General / ZipLoader

« on: December 18, 2009, 05:47:01 pm »

Hi,

I was trying to test the exemple of the ZipLoader working with zlib and minizip.

I am not able to compile it on windows/linux.

I have downloaded zlib123.zip http://www.winimage.com/zLibDll/zlib123.zip  on linux.

I have no idea why it doesnot work.

Have any suggestions ?

Thanks

Graphics / sfml and opengl

Yeah. here is a little messy test:

Code: [Select]


#include <SFML/Graphics.hpp>

#include <iostream>
#include <fstream>

int main()
{
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "sfml");
float x = 400;
float y = 300;
App.PreserveOpenGLStates(true);
App.SetFramerateLimit(60);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0,800,600,0,-1,1);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

sf::Image texture;
if (!texture.LoadFromFile("data\\text.jpg"))
return 0;
while (App.IsOpened())
{
sf::Event Event;
while (App.GetEvent(Event))
{
if (Event.Type == sf::Event::Closed)
App.Close();
if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
App.Close();
if (Event.Type == sf::Event::Resized)
glViewport(0, 0, Event.Size.Width, Event.Size.Height);
}

glClear (GL_COLOR_BUFFER_BIT);
glLoadIdentity();
glTranslatef(x, y,0);          
texture.Bind();
glBegin(GL_QUADS);
glTexCoord2i(0,0); glVertex2f(0,0);
glTexCoord2i(1,0); glVertex2f(0,50);
glTexCoord2i(1,1); glVertex2f(50,50);
glTexCoord2i(0,1); glVertex2f(50, 0);
glEnd();
App.Display();


App.Display();
}

return EXIT_SUCCESS;
}


The code seems to work properly. But at the closing of the program i got the following message :

Code: [Select]

An internal OpenGL call failed in image.cpp (481) : GL_INVALID_OPERATION, the specified operation is not allowed in the current state
An internal OpenGL call failed in image.cpp (482) : GL_INVALID_OPERATION, the specified operation is not allowed in the current state

I did some tests and all is ok

But i have now an other problem.

I have discovered the bind method into the sf::image class.

I use it to apply some textures to my scene.

But the problem is that when i use the bind method i got some stanges messages at the closing of the program:

Code: [Select]

An internal OpenGL call failed in image.cpp (481) : GL_INVALID_OPERATION, the specified operation is not allowed in the current state
An internal OpenGL call failed in image.cpp (482) : GL_INVALID_OPERATION, the specified operation is not allowed in the current state


My code is the following :

Code: [Select]



//Initalization//
sf::RenderWindow App(sf::VideoMode(WIDTH, HEIGHT), "SFML OpenGL");
App.PreserveOpenGLStates(true);
App.SetFramerateLimit(60);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0,WIDTH,HEIGHT,0,-1,1);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();        

if (!this->_texture->LoadFromFile("img\\2.bmp"))
//except


//render func
      glClear (GL_COLOR_BUFFER_BIT);
  glLoadIdentity();
glTranslatef(this->getX(), this->getY(),0);
this->_texture->Bind();
glBegin(GL_QUADS);
glTexCoord2i(0,0); glVertex2f(0,0);
glTexCoord2i(1,0); glVertex2f(0,50);
glTexCoord2i(1,1); glVertex2f(50,50);
glTexCoord2i(0,1); glVertex2f(50, 0);
glEnd();
App.Display();




Thanks

Now the compilation and linkage  work.

But i have always the problem at the closing of the program.

Here is a picture to show you :

ok. Thanks.

I added opengl32.lib.
Some problems were solved but there are always this one :

Code: [Select]

Error 1 error LNK2001: unresolved external symbol _gluPerspective@32 main.obj
Error 2 error LNK2001: unresolved external symbol _gluBuild2DMipmaps@28 main.obj


Do you have an idea ?

Oki. Thanks for your answer.

But where can i find this lib ?

The website of opengl is not very efficient to found something...

hello.

I'm discovering sfml lib and i would like to be able to use opengl.

I pasted the code of the tutorial (http://www.sfml-dev.org/tutorials/1.5/window-opengl-fr.php).

I was not compiling because of errors during the linkage.

Code: [Select]


Error 1 error LNK2001: unresolved external symbol __imp__glDeleteTextures@8 main.obj
Error 2 error LNK2001: unresolved external symbol __imp__glClearDepth@8 main.obj

So i downloaded the glut lib found there : http://www.xmission.com/~nate/glut.html

I was surprising to see that the lib was very old (2001... !!!).

Then, i added this include to the code.

which redirect to what i downloaded.

#include <gl/glut.h>

And, miracle, the compilation works.

Is all i did is right ? Did i did anything wrong ?

Because when i stop the application, it crash.

I breakpoint the executation, i saw the error was after the main return.

If anybody has any idea ?

Thanks


Ps. I'm working with Seven and VisualStudio 2008
