Re: [Boost-users] regex: link issue on Visual Studio 11 (v17) x64

Hey there, I've just built Boost 1.49 with Visual Studio 11 (cl.exe v17) and that worked (bjam knows about the compiler version already). I do get a linking issue though when using regex in a debug/x64 (static boost, static run-time) build:

unresolved external symbol "private: class boost::basic_regex

The issue surfaces when calling boost::regex_match() with a boost::wregex expression.

Here are some debugging notes:

a.. This same application linked against Boost 1.48 using Visual Studio 2010 (cl.exe v16). This build did not have ICU.

b.. I have just built ICU and fed it too bjam's command line (-sICU_PATH=....), both 32- and 64-bit versions were detected, regex was built. Yet it made no difference to the final link step.

It seems the issue is not related to ICU... I am guessing regex speaks unicode using a specific Windows backend, but I am lost here. Could someone help debugging this please?

Not much as I don't have VS11. Things to check: * Are the libraries really 64 bit ones, or were 32 bit ones built by mistake? * Does a hello world app that uses boost::regex work? * Take a peek inside the libraries and see what symbols are defined - there should be both wchar_t and unsigned short versions in there. If all else fails and you just want to move on - define BOOST_REGEX_NO_LIB in your project, and build Boost.Regex as a dll or static lib project in your IDE - it's "just a bunch of source files" in libs/regex/src, nothing special about building it. HTH, John.
