Lots of errors when compiling from command line from sycl.hpp

[matthias11]

Dear all,

Operating system : Windows 10

OneAPI 2024.1

I'm trying to compile a simple vector addition example from command line. There are lots of error messages related to sycl.hpp. I don't know what is missing. Can you please help?

I'm using the command

icpx vector_add.cpp -o vector_add.exe

using icx instead is not really different.

Here are some of the error messages.

>icpx vector_add.cpp -o vector_add.exe

Hi @matthias11 

First, have you installed the oneAPI Base Toolkit and integrated it properly with the Visual Studio? 

Second, have you gotten a command prompt like something called "Intel oneAPI command prompt for Intel 64 for Visual Studio 2022?"

Third, can you try icx -fsycl vector_add.cpp -o vector_add.exe?

If it still fails, please show us what your vector_add.cpp is so we can do more investigation.

Hi Alex,

yes, I've done all of this. It compiles now. I had forgotten the -fsycl.

Many thanks and best wishes.
