Hi All,
Attached are patches for binutils, gcc, avr-libc for ATmega128 support.
These are for gcc-3.0.4, binutils-2.11.2 and avr-libc
20020203.
to use these get the binutils 2.11.2 and gcc 3.0.4 source package,
untar the sources,apply the patches, configure the packages, make the
package and install them.
eg. (this puts the build files in a different directory)
tar xvzf binutils-2.11.2
cd binutils-2.11.2
patch -p1 < binutils-2.11.2-patch128
cd ..
mkdir build-binutils
cd build-binutils
../binutils-2.11.2/configure --target=avr
(lots of output)
make
(lots of output)
make install (as root)
(lots more output)
tar xvzf gcc-3.0.4
cd gcc-3.0.4
patch -p1 < gcc-3.0.4-patch128
cd ..
mkdir build-gcc
cd build-gcc
../gcc/configure --target=avr --enable-languages=c
(lots of output)
make
(lots of output)
make install (as root)
(lots more output)
you may want avr-libc also configure and make this as per its
instructions.
Thanks to Theodore A. Roth <address@hidden> for helping check some of
these patches.
