Re: [Boost-users] (newbie) problem using boost::regex on kubuntu 7.10

Hello,

i am new to c++ coding and for practicing i want to rewrite some of my old perl scripts that use regular expressions in c++. So i installed libboost for regex version 1.34.1 on my workstation (using a kubuntu package).

Unfortunatley even the most simple program i can think of does not want to compile:

#include <iostream> #include <cstdlib> #include using namespace boost; using namespace std;

int main(int argc, char *argv[]) { boost::regex(".*"); cout << "test\n"; return 0; }

...giving me:

[...] testapp.o: In function `boost::basic_regex >::assign(char const*, char const*, unsigned int)': /usr/include/boost/regex/v4/basic_regex.hpp:255: undefined reference to `boost::basic_regex >::do_assign(char const*, char const*, unsigned int)' collect2: ld returned 1 exit status [...]

Anyhow if i am doing

int main(int argc, char *argv[]) { boost::regex(); cout << "test\n"; return 0; }

withouth passing a regex condition it compiles successful...Yes i know this short programm does not give any meaningful functionality but i just want to demonstrate that the intialization of the basic_regex fails on my machine.

Do i have problem with my libboost installation or just a simple syntax error here?

regards
