I am trying to cross-compile NTP for the Raspberry Pi, and I am
following the instructions for NTP here:
http://support.ntp.org/bin/view/Dev/Cross-compilingNTP
and the successful cross-compile I did for the RPi kernel here:
http://www.satsignal.eu/raspberry-pi/kernel-cross-compile.html
Just following the "NTP" instructions, although I did end up with
executables, they did not run on the RPi (giving an error something like
"binary format error"), and their size is very similar to the
executables for the Intel Debian system on which I was cross compiling.
So it seems to me that I have not cross-compiled but natively compiled.
With the RPi kernel compile, I needed to create a couple of environment
variables:
CCPREFIX
PLATFORM
and run a make/compile command like:
make ARCH=arm CROSS_COMPILE=${CCPREFIX}
whereas the NTP instructions suggest using just a "make" command. I
also see differences in the make/install command between the two sets on
instructions:
NTP:
make DESTDIR=`pwd`/:Built install
RPi:
MODULES_TEMP=~/modules
export MODULES_TEMP
make ARCH=arm CROSS_COMPILE=${CCPREFIX}
INSTALL_MOD_PATH=${MODULES_TEMP} modules_install
Now this could be due to the RPi command being for a Kernel compile, and
the NTP one being for a set of executables. Perhaps there is no problem
here.
I am working right at the limit of my knowledge here, so any help in
using the right compiler would be most welcome!
