thank you for your reply.
I'm the user ;-)
1)How could i figure out which directory is set by CMAKE_MODULE_PREFIX ?
2)How could i set it to the right directory?

C / CMAKE failure

« on: August 09, 2016, 09:49:31 pm »

Hi,

i'd like to generate build files with cmake. It generates this failure:

CMake Error at src/SFML/CMakeLists.txt:28 (find_package):
  By not providing "FindSFML.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "SFML", but
  CMake did not find one.

  Could not find a package configuration file provided by "SFML" (requested
  version 2) with any of the following names:

    SFMLConfig.cmake
    sfml-config.cmake

  Add the installation prefix of "SFML" to CMAKE_PREFIX_PATH or set
  "SFML_DIR" to a directory containing one of the above files.  If "SFML"
  provides a separate development package or SDK, be sure it has been
  installed.

I don't understand the reported solutions:
1) Where is the CMAKE_MODULE_PATH to put the "FindSFML.cmake" into?
2) How could i add the installation prefix of "SFML" to CMAKE_PREFIX_PATH?
3) Where are the directory of the files SFMLConfig.cmake and sfml-config.cmake?

I am very thankful for every solution.

Is it the actual code that gives you the error, or is it a simplified version for the forum, that you never compiled?

Thank you very much! I forgot to declare the prototype...

C / Re: set up Eclipse CDT for CSFML, error while loading shared libraries

« on: April 27, 2016, 07:55:30 am »

Something like this below?

sudo nano /etc/ld.so.conf.d/myapp.conf

  GNU nano 2.2.6                         Datei: /etc/ld.so.conf.d/myapp.conf                                                        

/home/u123/Programme/TestpProg/sfmlStuff/SFML-2.2/lib
 

and after this ldconfig and reboot generate the same failure

Hi,

I use Kubuntu 14.04, Eclipse CDT and like to include CSFML which generate this error:

And the error would be...?

// throws error: request for member top in something not a structure or union      
floatRect.top = sfFloatRect_set(1,1,1,1).top;

With the exception of main's return type being int (google why).

i fixed it in the main post but my code still throw the same error

C / sfFloatRect_set function

« on: April 26, 2016, 03:24:47 pm »

Hi this works fine:

#include <SFML/Graphics.h>

sfVector2f sfVector2f_set(float x, float y){
        sfVector2f vector2f;

        vector2f.x = x;
        vector2f.y = y;

        return vector2f;
}

int main(){
sfVector2f vector;
vector.x = sfVector2f_set(1, 1).x;
}
 

But this throws error: request for member top in something not a structure or union

#include <SFML/Graphics.h>
sfFloatRect sfFloatRect_set(float top, float left, float width, float height){
        sfFloatRect floatRect;

        floatRect.top = top;
        floatRect.left = left;
        floatRect.width = width;
        floatRect.height = height;

        return floatRect;
}

int main(){
sfFloatRect floatRect;

// throws error: request for member top in something not a structure or union      
floatRect.top = sfFloatRect_set(1,1,1,1).top;              
                                                       
}
 

I think it could be a basic c problem but i'm very thankful for a reason.

C / sfRenderWindow as function argument

« on: April 26, 2016, 12:20:14 pm »

Hi,

this works fine:

#include <SFML/Graphics.h>
#define SCREENWIDTH 1000
#define SCREENHEIGHT 1000
#define BITSPERPIXEL 32

sfRenderWindow* sf_init()
{
        sfVideoMode mode =
                        { SCREENWIDTH, SCREENHEIGHT, BITSPERPIXEL };

        /* Create the main window */
        return sfRenderWindow_create(mode, "SFML window", sfResize | sfClose, NULL);

}

void main(){
       sfRenderWindow* window = sf_init();
}
 

But why doesn't work this:

#include <SFML/Graphics.h>
#define SCREENWIDTH 1000
#define SCREENHEIGHT 1000
#define BITSPERPIXEL 32

void sf_init(sfRenderWindow *window)
{
        sfVideoMode mode =
                        { SCREENWIDTH, SCREENHEIGHT, BITSPERPIXEL };

        /* Create the main window */
        window = sfRenderWindow_create(mode, "SFML window", sfResize | sfClose, NULL);

}
void main(){
        sfRenderWindow* window;
        sf_init(window);
}
 

Any ideas into where the problem lies? Thanks.
