I've been able to build this program without problem on one RHEL4 machine with boost 1.33.1. But on another machine it gives a ton of errors (see below). Any thoughts would be greatly appreciated. Thanks, Ken #include <iostream> #include <string> #include "boost/regex.hpp" using namespace boost; using namespace std; int main() { string _stream("1000_===_1181763561847_===_false"); boost::sregex_token_iterator _tokens, _end; _tokens = sregex_token_iterator(_stream.begin(), _stream.end(), regex("_===_", boost::regex::literal), -1); while(_tokens != _end) { cout << *_tokens++ << endl; } } make -f sample.mak all make[1]: Entering directory `/users/sd/jbfsa/bolanosr/dci_test/DciSample' g++ -Wall -g -D__OS_LINUX__ -pthread -I../DciApi/include -I../DciApi -I../boost_release/boost -c -o DciSample.o DciSample.cpp g++ DciSample.o -L../DciApi -lDciApi -L../boost_release/libs -lboost_date_time-gcc-mt -lboost_filesystem-gcc-mt -lboost_iostreams-gcc-mt -lboost_program_options-gcc-mt -lboost_regex-gcc-mt -lboost_serialization-gcc-mt -lboost_signals-gcc-mt -lboost_thread-gcc-mt -lboost_wave-gcc-mt -o DciSample g++ -Wall -g -D__OS_LINUX__ -pthread -I../DciApi/include -I../DciApi -I../boost_release/boost -c -o TestBoost.o TestBoost.cpp g++ TestBoost.o -L../DciApi -lDciApi -L../boost_release/libs -lboost_date_time-gcc-mt -lboost_filesystem-gcc-mt -lboost_iostreams-gcc-mt -lboost_program_options-gcc-mt -lboost_regex-gcc-mt -lboost_serialization-gcc-mt -lboost_signals-gcc-mt -lboost_thread-gcc-mt -lboost_wave-gcc-mt -o TestBoost TestBoost.o(.gnu.linkonce.t._ZN5boost11basic_regexIcNS_12regex_traitsIcEESaIcEEC1EPKcjRKS3_+0x13): In function `boost::basic_regex<char, boost::regex_traits<char>, std::allocator<char> >::basic_regex(char const*, unsigned int, std::allocator<char> const&)': /usr/include/boost/regex/v4/basic_regex.hpp:340: undefined reference to `boost::reg_expression<char, boost::regex_traits<char>, std::allocator<char>
