      Hello,Sir and everybody.
...
Presumably you need to add the -lboost_regex to your linkers command line.
OK,it worked!!
Thank you for your advice.
I'v change my test program a little.
**************************
#include <iostream>
#include 
using namespace std;
using namespace boost;

int main()
{
        const char* re ="[0-9](.*)";
        regex expression(re);
        const char* str= "1234567890";
        cmatch what;
        regex_match(str,what,expression);
        cout << "success" < wrote:

Hi, from Japan.I'm pretty new to c++ and I'm trying to work out on
regex. When I compile these lines,it ends with "undefined reference
to ..." Please let me know how to use regex properly.
I use on FC4 and newest boost version,compiling in Anjuta.
You don't say what compiler you're using?
Presumably you need to add the -lboost_regex to your linkers command line.
Note also that [0-9] will only match the first character of "1234567890" so 
the call to regex_match will fail (regex_match requires that the whole of 
the text is matched in order to succeed).  Use regex_search if you want to 
match a sub-string of the text.
John.
