[Interest] Building Qt5 with Intel C++ under Windows

[Saether Jan-Arve]

Sorry for top posting. I only have OWA access here...

Yeah, likely a missing include, which root cause can be that icc is not fully MSVC compliant. 
Since the files are generated by MIDL tool it seems to assume that a compiler from the same toolchain willl be used to compile the generated files, thus it might generate code with non-standard constructs. 

If ICC can link with MSVC object files, a possibly (ugly) workaround is to compile the iaccessible2 files with MSVC. You would have to create an EXTRA_COMPILER (IIRC) where you use cl.exe for the iaccessible2 files (passing the same compiler flags of course).

I'm not an expert on this myself (even though I added these), but I've lately realized that some of these files can possibly be removed. Some of the other generated files cause headaches in other situations, too (e.g. static builds).

Correct. It's supported by me, on a best-effort basis (tier 2 style). That
means the actual Qt release may fail until I get a chance to try it and fix the
issues.

In fact, I'm more reactive: if you have a problem and report it, I'll try fix
it. So if you report it during the beta or release candidate period, I'll
probably have enough time before the release.

Right.

It's a missing #include, it has to be.
