Problems with sf::Text

[Kim]

Hi! I have some really annoying problem I cannot figure out how to mend.
When I compile & run the application I get this error:

"Unhandled exception at 0x5105551E (sfml-graphics-d-2.dll) in codeCounter.exe: 0xC0000005: Access violation reading location 0x00000004."

Here is my class:

Code: [Select]

class Draw
{
public:
Draw(sf::RenderWindow* rw);
~Draw();

void drawBox(int comments, int rows, int chars, int blanks, int tabs);

private:
sf::RenderWindow* m_Window;
sf::RectangleShape m_Box;
sf::Font m_Font;
sf::Text m_Text;
};

Code: [Select]

void Draw::drawBox(int comments, int rows, int chars, int blanks, int tabs)
{
m_Text.setPosition(200, 200);
m_Text.setCharacterSize(15);
m_Text.setColor(sf::Color::Black);

m_Window->draw(m_Text); // if I remove this, the application work, but I wouldn't have no text!
//....
}
If I have a break-point on the m_Text it say "No information available, no symbols from sfml-graphics-d-2.dll loaded".

Anyone that know how I can mend this annoying problem? ^^

Does your text have a font?

[Kim]

I have tried with a font loaded from file, but according to the documentation it isn't required.
I have tried both with and without a font set.

Sometimes I get the error that the variable 'text' or 'font' is corrupt but I have no clue why this is happening.

[Laurent]

I have tried with a font loaded from file, but according to the documentation it isn't required.

If you use a more recent revision than 2.0 RC, the default font doesn't exist anymore.

[Kim]

Oh, OK. Then the documentation is a bit misguiding!

http://www.sfml-dev.org/documentation/2.0/classsf_1_1Text.php
"Note that you don't need to load a font to draw text, SFML comes with a built-in font that is implicitely used by default."

Anyway! I get the same error when I load a font. I even copied the font into the same folder as the code (and the debug folder).

Code: [Select]

Draw::Draw(sf::RenderWindow* rw) : m_Window(rw), m_Text("Hello World")
{
if (!m_Font.loadFromFile("arial.ttf"))
{
std::cout << std::endl << "Press Enter to shutdown..." << std::endl;
std::cin.ignore();
std::cin.get();
exit(0);
}
m_Text.setFont(m_Font); // fails here if I try to use setFont
m_Text.setPosition(200, 200);
m_Text.setCharacterSize(15);
m_Text.setColor(sf::Color::Black);
}

Code: [Select]

void Draw::drawBox(int comments, int rows, int chars, int blanks, int tabs)
{
m_Window->draw(m_Text); // fails at draw if I don't have setFont
// Code for drawing boxes below
}

What's your compiler and OS? Did you recompile SFML yourself, or did you use a precompiled version?

Oh, OK. Then the documentation is a bit misguiding!

The online doc refers to the online release. If you want the doc that matches your own version of SFML, then build it when you build SFML.

[Kim]

I use the pre-compiled version.
I use Visual Studio 2012 on a win7 machine.

[Laurent]

I use the pre-compiled version.

There's no official precompiled SFML 2.0 version for VS2012.
So... Which one is it? Where did you get it?

[Kim]

http://www.sfml-dev.org/download.php
C++ | version 2.0 RC
For 2010

[Laurent]

For 2010

That's why it crashes.
And that's why the "getting started" tutorial for Visual C++ begins with:

You must download the package that matches your version of Visual C++. Indeed, a library compiled with Visual C++ 2008 won't be compatible with Visual C++ 2005 or 2011 for example. If there's no SFML package compiled for your version of Visual C++, you will have to recompile SFML.

And when I said "If you use a more recent revision than 2.0 RC", instead of replying "the documentation is misguiding" you should have said "no, that's the version I use"...

[Kim]

I was hoping it would work when everything else works
I will be using VS2010 instead, I have it on my computer @ home ^^
I googled earlier and saw a similar problem about compiling for 2012 and you replied you didn't use it
so I guess it's easier to just setup SFML on 2010 instead and go from there ;P

Thanks for all the help!

[Laurent]

SFML is not complicated to compile.

There are also unofficial nightly builds.

So... no, you're not forced to switch to an older compiler

I only have a few days till this assignment is due, and this was the only thing still bugging me :p
So I'll try and set it up when our game-dev-assignment starts
