POlinker error when using tr1::regex

copied!<p>I've got a program that uses <code>tr1::regex</code>, and while it compiles, it gives me very verbose linker errors.</p> <p>Here's my header file MapObject.hpp:</p> <pre><code>#include <iostream> #include <string> #include <tr1/regex> #include "phBaseObject.hpp" using std::string; namespace phObject { class MapObject: public phBaseObject { private: string color; // must be a hex string represented as "#XXXXXX" static const std::tr1::regex colorRX; // enforces the rule above public: void setColor(const string&); (...) }; } </code></pre> <p>Here's my implementation:</p> <pre><code>#include <iostream> #include <string> #include <tr1/regex> #include "MapObject.hpp" using namespace std; namespace phObject { const tr1::regex MapObject::colorRX("#[a-fA-F0-9]{6}"); void MapObject::setColor(const string& c) { if(tr1::regex_match(c.begin(), c.end(), colorRX)) { color = c; } else cerr << "Invalid color assignment (" << c << ")" << endl; } (...) } </code></pre> <p>and now for the errors:</p> <blockquote> <p>max@max-desktop:~/Desktop/Development/CppPartyHack/PartyHack/lib$ g++ -Wall -std=c++0x MapObject.cpp<br> /tmp/cce5gojG.o: In function <code>std::tr1::basic_regex<char, std::tr1::regex_traits<char> >::basic_regex(char const*, unsigned int)': MapObject.cpp:(.text._ZNSt3tr111basic_regexIcNS_12regex_traitsIcEEEC1EPKcj[std::tr1::basic_regex<char, std::tr1::regex_traits<char> >::basic_regex(char const*, unsigned int)]+0x61): undefined reference to</code>std::tr1::basic_regex >::_M_compile()'<br> /tmp/cce5gojG.o: In function <code>bool std::tr1::regex_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, char, std::tr1::regex_traits<char> >(__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, __gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::tr1::basic_regex<char, std::tr1::regex_traits<char> > const&, std::bitset<11u>)':<br> MapObject.cpp:(.text._ZNSt3tr111regex_matchIN9__gnu_cxx17__normal_iteratorIPKcSsEEcNS_12regex_traitsIcEEEEbT_S8_RKNS_11basic_regexIT0_T1_EESt6bitsetILj11EE[bool std::tr1::regex_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, char, std::tr1::regex_traits<char> >(__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, __gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::tr1::basic_regex<char, std::tr1::regex_traits<char> > const&, std::bitset<11u>)]+0x53): undefined reference to</code>bool std::tr1::regex_match<__gnu_cxx::__normal_iterator, std::allocator > >, std::allocator, std::allocator > > > >, char, std::tr1::regex_traits >(__gnu_cxx::__normal_iterator, std::allocator > >, __gnu_cxx::__normal_iterator, std::allocator > >, std::tr1::match_results<__gnu_cxx::__normal_iterator, std::allocator > >, std::allocator, std::allocator > > > > >&, std::tr1::basic_regex > const&, std::bitset<11u>)'<br> collect2: ld returned 1 exit status</p> </blockquote> <p>I can't really make heads or tails of this, except for the <code>undefined reference to std::tr1::basic_regex</code> near the beginning.
