ICC XE 13.0 fails to recompile only changed files on "build" command in MSVC

[Marián__VooDooMan__M]

My environment:

MSVC 2010
ICC XE 13.0
Quad core Intel CPU
using compile flags "/MP" and "/Gm".

when link phase dies because *.pdb file is in use, so it could not be overwritten, I close this file, and hit "F5" to try again. ICC is not honoring "/Gm" flag, instead, it re-compiles whole (rather big) project, over again, which lasts for another wasteful 10 minutes of waiting, though, only link is required.

The issue is still there, when I make a change to single .cpp unit, it re-compiles the whole solution.

This issue is easily to reproduce, so I will not post the test case.

I should mention I am using PCH.

It is rebuilding all .cpp units, which is odd... some .cpp (and their include headers) doesn't change, but it is recompiling.

We encounter the same problem. We use Visual Studio 2012. Our projects always does a full rebuild when changing only one file. When I switch back the project to use the Visual Studio 2012 compiler, everything works fine. Switching to the Intel Compiler always results in a full rebuild, no matter what and where I apply changes. Environment: WIN7x64 ULTIMATE MSVC 2012 ICC XE 13.0 Hexa core Intel CPU using compile flags "/MP" but no precompiled headers. Is this a known issue or any hints on how to correct this?

Greetings, Jennifer, I thank as well as this bug was annoying (and time-consuming for large projects). EDIT: @"th - IPACS Developer": Though I am on MSVC 2010 Ultimate (x64 project) @ Vista Ultimate x64

Hello Jennifer, I can confirm the issue is resolved/fixed in the latest (non-beta) ICC 13.0 . Even if I am using /MP switch in MSVC 2010.
