Methods prefixed by cdecl?
Hi, I'm using Windows 7 (64 bit) and I'm trying to compile and link my code against the regex libraries. It compiles fine, but at link time, it can't find any of the methods in the regex library. But the methods it's looking for are prefixed by "__cdecl". I've tried compiling my code with the /Gd and /Gz options, and neither seemed to work. Here's what the error looks like: [ERROR] ResourceURI.obj : error LNK2019: unresolved external symbol "private: class boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > > & __cdecl 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?$w32_regex_traits@D@boost@@@boost@@@boost@@AEAAAEAV12@PEBD0I@Z) referenced in function "public: class boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > > & __cdecl boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > >::assign(char const *,char const *,unsigned int)" (?assign@?$basic_regex@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@boost@@QEAAAEAV12@PEBD0I@Z) [ERROR] ResourceService.obj : error LNK2001: unresolved external symbol "private: class boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > > & __cdecl 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?$w32_regex_traits@D@boost@@@boost@@@boost@@AEAAAEAV12@PEBD0I@Z) [ERROR] AtomicParsingExpression.obj : error LNK2001: unresolved external symbol "private: class boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > > & __cdecl boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > >::do_assign(char const *,char const *,unsigned int)" (?do_assign@?$basic_regex@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@boost@@AEAAAEAV12@PEBD0I@Z) [ERROR] AbstractLoopingVariable.obj : error LNK2001: unresolved external symbol "private: class boost::basic_regex<char,struct boost::regex_traits<char,class boost::w32_regex_traits<char> > > & __cdecl 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?$w32_regex_traits@D@boost@@@boost@@@boost@@AEAAAEAV12@PEBD0I@Z) When I do a dumpbin /symbols on the regex library I built, it does contain the methods above (as far as I can tell) 26F 00000000 SECT92 notype () External | ?assign@?$basic_regex@DU?$regex_traits@DV?$w32_regex_traits@D@boost@@@boost@@@boost@@QAEAAV1 2@PBD0I@Z (public: 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> >

Any ideas on how to get my programs to link against the methods in the regex library? Thanks, Ven

Do you compile for 64 bit? Boost and your application should be built for the same architecture.
But the methods it's looking for are prefixed by "__cdecl". I've tried compiling my code with the /Gd and /Gz options, and neither seemed to work.
/Gz is for stdcall, /Gd is for cdecl. If you do not specify either of them, then __thiscall is used for c++ member functions by default.

I'm not sure how relevant this is, but I found it interesting (from http://en.wikipedia.org/wiki/X86_calling_conventions) "Microsoft x64 calling convention... When compiling for the x64 architecture using Microsoft tools, there is only one calling convention — the one described here, so that stdcall, thiscall, cdecl, fastcall, etc., are now all one and the same."

Are you letting the auto-linking code select the correct regex .lib file to link against, or are you linking manually? I ask because those are the kinds of errors you may get if you select the wrong .lib to link to. HTH, John.

I ask because those are the kinds of errors you may get if you select the wrong .lib to link to. I'm selecting the right .lib file - libboost_regex-vc100-mt-gd-1_38.lib. We're actually using Maven to build our project, and based on the debugging output, it's pulling the right library. This is the line we used to compile the boost libraries:
bjam toolset=msvc-10.0 variant=debug link=static threading=multi stage Are there other parameters that need to be specified?
HTH, John.
Thanks, Ven

I see you are using a 64-bit build of Windows 7. Are you building a 64-bit program? If so, you need to add "address-model=64" to the bjam line. If you want to keep both 32-bit and 64-bit builds of boost, then also add "--stagedir=stage64" to keep the 32-bit and 64-bit libraries separate.
