I'm using boost library for regular expression, I used boost::regex() function to compile the regular expression. I have to catch the exception thrown by this function call. So I used boost:regex_error in catch().

But the use of this function gives following error:

undefined symbol: _ZTIN5boost11regex_errorE

What is the reason of above error?

  • You need to link with the boost regex library (which you will have to build first). – hmjd Aug 16 '12 at 10:18

You have to link with boost_regex. On GCC, add -lboost_regex to your linker invocation. Other compilers will have equivalent options.

$ c++filt _ZTIN5boost11regex_errorE
typeinfo for boost::regex_error

So typeinfo is missing. I think you should compile your project with RTTI (run time type information) enabled.

or

g++ undefined reference to typeinfo
