Dear Jeffrey (and/or gnu/g++ programers):
  I follow your hint
--------------------
root@eric-laptop:/# ldconfig -p | grep -i boost
root@eric-laptop:/# 

----------
so it looks my thread lib is not available for the runtime linker
although your first commnad do issue a.out without compile/link error
however, when I run ./a.out
---------
eric@eric-laptop:~/cppcookbook$  ./a.out
./a.out: error while loading shared libraries: libboost_thread.so.1.46.1: cannot open shared object file: No such file or directory
--
that looks not what the book author suppose it be.
(so I emailed first author of that book, D. Ryan Stephens, he is not yet reply me)
looking to see better way to make it work right, and thanks a lot in advance, Eric

It it does not link, issue the following to see if the library is
available to the runtime linker
    ldconfig -p | grep -i boost

This isn't the right place to find out how to install boost - read the
boost website.  Or if you're using GNU/Linux you can probably install
it from your distro's package manager, that would be easiest.

It's the name of a library, -lboost_thread-mt tells the linker to link
to libboost_thread-mt.so

The file will be called libboost_thread-mt.so

Re: boost library, hardtolink&compile, plz help

[eric lin]

Dear Jonathan or any g++ programers:
  after reading your email hint, I goto my download and extracted directory
/boost1_46_1/  directory
and then run
./bootstrap.sh

I don't know whether that is what you mean about ((install boost library) and (if it is where is boost library go))

then after that I run your suggest command in my cppcookbook/ directory which contain my example program about using boost lib's thread

this is what I do and get
------------------------
eric@eric-laptop:~/cppcookbook$ g++ -I/home/eric/boost1/boost_1_46_1/ example12-1.cpp  -L/home/eric/boost1/boost_1_46_1/boost/   -lboost_thread-mt
/usr/bin/ld: cannot find -lboost_thread-mt
collect2: ld returned 1 exit status
eric@eric-laptop:~/cppcookbook$ 

-----------------------------------
would you please tell me what is

boost_thread-mt

mean?

if that is a file, I indeed hard to find it in my /boost_1_46_1/  directory

thanks your help a lot, but still not solve

No, you didn't understand.  -L is used to name a directory where
libraries live, like -I is used to name a directory where headers
live.

Have you build the boost libraries yet?
If you haven't then you need to do that first.

Then do

g++ -I/home/eric/boost1/boost_1_46_1/ example12-1.cpp
-L/path/to/boost/libraries -lboost_thread-mt

I think typically boost "packages" that have a run-time component (many
don't) each has its own library.

For instance, on this system, the boost thread package needs to be
linked against like "-lboost_thread-mt".

These errors, from the linker, mean that you are not linking against the
Boost library.  You need to add something like -lboost with some -L
option which points to the directory where libboost.so or libboost.a can
be found.

I strongly doubt you copied that from a book. You should have:
#include <boost/thread/thread.hpp>

and compile with g++ -I/home/eric/boost1/boost_1_46_1 ...
