RE: [Boost-users] building boost on vc7.1 with stlport

Hmm... In all the tests I ran I think I forgot to remove that library (I was forcefully adding it for some reason). Now I'm exactly where I was at the beginning: when I compile my program I get these 2 linker errors: html to mhtml error LNK2019: unresolved external symbol "public: __thiscall boost::reg_expression::reg_expression(char const *,unsigned int,class _STL::allocator<char> const &)" (??0?$reg_expression@DV?$regex_traits@D@boost@@V?$allocator@D@_STL@@@boost@@ QAE@PBDIABV?$allocator@D@_STL@@@Z) referenced in function "public: __thiscall boost::basic_regex::basic_regex(char const *,unsigned int,class _STL::allocator<char> const &)" (??0?$basic_regex@DV?$regex_traits@D@boost@@V?$allocator@D@_STL@@@boost@@QAE @PBDIABV?$allocator@D@_STL@@@Z) html to mhtml error LNK2019: unresolved external symbol "public: __thiscall boost::reg_expression::~reg_expression(void)" (??1?$reg_expression@DV?$regex_traits@D@boost@@V?$allocator@D@_STL@@@boost@@ QAE@XZ) referenced in function "public: __thiscall boost::basic_regex::~basic_regex(void)" (??1?$basic_regex@DV?$regex_traits@D@boost@@V?$allocator@D@_STL@@@boost@@QAE @XZ) I get them both in release and debug with wchar_t support both on and off and the multithreaded library linked (release or debug) and without dlls (i.e. /MT and /MTd). The 2 functions above SEEM to be in regex_compile.cpp and they get included (I put a #error in the middle of the function) but it never links... ---------------------------------- Peace and love, Tweety mitea@sympatico.ca - tweety_04_01@users.sourceforge.net YahooID: tweety_04_01

...

1. I built stlport 2. I set STLPORT_PATH and STLPORT_VERSION to their respective paths 3. I replaced every occurrence on /Zc:wchar_t with nothing (practically deleting them) -- you should write this somewhere on your page... 4. I went to libs/regex/build 5. I ran nmake /f vc71-stlport.mak all (it went ok this time, no errors) 6. I ran nmake /f vc71-stlport.mak install (and it all went ok).

Now I make a simple win32 app and I include . But when I actually USE the regex class I get this linker error:

html to mhtml fatal error LNK1181: cannot open input file 'libboost_regex-vc71-s-1_31.lib'

And it is not there... What am I missing? Do I need to make a copy or something? I get that error regardless of my program's wchar_t setting (although I'll leave it off for now) or the runtime library (I'll leave that /MT).

Now this is a step forward (albeit small). Now I just need to get my program compiling. Can you help?

Yes: the library 'libboost_regex-vc71-s-1_31.lib' is the following variant:

Release runtime library. Single threaded. Static runtime library. *Not* an STLPort build.

So:

1) your app is apparently not being built with STLPort in it's include path, and given the subject line I assume you want it to be. 2) STLPort does not support the single threaded runtime out the box, so you will have to switch to one of the multithreaded runtimes. 3) If you use a debug runtime, then I suspect you will also have to define __STL_DEBUG when building as that's the STLPort setting that Boost uses by default.
