Hello,Sir and everybody.

OK,it worked!!
Thank you for your advice.
I'v change my test program a little.
**************************
#include <iostream>
#include <boost/regex.hpp>
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" <<endl;
}
***************************
and Makefile also,
***************************
a.out: main.o
gcc -lboost_regex -o a.out main.o
main.o: main.cpp
gcc -c main.cpp
