Cross compiling is dead easy, if you are a Debian user (*always* use
'lenny' for emdebian, even if you are locally using 'squeeze' or 'sid'):
----
# cat <<EOF > /etc/apt/sources.list.d/emdebian.list
deb http://www.emdebian.org/debian/ lenny main
EOF
# aptitude update
# aptitude install gcc-4.3-arm-linux-gnueabi libc6-dev-armel-cross
----
Then when cross compiling you can use the shell alias:
----
alias amake="ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make"
----
Then inside the Linux kernel directory just type 'amake menuconfig;
amake'...much faster.
If you are not using Debian (why not? :) then you can use buildroot if
your distro does not come with cross-compiling tools. On my website I
have a page describing the process for a MIPS platform, if you need any
help do ask:
