boost - Static Compile of Thread Example -

i compiled boost c++ libraries follows:

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

no errors. compiled following source:

#include <boost/thread/thread.hpp> #include <iostream>  #define boost_thread_no_lib  void hello() {   std::cout << "hello world, i'm thread!" << std::endl; }  int main(int argc, char* argv[]) {   boost::thread thrd(&hello);   thrd.join();   return 0; } 

using:

g++ -lboost_thread thread.cpp 

the program compiled , ran fine because boost libraries found in /usr/local/lib. when removed /usr/local/lib /etc/ld.so.conf.d/libc.conf ran following error (no surpise):

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

how compile thread.cpp linking boost statically? tried following:

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

i have following boost libraries installed:

 ldconfig -v | grep boost  libboost_unit_test_framework.so.1.41.0 -> libboost_unit_test_framework.so.1.41.0  libboost_math_tr1f.so.1.41.0 -> libboost_math_tr1f.so.1.41.0  libboost_prg_exec_monitor.so.1.41.0 -> libboost_prg_exec_monitor.so.1.41.0  libboost_math_c99.so.1.41.0 -> libboost_math_c99.so.1.41.0  libboost_regex.so.1.41.0 -> libboost_regex.so.1.41.0  libboost_signals.so.1.41.0 -> libboost_signals.so.1.41.0  libboost_python.so.1.41.0 -> libboost_python.so.1.41.0  libboost_serialization.so.1.41.0 -> libboost_serialization.so.1.41.0  libboost_graph.so.1.41.0 -> libboost_graph.so.1.41.0  libboost_date_time.so.1.41.0 -> libboost_date_time.so.1.41.0  libboost_thread.so.1.41.0 -> libboost_thread.so.1.41.0  libboost_math_c99l.so.1.41.0 -> libboost_math_c99l.so.1.41.0  libboost_math_tr1l.so.1.41.0 -> libboost_math_tr1l.so.1.41.0  libboost_wserialization.so.1.41.0 -> libboost_wserialization.so.1.41.0  libboost_system.so.1.41.0 -> libboost_system.so.1.41.0  libboost_math_tr1.so.1.41.0 -> libboost_math_tr1.so.1.41.0  libboost_math_c99f.so.1.41.0 -> libboost_math_c99f.so.1.41.0  libboost_wave.so.1.41.0 -> libboost_wave.so.1.41.0  libboost_filesystem.so.1.41.0 -> libboost_filesystem.so.1.41.0  libboost_program_options.so.1.41.0 -> libboost_program_options.so.1.41.0  libboost_program_options.so.1.35.0 -> libboost_program_options.so.1.35.0  libboost_program_options-mt.so.1.35.0 -> libboost_program_options-mt.so.1.35.0  libboost_thread-gcc42-mt-1_34_1.so.1.34.1 -> libboost_thread-gcc42-mt-1_34_1.so.1.34.1

any ideas?

try:

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

libraries must specified after objects (or sources) use symbols libraries.
