Details:
This is my first post here, so if this is not the correct place to submit
this, I could use a little guidance. If this bug has already been reported,
please let me know.
In avr-libc 1.7.1, there appears to be an omission of the math.h file
include.
The /avr/include/util/delay.h.in file (which becomes delay.h in my installed
version) has calls to fabs() and ceil() with no declaration for these
functions, causing my compiler to throw those 2 errors.
I found the fix was to add the math.h include to
../avr/include/util/delay.h.in
At line 44, I added this
#include <math.h>
The fix can be applied after the install by adding the same line to the
/avr/include/util/delay.h file.
I attached both the delay.h.in file and the resulting delay.h file, both with
the bug fixes at line 44.
Thanks!
