boost:thread compiling problem
Hi Guys I am try to create a thread with boost but eveytime I execute I get some freaky error messages. See code below followed by error msg: #include <boost/thread/thread.hpp> #include <iostream> using namespace std; void hello() { cout << "hello" << endl; } int main(int argc, char* argv[]) { boost::thread thrd1(&hello); // ERROR caused by the &hello param thrd1.join(); } *Error Message*: /tmp/cc3ymRwv.o: In function `main': main.cc:(.text+0x417): undefined reference to `boost::thread::join()' main.cc:(.text+0x422): undefined reference to `boost::thread::~thread()' main.cc:(.text+0x43b): undefined reference to `boost::thread::~thread()' /tmp/cc3ymRwv.o: In function `boost::mutex::mutex()': main.cc:(.text._ZN5boost5mutexC1Ev[boost::mutex::mutex()]+0x45): undefined reference to `boost::thread_resource_error::thread_resource_error()' main.cc:(.text._ZN5boost5mutexC1Ev[boost::mutex::mutex()]+0x4d): undefined reference to `boost::thread_resource_error::~thread_resource_error()' main.cc:(.text._ZN5boost5mutexC1Ev[boost::mutex::mutex()]+0x55): undefined reference to `typeinfo for boost::thread_resource_error' /tmp/cc3ymRwv.o: In function `boost::detail::thread_data<void (*)()>::~thread_data()': main.cc:(.text._ZN5boost6detail11thread_dataIPFvvEED0Ev[boost::detail::thread_data<void (*)()>::~thread_data()]+0x16): undefined reference to `boost::detail::thread_data_base::~thread_data_base()' /tmp/cc3ymRwv.o: In function `boost::detail::thread_data<void (*)()>::~thread_data()': main.cc:(.text._ZN5boost6detail11thread_dataIPFvvEED1Ev[boost::detail::thread_data<void (*)()>::~thread_data()]+0x16): undefined reference to `boost::detail::thread_data_base::~thread_data_base()' /tmp/cc3ymRwv.o: In function `boost::condition_variable::condition_variable()': main.cc:(.text._ZN5boost18condition_variableC1Ev[boost::condition_variable::condition_variable()]+0x3a): undefined reference to `boost::thread_resource_error::thread_resource_error()' main.cc:(.text._ZN5boost18condition_variableC1Ev[boost::condition_variable::condition_variable()]+0x42): undefined reference to `boost::thread_resource_error::~thread_resource_error()' main.cc:(.text._ZN5boost18condition_variableC1Ev[boost::condition_variable::condition_variable()]+0x4a): undefined reference to `typeinfo for boost::thread_resource_error' /tmp/cc3ymRwv.o: In function `boost::detail::thread_data_base::thread_data_base()': main.cc:(.text._ZN5boost6detail16thread_data_baseC2Ev[boost::detail::thread_data_base::thread_data_base()]+0x1b): undefined reference to `vtable for boost::detail::thread_data_base' /tmp/cc3ymRwv.o: In function `boost::thread::thread<void (*)()>(void (*)(), boost::disable_if<boost::is_convertible<void (*&)(), boost::detail::thread_move_t<void (*)()> >, boost::thread::dummy*>::type)': main.cc:(.text._ZN5boost6threadC1IPFvvEEET_NS_10disable_ifINS_14is_convertibleIRS4_NS_6detail13thread_move_tIS4_EEEEPNS0_5dummyEE4typeE[boost::thread::thread<void (*)()>(void (*)(), boost::disable_if<boost::is_convertible<void (*&)(), boost::detail::thread_move_t<void (*)()> >, boost::thread::dummy*>::type)]+0x32): undefined reference to `boost::thread::start_thread()' /tmp/cc3ymRwv.o:(.rodata._ZTIN5boost6detail11thread_dataIPFvvEEE[typeinfo for boost::detail::thread_data<void (*)()>]+0x8): undefined reference to `typeinfo for boost::detail::thread_data_base' collect2: ld returned 1 exit status

You need to link to the thread library. Please read the getting started guide. In Christ, Steven Watanabe
I have read the *getting started* section and its confused me even more. 2009/8/21 Steven Watanabe <watanabesj@gmail.com>

Read it again ;-) boost::thread is a compiled library that you must link against. Be sure that you have compiled and installed the library, and that you are including the appropriate link command.

The library naming all follows a pattern, so: ~/boost/stage/lib/libboost_thread-gcc34-mt-d-1_36.a which should work if you actually built the library. - Rush
Thanks, it looks like I didnt install it properly .. below is the error message I get: *g++: ~/boost/stage/lib/libboost_thread-gcc34-mt-d-1_36.a: No such file or directory* This is what I did the install the lib. $ cd /usr/local/boost_1_39_0 $ sudo ./bootstrap.sh $ sudo ./bjam install 2009/8/21 Rush Manbert <rush@manbert.com>

I do not know if I will be able to help, but I use simple: -lboost_thread *there is L letter before boost_thread*

This is what I did the install the lib. $ cd /usr/local/boost_1_39_0 $ sudo ./bootstrap.sh $ sudo ./bjam install
bjam install places the libraries under /usr/lib bjam stage or just bjam puts the libraries in stage/lib. In Christ, Steven Watanabe
Ok, I have reconfigured it and the file is now located in the boost_1_39_0 directory. However, it still doesnt work.

You are still not using your tools correctly. -L is for specifying a directory location. The errors you are getting are because you are not linking the thread library. Let me suggest that you take some time with a simple non-boost example and learn how the compiler and linker work. The problems you are having are simply because you do not understand your tools. I am sure there must be some good tutorials on basic compiling/linking somewhere on the web.
