--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Hubert Tong from comment #2) > I am trying to use a code base which used a TR1 regex implementation on > another platform. Your comment led me to find > http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.tr1, > which does indicate that tr1/regex does not work. It's incomplet and incorrekt. Even with those array initializers fixed that function tries to call a non-existent std::ctype::isspace() function and does (__f | __wt) when it should be (__f & __wt), and only works for char not wchar_t, and probably other issues. > Is the recommendation > (short of switching over to C++11) to use the Boost implementation? Is the > TR1 implementation status of regex in libstdc++ likely to change in the > future? The TR1 code in libstdc++ is not going to change, so if Boost is an option then yes, use that.
