statique Compile de fil Exemple

Question

Je compilé les bibliothèques Boost C++ comme suit:

bjam install variant=release link=static threading=multi runtime-link=static 

Aucune erreur. Ensuite, je compilé la source suivante:

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

#define BOOST_THREAD_NO_LIB 

void hello() { 
    std::cout << "Hello world, I'm a thread!" << std::endl; 
} 

int main(int argc, char* argv[]) { 
    boost::thread thrd(&hello); 
    thrd.join(); 
    return 0; 
} 

utilisant:

g++ -lboost_thread Thread.cpp 

Le programme compilé et a fonctionné très bien parce que les bibliothèques Boost se trouvent dans /usr/local/lib. Quand j'ai enlevé /usr/local/lib de /etc/ld.so.conf.d/libc.conf je suis tombé sur l'erreur suivante (pas surpise):

./a.out: error while loading shared libraries: libboost_thread.so.1.41.0: cannot 
open shared object file: No such file or directory 

Comment compiler un lien vers Thread.cpp Boost statique? J'ai essayé les éléments suivants:

g++ -static -lboost_thread -lpthread Thread.cpp 

Je les ai suivantes bibliothèques Boost installé:

Toutes les idées?

Answer 1

Essayez:

g++ -static -pthread Thread.cpp -lboost_thread 

Les bibliothèques doivent être spécifiés après les objets (ou sources) qui utilisent des symboles de ces bibliothèques.
