Undefined reference to boost::timer::auto_cpu_timer
boost, c++, compiler-construction
Solution
You need to link against boost_timer. Add `-lboost_timer` to the gcc command line. Consult the Netbeans documentation on how to add libraries to a project.
Problem
I try to compile small .cpp file with boost library on remote server on Debian using g++ 4.4. I use Netbeans for this purpose. My home machine is on windows 7. After resolving some issues with linking next code ``` #include <boost/timer/timer.hpp> #include <iostream> #include <string> int main() { boost::timer::auto_cpu_timer ac; //line 5 return 0; //line 6 } ``` Produces 2 errors: line 5: `undefined reference to boost::timer::auto_cpu_timer::auto_cpu_timer(short)'` line 6: `undefined reference to boost::timer::auto_cpu_timer::~auto_cpu_timer()'` Same result if i use header `boost/thread.hpp` but for thread constructor/destructor. But for example `boost/shared_ptr` compiles without any problem. Result compile command in neatbeans is ``` g++ -m64 -I/usr/include/boost/boost_1_49_0 -lboost_system -o dist/Debug/GNU-Linux-x86/test build/Debug/GNU-Linux-x86/main.o -L/usr/include/boost/boost_1_49_0/stage/lib -Wl,-rpath /usr/include/boost/boost_1_49_0/stage/lib build/Debug/GNU-Linux-x86/main.o ``` What i missed?
