Crosscompiling a kernel, the Debian way
First, you'll have to make sure that you have installed the appropriate packages:
<![CDATA[# dpkg --get-selections | grep sparc
binutils-sparc install
cpp-2.95-sparc install
g++-2.95-sparc install
gcc-2.95-sparc install
libc6-dev-sparc-cross install
libc6-sparc-cross install
libstdc++2.10-dev-sparc install
libstdc++2.10-glibc2.2-sparc install
# dpkg --get-selections | grep kernel-package
kernel-package install]]>
Next, setup the kernel source:
<![CDATA[# wget -O- ftp://ftp.snt.utwente.nl/pub/os/linux/kernel/v2.4/linux-2.4.23.tar.bz2 | tar jx
# cd linux-2.4.23
# make ARCH=sparc menuconfig]]>
Next, we build the kernel package:
<![CDATA[# fakeroot make-kpkg --arch=sparc --cross-compile=sparc-linux --rev jdp.1 binary
dpkg-architecture: warning: Specified GNU system type sparc-linux does not match gcc system type i386-linux.
dpkg-architecture: warning: Specified GNU system type sparc-linux does not match gcc system type i386-linux.
dpkg-architecture: warning: Specified GNU system type sparc-linux does not match gcc system type i386-linux.
...]]>
You will see it complains that it's cross-compiling, don't worry about that.
Speeding things up
kernel-package is capable of parallel builds, using the
make -j command. It is suggested you use a concurrency of nCPU + 1.
place a file in your homedir:
~/.kernel-pkg.conf:
<![CDATA[maintainer := Your name
email := name@somedomain.com
priority := Low
CONCURRENCY_LEVEL := 2]]>
