Dear boost programers(especially on linux/g++) :
  I copied that book's C++ Cookbook example12-1, and download boost lib's 1.46.1
on my Ubuntu Linux/ gnu-g++ system, I am not sure I am configure/install
good enough or not.  Anyway, I get a.out
but when I run a.out
-----------
eric_at_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
-------------
is this what you suppose to get?/* I email both first 2 authors: D. Ryan Stephens and Christopher Diggins, they not yet reply */
                                                      /* last 2 authors Jonathan Turkanis and Jeff Cogswell, I can not get their email address */
if not(I guess), where go wrong and how to fix it?
---------
I am pretty novice on g++ and linux.  Hope the following link help 
you debug.

http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html

I also tried
root_at_eric-laptop:/# ldconfig -p | grep -i boost
root_at_eric-laptop:/# 
--------
I read that link, it seem link will go through my /etc/ld.so.conf.d
there are 
atlas.conf GL.conf i486-linux-gnu.conf libasound2.conf libc.conf
Xen.conf

so I
cat /etc/ld.so.conf.d/libc.conf

which show
#libc default configuration
/usr/local/lib

and in my /usr/local/lib
I do have
libboost_thread.a
libboost_thread.so
libboost_thread.so.1.46.1

so I really have no idea how to debug/fix
plz help
Eric, in Los Angeles

sudo bjam install?
Alternately, just use -L/path/to/boost_1_46_1/stage/lib.

In Christ,
