Well, I spoke too soon. I'm confident that avr-libc is built and installed
properly. But building avr-gcc (avr-toolchain) fails during the make -C a2
d phase:
...

./build.test: 58: Syntax error: "(" unexpected
Here's a synopsis of the steps I took previously:
1) download avr-libc-1.4.6.tar.bz2 from
http://download.savannah.gnu.org/releases/avr-libc/
2) download the avr-toolchain from Dave Hylands site:
http://www.davehylands.com/gumstix-wiki/avr-toolchain/
3) untar each into a separate directory
4) modify avr-toolchain build script as outlined in
http://docswiki.gumstix.com/Robostix_avr_gcc
5) Now, you can't build avr-libc first, since it relies on avr-gcc to build
.
So, I run ./build in avr-toolchain, which fails since avr-libc is not
installed!
6) Now build avr-libc:
./configure --build=`./config.guess` --host=avr --prefix=/home/paul/avr
make
su root
make install
(sudo make install failed because ~/avr/bin was not in the path)
7) Now build avr-toolchain, which results in the build failure listed above
.
Any advice on the overall sequence? What am I missing? Is the fact that
ldscripts/avr5.x is missing the culprit? If so, how can this be remedied?
Thanks
Paul
