General / Undefined references when linking statically

« on: May 13, 2011, 08:05:48 am »

Which is for dynamic link, not static

It may not have been clear what I was trying to say but I only used the define when I compiled dynamically

Switching the path under Settings -> Compiler and debugger... -> Global compiler settings -> Toolchain executables -> Compiler's installation directory to the path of the MingW version you suggest in the tutorial makes it work flawlessly for static linking I also managed to circumvent the fps issues (very low delta-times) I experienced on my laptop a while back. Maybe I need to update my drivers or OpenGL version?

Anyway, thank you for your help

General / Undefined references when linking statically

« on: May 12, 2011, 12:02:31 am »

I am trying to link SFML 1.6 to my project in Code::Blocks 10.05 with MingW 4.4.1

I followed this tutorial and used the same source code used as an example.

I am getting the following errors:

Code: [Select]


||=== SFML_test, Debug ===|
E:\Tools\SFML\SFML-1.6\lib\libsfml-system-s-d.a(Clock.o):Clock.cpp:(.eh_frame+0x11)||undefined reference to `__gxx_personality_v0'|

I know this question has probably been asked a dozen times or more but before posting I: Reread the tutorial, searched the internet and double-checked the settings/options in Code::Blocks.

Additionally, I added the SFML_DYNAMIC define and "-lsfml-system-s-d" and copied "libgcc_s_dw2-1.dll" and "sfml-system-d.dll" to my project executable's directory and got it to work (in Debug configuration). I should also mention that "libgcc_s_dw2-1.dll" was to located in the MingW version I have (found "libgcc_s_sjlj-1.dll" instead). I got this .dll from the download suggested in the beginning of the tutorial. I still want to make it work with the static libraries though

Graphics / GetFrameTime returns values in the order of 0.15 seconds

It's just updating which images should be drawn and so on. I already tried commenting out the Update function without any success. I am beginning to think the problem maybe lies in the versions of OpenGL (no idea..)/SFML (1.6)?

I will continue to look through the code and test it out.

Thanks for your input so far

Graphics / GetFrameTime returns values in the order of 0.15 seconds

I checked my code again and I don't see that I am copying images anywhere.

Here's the updating and drawing part of my Game class:

Code: [Select]


void Game::Think()
{
if(States.back())
States.back()->Update(renderWindow.GetFrameTime());
}


Code: [Select]


void Game::Draw()
{
renderWindow.Clear();

if(States.back())
{
if(States.back()->IsPopup() && States.size() > 1)
{
if(States[States.size() - 2])
States[States.size() - 2]->Draw();
}

States.back()->Draw();
}

renderWindow.Display();
}


and the loading of the IntroState class (checked that it is only called once):

Code: [Select]


bool IntroState::Load()
{
if(!Fader.LoadFromFile("./Graphics/Images/Fader.png"))
return false;

if(!StormGamesLogo.LoadFromFile("./Graphics/Images/StormGamesLogo.png"))
return false;

if(!SfmlLogo.LoadFromFile("./Graphics/Images/SDLlogo.png"))
return false;

if(!LuaLogo.LoadFromFile("./Graphics/Images/StormGamesLogo.png"))
return false;

FaderSprite.SetImage(Fader);
StormGamesLogoSprite.SetImage(StormGamesLogo);
SfmlLogoSprite.SetImage(SfmlLogo);
LuaLogoSprite.SetImage(LuaLogo);

FaderSprite.SetColor(sf::Color(255, 255, 255, alpha * 255));

return true;
}

I'm using a type of state management where each state is a mini-application. The Game class manages a std::vector<GameState*> container. Hope it all makes sense

Graphics / GetFrameTime returns values in the order of 0.15 seconds

Hi Groogy,

One of the images is just black and I simply change its alpha value. I tried commenting out the update function which changes the alpha value, but it did not improve. If it has any relevance, I'm changing the alpha value with the following call:

Code: [Select]


FaderSprite.SetColor(sf::Color(255, 255, 255, alpha * 255));

Graphics / GetFrameTime returns values in the order of 0.15 seconds

Hi all,

First up, I would like to congratulate the creators of SFML on a very good job!

This is my first time using SFML. I have had experience with SDL (+OpenGL) and C#/XNA. I am using MSVC++ 2008 on a laptop (Graphics: Mobile Intel(R) 965 Express Chipset Family and Processor: Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz)

Anyways, I tried creating a small intro to a space shooter (with logos fading in and out etc.). I create 4 images and 4 sprites and set each image to their respective sprite. The code was taken from another project of mine.

I ran the program and saw that it was running very slowly. I printed out the values returned by RenderWindow::GetFrameTime() and they were in the order of ~0.15 seconds. I tried running it in Release mode, but only got a small improvement at ~0.13-0.14 seconds. I then tried copying the executable to my gaming computer and the values were on the order of ~0.001 (that computer just broke down just now though but I'm pretty sure it was around those values).

It seems my computer is too slow, but I can run games like WC3 and SDL + OpenGL projects without issues. Maybe there is another problem?

I tried commenting out my draw code and the speed went up to the order of running in Release mode. Here is my drawing code (I used to pass a reference to my render window, but that is now public/static for global access):

Code: [Select]


if(currentLogo == 1)
Game::renderWindow.Draw(StormGamesLogoSprite);
else if(currentLogo == 2)
Game::renderWindow.Draw(SfmlLogoSprite);
else
Game::renderWindow.Draw(LuaLogoSprite);

Game::renderWindow.Draw(FaderSprite);
