C++11 and Code::Blocks

[MarcuzPwnz]

I can't seem to get my game to compile and run using C++11 features.

I have used the to_string() function in my code which is part of the C++11 standard.

I have told Code::Blocks to have g++ to follow C++11 ISO language standard and all I get is the following error:


I am using SFML 2.0-rc and I'm compiling with MinGW 4.6.2


Thanks.

With gcc 4.6 you have to use the -std=c++0x flag to enable support for c++11. -std=c++11 replaces that flag in version 4.7.
You could also update to 4.7, but keep in mind that you than have to recompile SFML.

Thanks, but now I just get this:

To me it look like you forgot the std:: namespace infront of to_string. But that's just a guess, because you don't show any code, so it's hard to tell...

Also you would have found the answer to both of your problems with a simple google search. Plaese google bofore you ask the next time you have a problem like that!

I was using namespace std; but I have also tried putting std:: in front of the to_string() function, this is the error it gives me:


Also if it helps, this is the function producing the error. Both cyanScore and redScore are sf::Text objects and score[0] and score[1] are integers.

Unfortunetly std::to_string and a bunch of other functions don't work with MinGW yet.
For the official branche there's an unoffical patch, which can break some code (hacen't experienced any though): here.

[MarcuzPwnz]

Oh right, I'm guessing that also means std::thread isn't supported yet either?

I'd rather just stick with the 'official' stuff for now.

As an estimate do you think to_string (and thread if it isn't supported yet) will be supported in 6 months time? or earlier?

Thanks for the responses, I really do appreciate the help.

Found it in 2 seconds with Google. You should really start to use it.

There's also a 'patch' for std::thread, but if you really want it, you might grab the MinGW-w64 rubenvb experimental build, which has support for std::thread.

Also I'm not a dev for MinGw, nor MinGw-w64, nor GCC so I can't tell you an estimate. Also the various bug reports get only pushed around.

If you want to convert a number to a string you can use this template in the meantime:

#include <sstream>
#include <string>

template <typename T>
std::string toString(const T& value)
{
    std::ostringstream oss;
    oss << value;

    return oss.str();
}

sf::String text;
text.SetText("Score: " + toString(m_score));

@Laurent, I do know about Google. Though I really do prefer talking to people over forums, I get real responses and I can continue to ask questions and learn if I'm unsure about something.

@eXpl0it3r, I'll just stick with sf::Thread for now, It seems like the easiest option for me to compile on Mac and Windows at the moment. 

@Foaly, Thanks, I did know about the string stream, someone told me about it on here before and I had a similar idea to what you posted.

Sure it's nicer to talk to real people, but you take the risk to annoy or even irritate people when the answer is already widely available on the internet.

[MarcuzPwnz]

I understand, I'll try and use Google more often.
