Re: [Boost-users] Regex boost 1.33 - (mingw/w32) linking

Thanks John, for your time and quick answers. I found the issue: I compiled "grep.cpp" with -O3 and this leads to: - error at linking on debug version of the library (libboost_regex-mgw-mt-d-1_33.lib) - OK linking with non-debug version (libboost_regex-mgw-mt-1_33.lib)

I am quite unfamiliar with g++ (and it is quite off topic here) but seems strange to me that an optimization level ruins a linking...

I'm glad we got to the bottom of that, I agree that's strange, and I'm not a gcc expert either, so <shrug> I guess, John.
