General / Segmentation fault; Ubuntu 10.4 and Nvidia "current&quo

« on: May 09, 2010, 08:50:59 pm »

I recently upgraded to the latest version of Ubuntu. (32-bit, by the way.) Everything works well – except for SFML.

Only Shader, Image and Sprite were used.

SFML projects / Vala bindings have arrived!

« on: April 25, 2010, 12:06:33 am »

Get them here: http://bitbucket.org/hohoo/vala-sfml/
Or use this command:

Code: [Select]

hg clone http://bitbucket.org/hohoo/vala-sfml

They're still in an early stage (I might implement a delegate-based event system and many things may change), so if you happen to use Vala, why not try them out?

C / incompatible type for argument 4 of ‘sfWindow_Create’

« on: April 22, 2010, 02:32:28 pm »

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);
}

General / SFML2 build problems

« on: April 20, 2010, 04:11:48 pm »

I downloaded the latest SVN snapshot and tried to build it. However, all I get is loads of errors.

I'm especially interested in CSFML (I'm going to write bindings for Vala). This is what I get when I compile it:
