boost

[shisha]

Hallo unter Ubuntu ist ja Boost 1.37 noch Standard, hat sich bis 1.39 etwas so stark geändert dass es sich lohnen würde boost von hand zu installieren?

[shisha]

und noch was ich habe dieses beispiel für threads gefunden

#include <boost/thread.hpp> 
#include <iostream> 

void wait(int seconds) 
{ 
  boost::this_thread::sleep(boost::posix_time::seconds(seconds)); 
} 

void thread() 
{ 
  try 
  { 
    for (int i = 0; i < 5; ++i) 
    { 
      wait(1); 
      std::cout << i << std::endl; 
    } 
  } 
  catch (boost::thread_interrupted&) 
  { 
  } 
} 

int main() 
{ 
  boost::thread t(thread); 
  wait(3); 
  t.interrupt(); 
  t.join(); 
}

dieses kompiliert aber nicht bei mir , woran liegt das? an der version ? oder ist da ein fehler drin?

[hustbaer]

Aha. Und wir sollen jetzt raten was du für Fehler beim compilieren bekommst. Klar.

entschuldige ^^

Ich seh da keine Compilerfehler, nur Linkerfehler.
Du musst die Thread-Lib auch mitlinken.

[shisha]

sry.. kann mir einer sagen wo ich unter ubuntu die anzugebenden dateien finden kann?

[shisha]

reicht es evt wenn ich in code::blocks

folgendes hinzufüge:

/usr/local/lib

[shisha]

ich habe da echt ein problem:

ich habe gerade

../../../../../../usr/lib/libboost_date_time-mt.a

und alles was ich da gefunden habe in die linker options meines projekts rein und bekomme jetzt :

was muss ich denn genau angeben?

[otze]

wie wärs, wenn du nur die Datei, die für das threading gebraucht wird linkst? Ich glaube nicht, dass du python brauchst.
