (guint) 320, _tmp0_.Height = (guint) 240, _tmp0_.BitsPerPixel = (guint) 32, _tmp0_);
if (sfVideoMode_IsValid (vm)) {
fprintf (stdout, "%d\n", (gint) cs.MajorVersion);
}
w = sfWindow_Create (vm, "Hej!", sfDefault, cs);
result = (gint) sfNone;
_sfWindow_Destroy0 (w);
return result;
}


int main (int argc, char ** argv) {
g_type_init ();
return _vala_main (argv, argc);
}





I'm getting these errors:

test.vala.c: In function ‘_vala_main’:
test.vala.c:39: error: incompatible type for argument 4 of ‘sfWindow_Create’
/usr/local/include/SFML/Window/Window.h:75: note: expected ‘const struct sfContextSettings *’ but argument is of type ‘sfContextSettings’

I don't see any sfContextSettings* there.

EDIT: Fixed again. I need to be more careful.

[Hohoo]

By the way, what's wrong with this code?

Code: [Select]

static sfWindow* sfml_window_window_new_simple (sfVideoMode mode, const char* title) {
sfContextSettings _context_settings;
g_return_val_if_fail (title != NULL, NULL);
memset (self, 0, sizeof (sfWindow));
_context_settings = sfml_window_create_context_settings ((guint) 24, (guint) 8, 0, 2, 0);
self = (sfWindow*) sfWindow_Create (mode, title, sfDefaultStyle, &_context_settings);
}

31: error: ‘self’ undeclared (first use in this function)
31: error: (Each undeclared identifier is reported only once
31: error: for each function it appears in.)
31: error: invalid application of ‘sizeof’ to incomplete type ‘sfWindow’

[Laurent]

What is self? Where is it declared?

[Hohoo]

What is self? Where is it declared?

That appeared to be a Vala bug. But it seems that self is declared on the last line.

But it seems that self is declared on the last line.

No, that's not a declaration, rather an assignment.

Sometimes it helps to carefully read the error message...
