Problems when linking to regex library.
In my program, I used regex library. When I build the program to the release version, everything is ok. But when I build the debug version, some link error occurs: --------------------------------------------------------------- error LNK2001: unresolved external symbol "void * __cdecl boost::re_detail::get_mem_block(void)" (?get_mem_block@re_detail@boost@@YAPAXXZ) error LNK2001: unresolved external symbol "void __cdecl boost::re_detail::put_mem_block(void *)" (?put_mem_block@re_detail@boost@@YAXPAX@Z) --------------------------------------------------------------- the tools I use: VC6 + sp5 boost_1_31_0 the regex build process: nmake -fvc6.mak nmake -fvc6.mak install Why the link error occurs? How can I fix it? --

Those symbols are only defined (and only used) when BOOST_REGEX_NON_RECURSIVE is defined, so I'm assuming that you defined that symbol for your application's debug build, but didn't do so when building the library. John.

Thanks for the clue you provide. My project linked the stlport library somedays ago. So STLP_DEBUG is defined. When I remove the stlport library from my project. I forget removing the symbol. :-( Undefine it, everything is ok. Thanks. -- that
