FW: Linker errors when using regex Lib with MSVC8 and STLPort 5.1.0 and Boost 1_33_1
Hi I have built the StlPort 5.1.0 shared dlls and boost 1_33_1 Shared dlls successfully. The Platform is MSVC8. I created a sample projeth with just on file with code: #include <boost/regex.hpp> bool testregex( const char* StringToMatch ) { return( boost::regex_match( StringToMatch, boost::regex("[A-Z]+") )); } int main (int argc, char *argv[]) { bool trial = testregex( "hello how r u ?"); return 1; } Compilation succeeds but I get two Linker errors (BOOST_DYN_LINK is defined) Main.obj : error LNK2001: unresolved external symbol "public: bool __thiscall boost::re_detail::perl_matcher<char const *,class stlp_std::allocator<struct boost::sub_match<char const *> >,struct boost::regex_traits<char,class boost::w32_regex_traits<char> >

Those are typically the errors you get when linking against Boost libraries that were *not* also built against STLport.
2) add regex source code and compile ( using BOOST_REGEX_NO_LIB) : I get the errors for stdext namespace
1>C:\boost_1_33_1\boost/regex/v4/regex_workaround.hpp(145) : error C2653: 'stdext' : is not a class or namespace name
That's very strange: that section of code is protected with: #if BOOST_WORKAROUND(BOOST_MSVC,>=1400) && defined(_CPPLIB_VER) && !(defined(__SGI_STL_PORT) || defined(_STLPORT_VERSION)) So should never be taken when STLport is in use. I'm not able to reproduce this either using STLport 5.1 and VC8. What specific compiler options are you using and which file generated this error? Thanks, John.

I looked again, and apparently this was a bug in 1.33.1 that's been fixed in cvs, try downloading the latest version of regex_workarounds.hpp from here: http://boost.cvs.sourceforge.net/boost/boost/boost/regex/v4/regex_workaround... and see if that fixes things. John.
Hi John Thanks for the replies. Sorry I was out of Office and did not respond. I got past the stdext namespace errors. Can you please look at this post of mine. I can get the release versions working but not the debug.. I am pretty sure I have build debug versions of Boost with stlport. http://www.nabble.com/Link-errors-with-boost-regex-1_33_1%2C-Stlport-5.0-and... Mangal wrote:

Assuming you're certain that the regex lib was built with STLPort, try double checking that __STL_DEBUG is defined consistently between your app and the lib. Basically you need to ensure that regex and your app are built with identical options - and because STLPort introduces so many new possible build variants - that's why building regex from your IDE and manually checking that all the options are the same is often the path of least resistance. HTH, John.
Thanks John. This may not be the best place to post this question. When trying to build regex in the IDE( Visual studio 2005) the import library for the dll is not being created. I have checked in the IDE settings that import library name should be overriden to the name that I want. Any help is appreciated. Thanks John Maddock wrote:

That happens if no symbols are exported from the dll: make sure BOOST_REGEX_DYN_LINK is defined when building as a dll (and in the app that will be linking to it as well). BTW, unless you really need a dll (calling the regex lib from multiple dll's for example) you will get smaller code size from static linking. John.
