All asm-*/offsets.h files have been deleted from the base tarball, they are generated files. make -f arch/ia64/tools/Makefile /build/kaos/2.5.44-ia64-021024/include/asm-ia64/offsets.h /usr/bin/ia64-linux-gcc -g -O2 -Wall -D__KERNEL__ -Iinclude -DKBUILD_BASENAME=print_offsets_ -S arch/ia64/tools/print_offsets.c -o arch/ia64/tools/print_offsets.s In file included from include/linux/thread_info.h:11, from include/linux/spinlock.h:12, from include/linux/capability.h:44, from include/linux/sched.h:9, from arch/ia64/tools/print_offsets.c:17: include/asm/thread_info.h:8:25: asm/offsets.h: No such file or directory include/asm/ptrace.h:56:25: asm/offsets.h: No such file or directory include/asm/processor.h:87:25: asm/offsets.h: No such file or directory Worse than that, not only does the code to calculate offsets.h need to read offsets.h, it also needs the value of IA64_TASK_SIZE from offsets.h so it can build offsets.h, an empty offsets.h will not do. Quick and dirty workaround while I convert arch/ia64/makefile to generate offsets.h using the standard method and remove this recursive dependency (and get kdb for ia64 2.5.44 working).
