I am trying to build the avr tool chain in osx 10.2.6, but I am having
difficulty compiling gcc.
For the most part, I am following the instructions listed in the
avr-libc manual..
http://savannah.nongnu.org/download/avr-libc/doc/avr-libc-user-manual/
install_tools.html
I downloaded the source tarballs from the links at the top of
http://savannah.nongnu.org/download/avr-libc/released/
binutils-2.14 with the info fix patch applied
gcc-core-3.3.1 with the combine and info fix patches applied
I built and installed binutils 2.14 using /usr/local/avr as my prefix
dir. I have /usr/local/avr/bin and sbin in my PATH.
When compiling gcc, I get a few errors, and I'm not sure what to do
about them. I looked at builtin-attrs.def, but was unable to figure
out why gcc complains about a missing right curly brace. Below is the
output of make, minus a _lot_ of "warning: style of line directive is
a GCC extension" (not noted) and a handful of very similar errors
(-cut-). If the entire output would help to figure out the problem,
let me know.
Thanks,
John
