Description bobf 2011-12-23 13:00:24 UTC
attempting to build code for avr using avr-gcc and avr-libc (arduino build environment).  Code that makes use of 'delay' causes several compile errors, similar to the following:

/usr/local/lib/gcc/avr/4.3.4/../../../../avr/include/util/delay.h:149: error: 'fabs' was not declared in this scope 

the problem and a workable solution are both described here

the attached patch file resolves this issue.

Fix: see attached patch file, that adds #include <math.h> to /usr/local/avr/include/util/delay.h

Patch attached with submission follows:
How-To-Repeat: install latest avr-libc and arduino build environment and attempt to build the 'blink' sample.
