Can Components from the Components Library be used in C++ projects?

In S32 DS we created a project for the mpc5748g and selected C++ as the programming language.

The project generates and compiles. But it is not possible to add components from the Component Explorer:

What needs to be done to use Components in a C++ project?

Hello,

unfortunately, this is not possible. SDK is determined for C projects only and cannot be used for C++ projects.

Martin

Hi Martin,

i just checked the S32_SDK_BETA_2.9.0. I found S32_SDK_BETA_2.9.0\platform\pal\ and a lot of drivers below. After checking some of them (can and i2c), these look like classic drivers, that is, drivers that do not require Device Expert code generation. If I do not miss something, these drivers can be used from C++, since it is no problem to call C code.

So you mean that Processor Expert and the Components Library integrated in S32 DS cannot be used in C++, only classic drivers from the SDK can be used?

Please clarify.

Hello,

in general, SDK code has never been tested in C++ projects and it is not determined to use in C++ project. I understand that C code can be called in C++ projects, but NXP cannot guarantee correct functionality.

So, you can try to use SDK drivers in your C++ project, but it is on your responsibility.

Martin

Hi Martin,

that means that C++ is currently NOT supported as an implementation language on the mpc5748g?

Is there a plan to support C++ in the future?

Regards,

Michael.

Hello Michael,

C++ project can be used in MPC5748G. I am only trying to explain that SDK drivers has never been tested in C++ projects.

So, you can write your own driver which is based on SDK driver using C++, but functionality of SDK driver is not guaranteed. From my point of view, it will work correct, but this is only my opinion.

Hope this helps.

Regards,

Martin
