Hi,

i try to build a valid toolchain for nanonote ben. i cannot get a valid toolchain/binarys. Its the second time i make it (openmoko with tutorial) so please be thoughtful.
device: http://en.qi-hardware.com/wiki/Ben_NanoNote

file on nano bin: ELF 32-bit LSB executable, MIPS, MIPS32 version 1, dynamically linked (uses shared libs), corrupted section header size
file on my bin: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 (SYSV), dynamically linked (uses shared libs), with unknown capability 0xf41 = 0x756e6700, stripped


I think it is because of SYSV.

Have you tried linking your test app statically?

no, but uclibc was installed. i just compile it again with static

THX! busybox works now and i think i just have to install baselayout for bash.... after this works i need a kernel. sadly it is embedded into the toolchain/buildenv of openwrt http://en.qi-hardware.com/wiki/Building_Software_Image

will continute reporting here and in future in gentoo-wiki or qi-hardware.

root@BenNanoNote:/mnt# chroot .
@BenNanoNote:/# bash
bash: /dev/null: No such file or directory
BenNanoNote / # qfile /dev
bash: qfile: command not found
BenNanoNote / #

edit 01:13 cest
portage; kernel
but python is tricky like ncurses with cxx

<shameless plug>

I have a snapshot of a softfloat MIPS32 gentoo installation here:
http://mlau.at/files/mips32-linux/

Only difference is that it's based on glibc, not uclibc. But it contains
everything you need to compile stuff.
