[Boost-users] Re: [regex] Unresolved external symbols under VC7.1w/dynamic linking

OK, that's the problem: BOOST_DYN_LINK is an internal Boost macro [snip] You should be defining one of:

BOOST_ALL_DYN_LINK: make all Boost libs link as dll's. BOOST_REGEX_DYN_LINK: make regex only link as a dll.

D'oh! Thank you.

Be careful not to mix /MD with /D_DEBUG, it confuses the auto-link code (not really a Boost issue, it affects any libray that's linked with #pragma comment).

Yes, I was assuming a release build.

HTH,

It did, thanks.

John.
