QtCreator with Intel OneAPI SYCL

Question

I started my study with OneAPI SYCL but I normally use QtCreator as my IDE. I did a HelloSYCL project with CMake and works fine in the terminal and in the VSCode with OneAPI Extension as well, but didn't work in the QtCreator.

Every time I want to use SYCL I need to start ONEAPI environment with ". /opt/intel/oneapi/setvars.sh", but I don't know how to do it with QtCreator

Here is the way I'm compile

mkdir build; cd build
cmake -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx -G Ninja -S .. -DCMAKE_PREFIX_PATH="/opt/intel/oneapi/compiler/latest/linux/cmake/SYCL/" -DSYCL_INCLUDE_DIR=/opt/intel/oneapi/compiler/latest/linux/include/sycl -DSYCL_LIBRARY_DIR=/opt/intel/oneapi/compiler/latest/linux/lib

QtCreator CMake Error QtCreator Custom Compiler added

Answer 1

The answer depends on the contents of setvars.sh. I assume this is a simple script setting environment variables.

One way to mimic it in QtCreator is to define a custom kit. Go to Tools/Options/Kits. Highlight any kit you use and press "clone". Then, add to it manually the necessary environment variables in the field "Environment". Use this kit for your SYCL projects. This will work if your problem is caused by a compiler error.

If the problem occurs while running a program inside QtCreator, look at build/running options:

There you'll easily find options for changing the runtime or compile-time environment
