 Posted: Wed Apr 12, 2006 7:26 am Post subject: Boost Threading Library |
 |
|
Anybody have experience coding boost threads. I don't like pthreads because they are old school c and i need something more object oriented.
My problem is I get linker errors everytime I try to use them.
Other boost classes such as boost::shared_ptr work fine and I don't need to link to anything.
Any programmers who can help me? |

| Well, most likely I think it's because you need -lboost_thread-mt |

| shared_ptr is a template implemented entirely in a header file. There is nothing to link. |

It's probably a command line argument issue for the link command. Unlike most situations, the order of the object files and libraries on the linker command line is significant.

The other two answers are correct: most boost libraries are header only, but some end up requiring an extra library - Boost.Thread is one of them.
(Do ls /usr/lib/libboost*.so to find out all the others.)
You will also notice the "threads" and "threadsonly" USE flags for boost - make sure you at least have "threads" enabled, otherwise you won't get the -mt versions of the library, and you obviously won't get the boost threading libraries at all.
