I guess fmax is not implemented; what alternative choices do I have; which one is better?
BTW, there are a few other math functions like nan, isnand, isinfd not defined.
Basically I try to port a Windows application to ARM Cortex M4 chip.
after I add math library (-lm), those errors are gone; however arm-none-eabi/bin/ld.exe complains "undefined reference to `__errno'".
There are a few errno.h under MCUXpresso IDE path. Which one shall I use?
Dear hedj@i2r.a-star.edu.sg,
You could also try to include the errno file the following way:
#include "errno.h"
The path should be automatically created when the project was created.
