Hi
Compiling ppc fails for me with 2.6.19 kernels.
( I compile on a Pegasos PPC 601 Debian Linux).
If I use ARCH=ppc then I get the following error:
CHK include/linux/version.h
CHK include/linux/utsrelease.h
CHK include/linux/compile.h
gcc: include/asm/byteorder.h: No such file or directory
Hmm, strange.
gcc: no input files
CC arch/ppc/xenomai/hal.o
arch/ppc/xenomai/hal.c: In function 'rthal_arch_init':
arch/ppc/xenomai/hal.c:353: error: invalid type argument of '->'
make[1]: *** [arch/ppc/xenomai/hal.o] Fehler 1
That looks like an altivec problem. Does the attached patch for Xenomai
help?
Trying to use ARCH=powerpc fails already while configuring the kernel
like this:
make ARCH=powerpc menuconfig
HOSTCC scripts/kconfig/mconf.o
HOSTLD scripts/kconfig/mconf
scripts/kconfig/mconf arch/powerpc/Kconfig
init/Kconfig:564:warning: 'select' used by config symbol 'XENOMAI' refer to
undefined symbol 'IPIPE' #
# configuration written to .config
#
And a make gives me
make ARCH=powerpc menuconfig
HOSTCC scripts/kconfig/mconf.o
HOSTLD scripts/kconfig/mconf
scripts/kconfig/mconf arch/powerpc/Kconfig
init/Kconfig:564:warning: 'select' used by config symbol 'XENOMAI' refer to
undefined symbol 'IPIPE' #
# configuration written to .config
#
The powerpc tree is not yet supported.
What is wrong? Did I miss something in my setup? Wrong config?
Seems to be an untested configuration!?
