Hi all, I'm trying to crosscompile xenomai 2.3.1 for the ppc-architecture. My commands are like this: (using latest denx ELDK)
export ARCH=ppc export CROSS_COMPILE=ppc_8xx- scripts/prepare-kernel.sh --arch=ppc --linux=/home/piie/toolchains/ppc-4.1/ppc_8xx/usr/src/linux/ --adeos=ksrc/arch/powerpc/patches/adeos-ipipe-2.6.18-ppc-1.5-01.patch cd bla/usr/src/linux/ make TQM8260_defconfig make menuconfig make uImage Everything is working so far and the kernel with built in xenomai boots flawless. (dmesg reports xenomai is working) When trying to crosscompile the xenomai libs and so on, the configure step is working correctly. ./configure -host=ppc-linux But the make fails because of missing headers: [..] error: asm/errno.h: No such file or directory [..] error: asm/param.h: No such file or directory [..] I took a look at the kernel/include/asm-ppc/ folder and actually these headers are missing. But they do exist for the "powerpc" architecture. So I just copied all missing headers from asm-powerpc/ to asm-ppc/ to try if the xenomai userspace things can be compiled. It worked. But I think that is not the way it has to be done. Does anybody know why these headers are missing in asm-ppc? Do I have to install some kind of BSP-kernel-patch for my specific board? Why are these headers available for powerpc? And btw, maybe someone of you knows, why are there 2 architectures for the powerpc architecture in the kernel tree? thanks for your help, --peter _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
