VS2017 / ComputeCpp:RT0100 Binary format for key=‘0’, ident=’’ is not recognized```

SYCL development
1

When compiling with the VS2017 integration, adding the -sycl-target ptx64 option to

main.cpp ->Properties->Configuration Properties -> ComputeCpp SYCL Cpp->Device->Additional Options: -sycl-target ptx64

and running code on nVIDIA I get this error:

error : Binary format for key=‘0’, ident=’’ is not recognized

This is caused by the -emit-llvm options being passed to Computecpp. (Thanks to morris hafner for spotting this)

I’ve track this down to:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\BuildCustomizations\ComputeCpp.props

and

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\BuildCustomizations\ComputeCpp.props

Where on line 106 () that -emit-llvm option can be removed.

Note: it looks like this problem is specific to the (so far unsupported) scenario of producing PTX code for nVIDIA on visual studio.

Thanks Jan. We’re raising an issue internally to deal with that.

Hi Jan, we were able to fix this in the template files so it has been updated and is in the v1.1.1 release now available on our website. So you can simply include the -sycl-target in “Additional Options”
