[spirit,regex] Linking problems in VS 2008
I am using regex_p parser in Spirit. This uses Boost.Regex. The code
compiles fine but does not link. Error messages are (debug mode, static
linking, Boost 1.42):
--------------------
1>configuration.obj : error LNK2019: unresolved external symbol "public:
void __thiscall boost::re_detail::raw_storage::resize(unsigned int)"

The interesting thing is that if I turn language extensions on (/Za option) in the project the problem disappears. How can this be solved? Adam Badura

I believe this option changes ABI, therefore both your project and Boost.Regex must be build with the same value of this option. Does this help? - Volodya

How to do that (build Regex with /Za)? To build the library I used bjam. The command line is: -------------------- bjam --build-type=complete toolset=msvc-9.0 stage -------------------- Where to add /Za option? (Or any option in fact.) Adam Badura

Do you really need every single variant included in '--build-type=complete'?

Does http://www.boost.org/boost-build2/doc/html/bbv2/overview/invocation.html answer your question? It seems like cxxflags=/Za should work. You need to add -a to force full rebuild. - Volodya

I don't know. Maybe not. But HDD space is this days cheap unlike one's time so it seems simpler to build Boost once (every 3 months) entirely and then never to worry whether I have the needed binaries.

Yes. It did help. It is however a bit surprising as I think it should not help. I don't think /Za changes ABI. I still think that there is some other kind of error there but I am not as sure now. :) Another thing is that somehow less libraries where produced. But still it works now. Adam Badura
