fenv - undefined reference to `FSLieee_status'

Hi everybody,

I try to use standard C99 fesetround function to change Cortex-M4F (S32K144) rounding mode.

Unfortunately, the linker return the following errors :

S32DS/arm_ewl2/EWL_C/src/arm/fenv_arm.c:234: undefined reference to `__FSL__ieee_status' S32DS/arm_ewl2/EWL_C/src/arm/fenv_arm.c:235: undefined reference to `__FSL__ieee_status'

Did anyone see that already ?

My project is configured to use C99 standard in Properties->C/C++Build->Settings->Standard S32DS C Compiler->Dialect

I use s32DS 2018.R1.

Thanks by advance !

Hi,

sorry for delay.I went through the EWL C library, and the library is compiled in way, that _FSL_ieee_status (and other HW float point stuff) is implemented by user application.
