I\'ve been banging my head fruitlessly against the wall attempting to include boost\'s thread functionality in my Eclipse C++ project on Ubuntu.
Steps so far:
Your linker line should be saying -lboost_thread-gcc43-mt-1_38.
-lboost_thread-gcc43-mt-1_38
Well, the linker tries to find a library called "libboost_thread.a" (or "libboost_thread.so") in its search path, which you apparently don't have. Either create an appropriate link, or use "-lboost_thread-gcc43-mt"
