Title: Cannot draw text, linker errors in debug mode, other in rls
Post by: alexaz on January 16, 2012, 02:38:31 pm

I cannot happen to draw text in my class. I have the following function:

Code: [Select]


void CTextRenderer::Draw(sf::RenderWindow* window){
std::map<std::string, sf::Text*>::iterator it;
for(it=members.begin(); it != members.end(); it++){
window->Draw(*(it->second));
}
}

If i run this code in debug configuration, i get the following error:

Code: [Select]


CTextRenderer.obj : error LNK2001: unresolved external symbol "public: static class sf::RenderStates const sf::RenderStates::Default" (?Default@RenderStates@sf@@2V12@B)

If i run it in release configuration, i get the following:

Code: [Select]


Unhandled exception at 0x59e04412 in SpaceCraft.exe: 0xC0000005: Access violation reading location 0x00000004.

I'v been banging my head against this and can't figure out what's the problem.

The graphics card and OS are Asus GTX470 and Windows 7, but i don't think thats relevant. I'm using the latest static sfml 2.0. I'm not showing all the relevant code, but i think that might be the problem ( sorry ). If i call the CTextRenderer::Draw from main, it will work, however if i call it from another class' instance, the following will happen.

Have you defined SFML_STATIC in your preprocessor options?

So it seems like we'll need a complete and minimal code that reproduces the problem ;)
