fesetround? fenv.h not found

JBM — Fri, 01 May 2020 13:46:23 GMT

I'm running KDS 3.2.0, arm-none-eabi-gcc.exe version 4.8.4, language standard ISO C99. Processor is the K22FN512VLH12.

I'm trying to use fesetround that should be in fenv.h, but the compiler is tell me that fenv.h is not found.

Is fesetround supported?

Thanks.

Hi James Millard ,

KDS is the old IDE, which is not updated now.

Now, we mainly use the MCUXpresso IDE, which is used to replace the KDS.

You can download it from this link: www.nxp.com/mcuxpresso

I have checked, this IDE contains the fenv.h.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Kerry

Thanks, that's what I was afraid of. Didn't really want to migrate this project, but oh well.

That's under the C++ headers. What about C? Using MCUXpresso and any of the C standards, I still get include file not found. Those same C++ headers are available in KDS too.

Hi James Millard

I search it, and didn't find the C code in the MCUXPresso IDE.

Maybe you can find the related files in the website, and add it in your code.
