RE: RTAI module install problem

Hi,

the problem is that depmod is for x86 and it can
therefore not handle PPC binaries. But the errors
should not harm. On the target you may need to install
the modules with "insmod" because module.dep is
not correct. Typically, on an embedded target you
link the drivers statically into the kernel.

Hope it helps,

Wolfgang.

Hi all.

I'll first tell you in short what I use.

Kernel: linuxppc_2_4_devel (from CVS on may 7th 2003)
RTAI Patch: ppc_devel_patch_2003_05_04_1125
Patch went perfect.

Cross-compiler: ELDK ppc_4xx
Target: EP405
Host: x86
INSTALL_MOD_PATH: /tmp/rmdisk_large

Config and vmlinux-compile don't give errors, RTAI is enabled.
Modules compile OK.
When installing the modules, I get this error:

cd /tmp/rmdisk_large/lib/modules/2.4.20-rthal5; \
mkdir -p pcmcia; \
find kernel -path '*/pcmcia/*' -name '*.o' | xargs -i -r ln -sf ../{}
pcmcia
if [ -r System.map ]; then /sbin/depmod -ae -F System.map -b
/tmp/rmdisk_large -r 2.4.20-rthal5; fi

make: *** [_modinst_post] Error 1

OK, this tells me that I'm using a somewhat wrong architecture (probably
wrong configured).
Does anybody know how I can solve this?

Thnx.
