I spent a bit of time around FOSDEM trying to build an armel toolchain
from current sources and Lennerts patches.
It's not working and I'm a bit perplexed. Clues welcome.
What I did:
Used the updated dpkg and dpkg-cross as has been discussed in other
mails, to
a) build and install cross binutils (v 2.17-3) - no probs.
<patched binutils>
TARGET=armel fakeroot debian/rules binary-cross
dpkg -i binutils-arm-linux-gnueabi_2.17-3_i386.deb
b) install cross linux-kernel-headers_2.6.18-6 glibc6 glibc6-dev (with
dpkg-cross/apt-cross) from Lennert's ADS repository.
This required a bit of hand-tending, because apt-cross 'download, cross and
install'
and dpkg-cross 'build and install in one go' gave me whinges (I haven't
investigated quite why).
so the manual version is:
wget <armel package tzdata, libc6, libc6-dev>
dpkg-cross -aarmel -b linux-kernel-headers_2.6.18-6_all.deb
dpkg-cross -aarmel -b libc6_2.5-0exp3_armel.deb
dpkg-cross -aarmel -b libc6-dev_2.5-0exp3_armel.deb
dpkg-cross -aarmel -b -A tzdata_2006p-1_all.deb
dpkg -i linux-kernel-headers-armel-cross_2.6.18-6_all.deb
dpkg -i tzdata-armel-cross_2006p-1_all.deb
dpkg -i libc6-armel-cross_2.5-0exp3_all.deb
dpkg -i libc6-dev-armel-cross_2.5-0exp3_all.deb
c) build gcc (gcc-4.1-4.1.1ds2) with:
(current source already has armel patches in, but I did modify them to fix up
some
stuff in rules2 where armeb/armel was used a a CPU name, as mentioned in a
previous mail)
echo armel > debian/target
DEB_CROSS_INDEPENDENT=yes dpkg-buildpackage -us -uc -B -rfakeroot
which goes OK building a load of stuff until it tries to link with glibc, when
we get:
/usr/arm-linux-gnueabi/lib/libc.so.6: file not recognized: File format not
recognized
What's that about? Is that actual binutils not working right?
here is the end of the gcc build log in case it helps.
