[Boost-users] General problem on compiling a boost regex code...

Hello,

I'm using the boost library for the first time, and I get a compiler error.
:-(
I don't know why, because I think the boost library is installed successful
(I have tested the SuSE rpm file and the download version from boost.org)...
I'm using gcc 3.x and boost 1.30 on SuSE Linux 9.0...

Header file:
-------------------------------------------
#include <string>
#include <fstream>
#include <syslog.h>
#include <boost/regex.hpp>
#include <vector>

using namespace boost;
-------------------------------------------

CPP file:
-------------------------------------------
...
regex expression("([0-9]+)(\\-| |$)(.*)");
...
-------------------------------------------

Thats all I do alluded to the boost regex library... if I want to compile
the files, I get the following compiling error:

-------------------------------------------
#g++ -ansi -pedantic-errors -Wall -o statd ./projekt/statd.cpp
compiling C++ using -ansi -pedantic-errors -Wall -o statd
/tmp/cc2KYvxs.o(.text+0x1951): In function `Accounting::SaveTraffic()':
: undefined reference to `boost::reg_expression<char,
boost::regex_traits<char>, std::allocator<char>
>::reg_expression[in-charge](char const*, unsigned, std::allocator<char>
const&)'
/tmp/cc2KYvxs.o(.text+0x1994): In function `Accounting::SaveTraffic()':
: undefined reference to `boost::reg_expression<char,
boost::regex_traits<char>, std::allocator<char> >::~reg_expression
[in-charge]()'
collect2: ld returned 1 exit status
-------------------------------------------

It would be nice if someone can help me with this problem... I'm new at C++
and don't know how to fix this. :-(
If I only include the regex.hpp and do the "using namespace boost"
everything is compiling fine. Only if I do the "regex expression(...)" in
the CPP File I get the errors... :-(

Many thanks for help!
If someone will help me via ICQ: 20320644
