I've just noticed that someone on CLFS ran 'make headers_check' and feared that the usual error reports (from kexec.h and soundcard.h) about "userspace cannot reference function or variable defined in the kernel" were errors.
In theory, running "make headers_check" allows _kernel_ devs to check that they aren't making things worse. In practice, these two messages have been present for as long as I can remember, without any userspace problems that are attributable to this, nor any interest in removing these two messages. So, although illustrating the command may have some use if we have any users who plan to be kernel devs, for a normal builder it appears to give zero utility. I suspect, as far as the book is concernd, that it is another of those ideas which seemed like a good idea at the time, but now serves no purpose. Should we just drop this command ? ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
