Which C++ std compiler version used in TouchGFX Designer and MSVC simulator?

[BParh.1]

I have questions:

1. Which C++ std used when building code in TouchGFX Designer? c++11, c++14, c++17?
2. Which C++ std used when building code in MSVC simulator? c++11, c++14, c++17?
3. Which c++ std ST used to verify and release TouchGFX?
4. Can user change and modify the std? Any risk/ side effects to consider?

Did you ever find out which versions are supported?

My generated STM32Cube project uses C++14, but I would like to use C++17.

The project builds without errors using C++17.

Hello,

There's no standard library used in TouchGFX, but you can enable it in your Toolchain (STM32CubeIDE or Keil ...) project properties for your project's code.

Hi Louis,

Thanks, but the question was about which version of the C++ language (as standardised in ISO 14882) the TouchGFX code was written against.

It's unlikely to matter (as long as a "modern" version is used - C++14 and later), but there are some subtle changes in behaviour that may get in the way if they are not considered.

Hello @CTapp.1 ,

Concerning the version of C++, TouchGFX only uses C++98 language features. Therefore, compiling the project using newer language versions should be safe. 

I hope that answers your question.

Unfortunately I can't, as I didn't start this topic 😉

No problem :), I'll mark it as best answer.
