Link problem about boost with g++

[doudehou]

First of all, I just made a mistake to post the message in
gun.gcc.help...
So I re-post it here. I think it will not off-topic now:-)


Below is a description about the problem:
Today, I downloaded the lastest version of boost. And compiled it with
my minGW(the version of g++ is 3.4.2). The compile command I used is
"bjam -sTOOLS=mingw --prefix=D:\3rd\boost install ". So all the
compiled .libs and the header files are placed in D:\3rd\boost. And I
set environment variant
CPLUS_INCLUDE_PATH=d:\3rd\boost\include\boost-1_34.

Then I wrote two short programs to test the new built boost.

The first was to test boost::shared_ptr, because shared_ptr refer no
.lib, so it passed the compilation.

The second is to test boost::regex. it need a link of some boost .lib.
But g++ report a link error when compiling.
I used "g++ rx.cpp -L D:\3rd\boost\lib -o rx" to generate the .exe.

The compile 's error message is:

I think the problem is that g++ didn't know which .lib it should used
to generate the .exe file. But how to set it ? I don't want to add the
proper .lib name in the compile command everytimes.

Thank you very much for your help !
