for some projects linking fails with error of unresolved external. Having demangle reported names I've deduced those are unwind chunks of own function(s). Have observed only with Intel64 code, link succeeded for x86 platform of the same code. Any resolution, or is this a known problem? Eventually, I'll appreciate any solutions to overcome this error.
I remember we've fixed a similar issue with such unresolved symbol before, but I didn't find the case number.
Several things to try: 1. does it happen without /Qipo? does it happen in /Od? 2. try to build from the build-environment from "Start -> All programs ->....". (not sure which IntelC version you're using, the menu is different), then add additional include/path/lib directories.
Yes, you can lower the optimization at file-level.
But I've seen such bug before and is fixed. so try to log-on to the Intel Registration Center to download the latest update. For 11.1, the update 8 just released this week. For 12.0 (Composer XE) the update1 is released last week or the week before.
