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@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@fc5-virt64 upstream]# ./regex-test
The new string is: ||
[root@fc5-virt64 upstream]#
However, if I, say, uncomment-out the first line of code I get:
[root@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?
