i cannot tell why i am having trouble with basic_regex.  I followed the installation instructions and had no error on install. 


g++ -o example -g -O2 -Wall -W -Wno-unused -fno-strict-aliasing   example.cc -lboost_regex
/tmp/ccFmlTDD.o(.text+0x3c): In function `main':
/usr/local/include/boost/regex/v4/basic_regex.hpp:253: undefined reference to `boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::do_assign(char const*, char const*, unsigned)'
collect2: ld returned 1 exit status

example.cc:
#include <boost/regex.hpp>
using namespace boost;
int main () {
   regex expr("foo");
   return 0;
}

i compiled and installed boost as follows:
./tools/build/jam_src/bin.linuxx86/bjam -sHAVE_ICU=1 -sICU_PATH=/usr/local/share/icu/3.6 -sTOOLS=gcc -sPYTHON_ROOT=/usr -sPYTHON_VERSION=2.4 --prefix=/usr/local --exec-prefix=/usr/local --libdir=/usr/local/lib --includedir=/usr/local/include  install


thanks for any help
