Hi all,

I just downloaded boost and I am attempting to create a trivial program.
This my first attempt to develop boost on Fedora.  Here is what I did:

1) downloaded boost_1_45_0
2) ./bootstrap.sh
3) ./bjam toolset=gcc variant=debug link=static  --address-model=64
--with-regex

All of these step ran uneventfully

I then created a "hello world" regex program:

// regex-test.cpp
#include <string>
#include <iostream>
#include <boost/regex.hpp>

int main( int argc, char * argv[] )
{

//      boost::regex pattern
("b.lug",boost::regex_constants::icase|boost::regex_constants::perl);
        std::string stringa ("Searching for bolug");
        std::string replace ("BgLug");
        std::string newString;

//      newString = boost::regex_replace (stringa, pattern, replace);

        printf("The new string is: |%s|\n",newString.c_str());

        return 0;
}

To compile and link:
g++ -o regex-test  -I../../boost/boost_1_45_0/
-L../../boost/boost_1_45_0/stage/lib/  -lboost_regex   regex-test.cpp

If all of the boost::whatever code is commented-out then it compiles and
links fine.

[root_at_fc5-virt64 upstream]# g++ -o regex-test  -I../../boost/boost_1_45_0/
-L../../boost/boost_1_45_0/stage/lib/  -lboost_regex   regex-test.cpp
[root_at_fc5-virt64 upstream]# ./regex-test
The new string is: ||
[root_at_fc5-virt64 upstream]#

However, if I, say, uncomment-out the first line of code I get:
[root_at_fc5-virt64 upstream]# g++ -o regex-test  -I../../boost/boost_1_45_0/
-L../../boost/boost_1_45_0/stage/lib/  -lboost_regex   regex-test.cpp

Does anyone have any suggestions?
