Hi folks,
I have:
installed eclipse on ubuntu 10.10
installed libbost 1.4 using sinaptic pkg manager
started a simple new c++ project,
#include <boost/thread.hpp>
int main(int argc, char* arg[]){
}
I tried to build it, and had the error:

blablabla...so on... a lot more errors.
what am I missing here?
I dont understand the error message, and tried to write -pthread wherever I could, but did not work. 

Any tips? detailed or stepbystep solution please, because I am a beginner, and dont understand chinese:)
thank you guys
