Re: [Boost-users] Boost.Regex - why does it core dump?

I just reproduced it again. Here's the setup:

$(WIN32_TARGET): export STLPORT_PATH=../STLport-4.6.2/ ;\ export MSVCDir=$VCINSTALLDIR ;\ ./configure --with-toolset=vc-7_1-stlport --with-bjam=tools/build/jam_src/bin.ntx86/bjam.exe ;\ tools/build/jam_src/bin.ntx86/bjam.exe "-sTOOLS=vc-7_1-stlport" --with-regex stage

Then at link time, the application catches:

unresolved external symbol "void __cdecl boost::re_detail::raise_runtime_error(class _STL::runtime_error const &)"...

unresolved external symbol "class _STL::basic_string __cdecl boost::re_detail::w32_transform(unsigned long,char const *,char const *)"...

So I copy and paste those into my application's cpp file, and they link. Then I crash here:

Linker errors are there to tell you something: the lib file you're linking against is *not* binary compatible with your applications build options. So.... are you letting autolink pick the right lib to link against or have you over-riden an error there as well? Are you defining __STL_DEBUG in debug builds? The bjam built libs do so, and you'll need to define __STL_DEBUG to link against them. The autolink code should have picked this one up however. If all esle fails I suggest you build the regex lib from the IDE with *exactly* the same options as your application: remember it's just a bunch of sources, you can add the source code directly to your project as well if you want (define BOOST_REGEX_NO_LIB to disable autolinking if you do so however). Hopefully that will clear the problem's you're seeing. John.
