Custom Fonts leads to a Segmentation Fault

[MakotoYukimura]

Recently I was working on one of my Projects, and I got into writing the UI. Finally got around to adding more Fonts, however when ever I attempt to "Use" a font the program crashes with a Segmentation Fault. I have verified the font data did load, and it's there. However, when I assign an sf::String(SFML 1.6) OR sf::Text(SFML 2.1) the same issue occurs but with a slightly different outcome.

Code: [Select]

No source available for "sf::Font::GetCharacterSize() at 0xb7f4ccd4"

Even using just basic code it still occurs with the same result.

Code: [Select]

sf::Font font;
if(font.LoadFromFile("/home/mike/Bitwise BACKUP/Bitwise/Linux/Game/Graphic/Materials/WLM Grid Font Bold.ttf"))
this->m_text.SetFont(font);

The original font data is stored in a list which is assigned an ID. I changed it to this basic code to see if it was
a problem within the list. Which it wasn't.

Font Path:

Code: [Select]

/home/mike/Bitwise BACKUP/Bitwise/Linux/Game/Graphic/Materials/WLM Grid Font Bold.ttf

Here's the actual class code if it's needed.

The IDE outputed no errors on build for my project. SFML 2.1 and 1.6 seem to have the problem in the same area. After assigning the fonts it crashes.

OS Is Ubuntu 12.04 LTS running Gnome 3. Graphics Card is a 9800GT 1024mb.


Any solutions?

[Barlog]

Greetings.
Have you tried font loading with minimal basic code?
Please check if you have libfreetype installed. Just for sure.

Please try this code and let us know about outcome.

#include <SFML/Graphics.hpp>
#include <iostream>
#include <sstream>

int main()
{
    sf::RenderWindow window;
    window.create(sf::VideoMode(640, 480, 32), "font test");

    sf::Clock clock;

    std::string fontPath("/home/mike/Bitwise BACKUP/Bitwise/Linux/Game/Graphic/Materials/WLM Grid Font Bold.ttf");
    sf::Font font;
    sf::Text text;
    if (!font.loadFromFile(fontPath))
    {
        std::cout << "path is not found";
        return 0;
    }

    text.setFont(font);
    text.setCharacterSize(24);

    while(window.isOpen())
    {
        sf::Event event;

        while(window.pollEvent(event))
        {
            switch(event.type)
            {
                case sf::Event::Closed:
                    {
                        window.close();
                        break;
                    }
                case sf::Event::KeyPressed:
                    {
                        if(event.key.code == sf::Keyboard::Escape)
                        {
                            window.close();
                            break;
                        }
                    }
                    default: break;
            }
        }

        std::stringstream ss;
        std::string t;
        ss << clock.getElapsedTime().asSeconds();
        ss >> t;

        text.setString(t);

        window.draw(text);
        window.display();
        window.clear();
    }
}

That works with 1.6(after converted) and 2.1. So it seems to be project related, but I can't point to where the issue is. Since my debugger's breakpoints stopped working sometime ago(Just show up as white dots, and are disabled due to something in GDB).

[The Hatchet]

void B_BasicString::SetActiveFont ( unsigned int FONT_ID ) {

         sf::Font font;
         if(font.LoadFromFile("/home/mike/Bitwise BACKUP/Bitwise/Linux/Game/Graphic/Materials/WLM.ttf"))
                 this->m_text.SetFont(font);
}
 

After you set the active font it loses scope and is destroyed when the thread leaves this method.

[MakotoYukimura]

That's true, but even when I had a list of fonts attached that were there and constantly accessible the same thing would occur. Which is why I attempted to simplify it.

Unless I have to pass it in by Reference, then that changes everything. Because the documentation says Fonts use a lot of memory by themselves, so duplicating them may be a bad idea.

Basically, the list imports them after from the main project I call BUI_RegisterFont(<ID>, <stringpath>) and stores them in a list of registered fonts, which then are pointed towards controls. Then when I want to use a font, I retrieve it from the ID.

The list does not use Pointers, and when it did there was no difference.

However, you're correct about it being out of scope. By setting it to use a local font, the program would run properly. So I should investigate it a little more.

But I would appreciate it if SFML would atleast inform me about there being a problem with an object. I did not see anything about the "scope" being mentioned when I went to look up how to use them a while ago.

Seems to work fine now:

[eXpl0it3r]

It's in the tutorial or documentation or both.
On the other hand you understand enough of C++ to notice the by rederence pass, thus figuering out the dependency on your own. Or realize the a font is a (heavy) resource, thus you'll have to keep it around.

[MakotoYukimura]

When I got into C++ about 3 weeks ago(After coming from C# .NET) everything pretty much just fell from the sky, there was a few things though I still had to learn. Pointers, some Syntax, Etc. But now things seem to be working out quite well.

My game uses memory quite a bit, but that's due to tiles. Levels typically only load when they're about to be played, and then deallocated and deleted after they've been played - recreated again later if they want to play it again. I'm sure not going to load 2000 levels and use 12 gigs of memory, that's just not very bright. Each level contains a file that lists level parts, when the first level loads, all the level parts for that one are allocated and then played within a sequence to each other. I load them dynamically so save memory and time, it just temporarily stores the tile IDs in a 2D string array to be processed when the time comes for them to be created.

The screen res is very very small, it's 360x230(I know it's weird) but the maps are made of 20x14 tiles measured 16x16 and the game is designed to have a "Retro" feel to it.


But anyway, I did a bit of tweaking and the font list is functioning as I was wanting it too. Thanks for the help guys.

[eXpl0it3r]

Yeah managing the used memory is smart. I hope you're using the RAII paradigm instead of actually using new/delete pairs. If not you might want to read up on it, it's exactly what's going on with all of SFML's resources.

[MakotoYukimura]

Unfortunately most of the logic used for memory allocation just uses delete/new to allocate/deallocate it. I did not know about "RAII Paradigms" until you told me about it.  Even though the code itself works fine, I'll be sure to look it up.

Everything when it allocates throws exceptions or warnings if there's a problem. Exceptions will call and the engine itself will exit with a critical error message printed to console/log file to describe the problem. Warnings are usually in places that won't cause crashes and such things. I did it this way so everything will run correctly, but exceptions are only thrown if the the project is compiled with the -DEBUGGER flag. The UI Library uses code to initialize the type of safety it uses. If I tell it not to use exceptions or print messages, it will just bypass the error messages and deleting(if applicable) the bad objects. The only flaw I can really see is the objects(on load failure, or other severe errors) will commit suicide, panels are assigned to a vector which is then updated/drawn from the main loop. Each child of the panel(buttons, etc) are updated/drawn with the panel. If a Panel or a Panel's Child were to just randomly disappear, the code is written to automatically deal with it and delete it from the list of components.

My experience in C++ isn't very long, but I just know the basics of programming from C#. I learned it several years ago, while writing it in XNA. Eventually realized 'Why am I wasting my time with this'? I hated developers for not supporting Linux in the first place, yet there I was using a single platform system.

On the good side of things I corrected the debugger that was throwing a fit. But for some reason my IDE won't recognize project paths, absolute paths are necessary for some files. Which is fine, this code isn't meant to be compiled on machines that don't have same path. But I'm working on resolving it on the Eclipse support Forums under the Category "CDT".

[eXpl0it3r]

It sounds like you're doing things a bit safer than most other people out there, unfortunately there are just too much area to cover when using new/delete, so much that it isn't really possible to guarantee 100% safty. With the use of RAII and possibly some C++11 features you can drastically reduce your code base, while making memory management safe. A nice example of this can be found next to other information, in a thread by Nexus.

[MakotoYukimura]

That's a rather unique way of doing things. I'll be sure to implement it in the new objects(and future projects). The current size of the project would take days to rewrite the data. Seeing how the Level Processor class has over 5,000 lines of code. That's because the Level Builder is powered by my own version of ASM. I wanted to do something that would be fun, and not just a plain old block of chars. It also makes it a lot easier to create tiles, because it offers the ability to use basic loops.

Code: [Select]

start_level Plains
mov minx,0
mov miny,0
mov maxx,1
mov maxy,1
mov layer,2
invoke zeromode
invoke cursor_reset
mov blt,0
mov addry,0
mov addrx,0
apply addrx,13 >paste
add addry,1
apply addrx,13 >paste
res addry
res addrx
end_level

My level editor exports the map file into this code, which is read by the game itself. I guess you can say it "Compiles" data to an editable text file with an extension of .ldf

But, anyway I'll use that new way of resource management and attempt to make something safer. Thanks for the information, it may save me a lot of time and grief in near future. I am finished here, and I honestly hope I don't get more unknown problems like this in the future. I tried for 2 hours before posting here because I didn't want to post for something simple - I guess you can say it was?
