Kernel cross compilation

From Alpha Linux Wiki

The steps below works for cross compiling a kernel.

Since there's no port of the libs and include files it most likely won't work for anything but kernels.

The host is an AMD Athlon 64 3 GHz running Slackware 13.0.

The target my AlphaStation 255, EV45 300 MHz running Debian 5.0.

Binutils

tar -xvjf /mnt/tmp/binutils-2.20.tar.bz2 
cd binutils-2.20/
./configure --target=alphaev45-unknown-linux-gnu --prefix=/usr/cross –disable-nls
make
make install

GCC

tar -xvjf /mnt/tmp/gcc-4.3.4.tar.bz2 
cd gcc-4.3.4/
./configure --prefix=/usr/cross/ --target=alphaev45-unknown-linux-gnu \
--disable-nls --without-headers –enable-languages=c,c++
make all-gcc
make install-gcc

The Kernel

tar -xvjf linux-2.6.33-rc5.tar.bz2
cd linux-2.6.33-rc5.tar.bz2/
export ARCH=alpha
make menuconfig
export PATH=$PATH:/usr/cross/bin
export CROSS_COMPILE=alphaev45-unknown-linux-gnu-
make
