Hi all,
I have the following code to validate a given url using boost::regex. The
code is failing linking with g++ 3.3.2, but is building with 3.4.5
Any workaround, or pointer to help to build in 3.3.2? I am on boost 1.32.
All the linking errors are related to std strings.
#include <iostream>
#include <string>
#include // Boost.Regex lib
using namespace std;
int main( )
{
std::string url("http://myserver:80/index.html");
boost::regex re;
try
{
boost::regex
re("(ftp|http|https):\/\/(\w+\.)*(\w*)\/([\w\d]+\/{0,1})+");
if (!boost::regex_match(url, re))
{
throw "Your URL is not formatted correctly!";
}
}
catch (...)
{
cerr << "The regexp " << re << " is invalid!" << endl;
}
}
g++ regex2_url.cpp /usr/lib/libboost_regex.a
