I'm trying to figure out where _SFR_IO_ADDR is defined.  I've installed v0007 of the arduino software on my FC5 linux box and (I think ) all the necessary libraries.  The Java app runs fine, but when compiling any source I get:

   warning: implicit declaration of function `_SFR_IO_ADDR'

from the 'lib/targets/arduino/pins_arduino.c' file.   This is then followed by about 9 errors on the following lines that try to use this macro.  I've got this installed:

 # rpm -qa | grep cdk

Am I missing anything?  Thanks!


It should be defined in avr/sfr_defs.h, which should be included by avr/io.h.  Does the "base" package you have installed include avr-libc?


Hi, thanks for the quick response!  It doesn't look like the base package contains avr-libc.  Apparently I missed that package when downloading.  Finding and installing that also led me to discover that my RPM situation was a mess; I had AVR RPM packages installed from two different sources, both providing the same files, but in (sometimes) different places.

I uninstalled everything and reinstalled only the cdk-* RPMs and my environment works like a charm now.  Thanks!
