Network / undefined reference

« on: November 07, 2014, 12:43:40 pm »

Hello. I  read the documentation(Connecting a TCP socket) and this is my code:

#include <SFML/Network.hpp>

using namespace std;

int main()
{
    sf::TcpSocket socket;
    sf::Socket::Status status = socket.connect("192.168.0.5", 53000);
    if (status != sf::Socket::Done)
    {
        // error...
    }
    return 0;
}

I have the newest version of codeblocks:codeblocks-13.12mingw-setup-TDM-GCC-481.exe

What can I do to run the code?

System / Re: Pass paramater/argument's address to thread's function which is in class in SFML

Thank you wintertime and everybody who wrote it this topic. I reinstalled the whole IDE with TDM-GCC-481 and it worked.

System / Re: Pass paramater/argument's address to thread's function which is in class in SFML

I am with windows 7, codeblocks, GNU GCC Compiler. I have seen that there are more people that have the same problem as mine. From codeblocks but I can`t turn on C++11. I checked it true from Settings->Compiler and from project->Build Options but it messages:

thread is not member of std

This is for example the code:

// thread example
#include <iostream>       // std::cout
#include <thread>         // std::thread
 
void foo()
{
  // do stuff...
}

void bar(int x)
{
  // do stuff...
}

int main()
{
  std::thread first (foo);     // spawn new thread that calls foo()
  std::thread second (bar,0);  // spawn new thread that calls bar(0)

  std::cout << "main, foo and bar now execute concurrently...\n";

  // synchronize threads:
  first.join();                // pauses until first finishes
  second.join();               // pauses until second finishes

  std::cout << "foo and bar completed.\n";

  return 0;
}

The administrator of codeblocks` forum said and you can see more here - http://forums.codeblocks.org/index.php?topic=17838.0;prev_next=prev:

We do not build vompilers just an IDE, that works with many compilers.
We ship with a TDM's gcc on windows to make it easy to start coding for beginners (and most other users) without the need to explicitely download a compiler.
So you as user are free to use any supported compiler, with or without std:thread-support.

He answered to someone who said:

oh my bad Sad that's really freaking. Ok I have than to swap to Linux partition.
is there any chance to add support for std::thread ever in GCC at this point?

What can I do to change my compiler or?

System / Pass paramater/argument's address to thread's function which is in class in SFML

« on: November 01, 2014, 10:15:19 am »

Hello. I am wondering is this possible to pass parameter or argument`s address and get it with reference operator or with pointer in thread's function which is in class with SFML System Class. Can I send the value of argument too? I have read that is better to use C++ ISO 11. Is there something new with threads in C++ ISO 14?
Something like this:

#include <SFML/System.hpp>
#include <iostream>
using namespace std;
class MyClass
{
public:

    void func(int & argument or int * argument or int argument)
    {
//make something with this argument for example ++argument or ++*argument or print it with cout  
    }
};
int main()
{
int argument = 0;

MyClass object;
sf::Thread thread(&MyClass::func, &object, (argument or &argument or argument  ));
thread.launch();
return 0;
}
 

Thank you. Have a nice day.
