boost::regex_replace compiler error

[Yahooooooooo]

Hi,

whats the issue in below code ...

#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <iterator>
#include <boost/regex.hpp>
using namespace std;

extern const char* pre= " "; // i want to remove space
extern const char* post="";

int main(void)
{
string line;
boost::regex rex1(pre);
std:stringstream osstr(std::ios:ut);
std:stream_iterator<char> osit(osstr);

ifstream fh("/tmp/log.conf");
getline(fh,line);
cout << line << endl;


boost::regex_replace(osit,line.begin(),line.end(),rex1,post,boost::match_default
| boost::format_all);

//cout <<"--"<<rex1.str()<<"--"<<endl;

fh.close();
return 1;
}

getting compiler error as below

# g++ -o runme filename.cc

/usr/include/g++/stl_uninitialized.h:71: template instantiation depth
exceeds maximum of 17
/usr/include/g++/stl_uninitialized.h:71: (use -ftemplate-depth-NN to

Is there some reason you did not do what the message told you to do?

Tried the same...

Is there some reason you did not do what the message told you to do?

Some libs of boost require a library while most can be used by just
including header files.
Regex of boost requires a library. (Build it first from sources)

The error goes away when I use following:
