icl error with msbuild

After installing IntelV16 Update1 and VS2015 Update 1 , my buildprocess is broken when msbuild(14.0.24720) is used .

icl complains "icl: : error : option '/Qopt-matmul' not supported", if "Enable Matrix Multiply Library Call" is set to any other value than "Default".

Building from inside VS or with devenv is not affected.

I have attached a simple testcase for reproducing.

Bug or Feature ?

(background the real application has 287 projectfiles , and I don't want change every project by hand, as workaround I build now with devenv)

Kind Regards

Steffen

As /Qopt-matmul pertains only to Fortran, it seems a bug if any setting in a C or C++ project causes that option to be passed to ICL.  Maybe that's your point.

I didn't see any remarks in the compiler documentation , that this flag is only for Fortran .

And on the other hand with devenv it works, also I have compared the output from msbuild (diagnostic level) started from inside Visual Studio and the commandline , and they looks identical for me . Anything I'm missed ....

Ok , now I'm a step further .

Not /Qopt-matmul is the problem , /Qparallel is not recognized , when it is set through the properties . If I add this to the additional option on the commandline , the problem doesn't occur longer . The same thing affects also some other options (/Qopenmp,/Qstd=c++11 as example)

Hello,

Thanks for reporting this.  It's reproducible.  msbuild doesn't see that /Qparallel is set, and that causes /Qopt-matmul to fail:

ClCompile:

/Qopt-matmul is supported, but requires /Qparallel to be set.  The error message is misleading.

I'll report this to the developers.
