First of all, thank you for your reply.
When I create a new project, this error occurs if I select IAR's cross-compile tool, and if I export this project to the IAR compiler, this error is converted into a warning.
If I had chosen other cross-compilation tools, this problem would not have arisen, and I suspect that the same should be true for instance projects. As for why this problem arises, I still need some time to figure it out.
Finally, I would like to ask you again. If I don't choose IAR's cross-compile tool, will it make any difference when I port my project to the IAR compiler?
Thank you
