Although boost-1.41.0-17 is installed and I have included boost/thread.hpp in the code, I receive the this error:

undefined reference to 'boost::this_thread::disable_**interruption::disable_**interruption()

I'm using CentOS 6 and gcc compiler. Anyone knows what's causing this problem?

"Undefined references" usually indicate a linker error. Have you checked that you're linking against the thread library?

The best way to get meaningful help is to post the smallest complete source file that produces the error, and the accompanying full error message(s). Also read up on what the compiler command line options "-L" and "-l" mean, if you're not familiar with them.

thanks for the help folks. at first I tried "gcc example.cpp -o example -lboost_thread" which resulted in the following error: /usr/bin/ld: cannot find -lboost_thread collect2: ld returned 1 exit status I tried this and finally it worked: "gcc example.cpp -o example -L /root/boost_1_53_0/stage/lib/ -lboost_thread -lboost_system" I added the "/root/boost_1_53_0/stage/lib/" to Eclipse "Library Paths" on the project properties under the "C/C++ General" section and also added "boost_thread", "boost_system" , "boost_regex" and "boost_date_time" to "Libraries" on the same section. after building and compiling the undefined reference error for "boost::this_thread::disable_interruption" was removed but I received two new errors. one of them is: /usr/include/boost/thread/detail/thread.hpp:191: undefined reference to `boost::thread::start_thread()' and the other is: /root/workspace/AMI2/Debug/../src/manager/ManagerEventsHandler.cpp:46: undefined reference to `boost::thread::~thread()' in the following piece of code: #include <boost/thread.hpp> #include <boost/bind.hpp> #include <string.h> void ManagerEventsHandler::fireEvent(const ManagerEvent& me) { boost::thread t(boost::bind(&ManagerEventsHandler::internalFireEvent, this, me)); } Given that I have included "boost/thread.hpp" in the source code and included the boost::thread library path and binaries in the project, what else should I do? Mostafa I reviewed compiler options and I think I'm using them correctly. are there any flaws? Nat thanks for the link. it was very helpful.
