Unable to use round function

DemaQasem — Sun, 04 Feb 2024 11:06:36 GMT

Hello,

I am implementing a project on S32K144 using the S32DS IDE v3.4, when I use the "round" function and build the project I get the error :

even though I made sure to include the math.h library
any reason for that ?

Thank you.

Hi,

math.h is only header file for math library. You need to add libm.a library into your project in project properties:

Is there a similar solution for the imxrt1176

I am getting a similar error this is the embedded coder window

The exact error from the diagnostic window

Hi,

I'm not familiar with imxrt1176 and it's development tool, but the principle is very same. You need add math library and let the linker know where the library archive is (library path - if it is not already configured).
