ICL EM64T problem: linking error on x64 targets

[servil]

Greetings,

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.

Which version of the Intel C++ compiler are you using?is it release config or debug? did you use /Qipo or /GL?

It could be a bug. But make sure to try the latest compiler update.

Thanks,
Jennifer

This is IntelC++ for EM64T, version 11.1

/Qipo wasnot used, release build

complete build options for xilink:

[JenniferJ]

could you post the link errors? and I'll check if there's an existing issue with it.

Also try to remove the options one by one to see which one caused the problem?

Thanks,
Jennifer

I have reproduced the same error with building PCRE C++ frontend library, x64

[JenniferJ]

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.

Quoting Jennifer Jiang (Intel)

1. does it happen without /Qipo? does it happen in /Od?

That's the solution. Now tried to decrease optimisation level, highest optimization level that links is O1.

Can optimizations be disabled partially like on MS compiler?

[JenniferJ]

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.

Thanks,
Jennifer
