Hello ,every one.
I got undefefined reference errors while using thread libs, I reviewd
some existing post
on this subject, but still can't solve my problem.
So I paste my problem here, I appreciate any help. Thank you.
My platform is fedora 8, gcc  4.1.2 20070925 (Red Hat 4.1.2-33).
I downloaded boost_1_37_0.tar.bz2 from www.boost.org
I followed the "Getting started guide" on the www.boost.org
I extracted the boost_1_37_0.tar.bz2 use "tar --bzip2 -xf
/usr/local/boost_1_37_0.tar.bz2";
Because I want to write multi-thread programs using boost, so I
decided to build the separately-compiled Boost libraries.
I followed the "Getting Started Guide".
I run the following cmds:
 ./configure --prefix=/usr/local/boost_1_37_0/
 make install
So, after long wait, it's done, all the librarys are build.
My /usr/local/boost_1_37_0 directory structure looks like this:

----------------------------------------------------------------------------------
I test the regex library by running the program from the "Getting
Started Guide", which links the regex library.
I named the program regex.cpp.
Following is the cmd I used to compile the program.
"c++ -I /usr/local/boost_1_37_0 regex.cpp -o regex
/usr/local/boost_1_37_0/lib/libboost_regex-gcc41-mt-1_37.a"
There is no error occurs.

Then, I write another program trying to use the thread library.
I named this program thre.cpp.
Following is my program, a  very simple one:
-----------------------------------------------------------------------------
#include <boost/thread.hpp>
#include <iostream>
void hello()
{
        std::cout<<std::endl<<"hello world, I'm a thread!"<<std::endl;
}
int main()
{
        boost::thread thrd(&hello);
        thrd.join();
        return 0;
}
------------------------------------------------------------------------------------
Then I compile it use the following cmd, very similar to  the previous one
" c++ -I /usr/local/boost_1_37_0 thre.cpp -o thre
/usr/local/boost_1_37_0/lib/libboost_thread-gcc41-mt-1_37.a"
but I got the following errors:

But in fact ,in the lib directory , there exist the thread libs, they are:
-------------------------------------------------------------------------------------

/usr/local/boost_1_37_0/lib/libboost_thread-gcc41-mt.so

-------------------------------------------------------------------------------------

I also tried another cmds on these two programs, they are:
"g++ -o regex -lz regex.cpp
/usr/local/boost_1_37_0/lib/libboost_regex-gcc41-mt-1_37.a"
"g++ -o thre -lz thre.cpp
/usr/local/boost_1_37_0/lib/libboost_thread-gcc41-mt-1_37.a"

the regex cmd runs ok, but the thre cmd again failed. Got the following errors:

I attatched my makefile, hope it give some cues.

Thank you for your patience reading so long a post.
