| |
vmlinux-deps is unneeded because the dependency can directly list $(KBUILD_LDS) $(KBUILD_VMLINUX_OBJS) $(KBUILD_VMLINUX_LIBS)
Do not cancel the rule; building an individual vmlinux.lds, built-in.a, or lib.a is working now, but the warning "overriding recipe for target" is shown.
Without this patch:
$ make arch/x86/kernel/vmlinux.lds Makefile:1798: warning: overriding recipe for target 'arch/x86/kernel/vmlinux.lds' Makefile:1162: warning: ignoring old recipe for target 'arch/x86/kernel/vmlinux.lds' [ snip ] LDS arch/x86/kernel/vmlinux.lds
