Hello,

   

    Recently I  used boost::regex in my project(VS2005 IDE). It works well with linking the lib file. But I want to use the source code of boost::regex.I include the regex.hpp in the project and used BOOST_REGEX_NO_LIB macro; But I got such error infomation when linking the code.

error LNK2001: unresolved external symbol "private: class boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > > & __thiscall boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > >::do_assign(char const *,char const *,unsigned int)" (?do_assign@?$basic_regex@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@boost@@AAEAAV12@PBD0I@Z)

I want to know why I can't use the source code of boost::regex. Is there any thing I need to do? Any help will be appreciated!

Thank you!

You're only including the header, not the source code: add the
libs/regex/src/*.cpp files to your project and you should be fine.

HTH, John.

Thus is it now possible to use only header files of regex library
without any linking?

No: that was my point, you need to either link to the library or include the
source files in your project.
