How should the symbolic links be setup to compile the latest kernel?


Currently I had these links and kernels compiled fine until 2 days ago.

asm -> /usr/src/linux/include/uapi/asm-generic/
asm-generic -> /usr/src/linux/include/uapi/asm-generic
linux -> /usr/src/linux/include/uapi/linux


# make
make[1]: Nothing to be done for `all'.
HOSTCC arch/x86/tools/relocs
In file included from /usr/include/bits/errno.h:24:0,

from arch/x86/tools/relocs.c:6:

file or directory
compilation terminated.
make[1]: *** [arch/x86/tools/relocs] Error 1

Thanks,
Jeff

What symlinks? /usr/include/* should not contain any symlinks into
the kernel source. At all.

Al,

Oh, perhaps I'm having the right setup. Where should I get the kernel
headers. After removing the links to the kernel source, here what I
got ...

make[1]: Nothing to be done for `all'.
HOSTCC scripts/basic/fixdep
In file included from /usr/include/bits/posix1_lim.h:160:0,
from /usr/include/limits.h:144,
from scripts/basic/fixdep.c:114:
/usr/include/bits/local_lim.h:38:26: fatal error: linux/limits.h: No
such file or directory
compilation terminated.

Thanks,
Jeff.

NOT having the right setup.

From your libc. Which ought to have its own copies, normally coming from
make headers_install in kernel source. And yes, it had been that way
for many years by now. Userland should *not* blindly grab the kernel
headers.

Incidentally, your 'asm' is obviously bogus - the headers that should end
up there ought to come from arch/<whatever>/include/uapi/asm (and _not_
by pointing a symlink to it); yours points to the place where asm-generic
ones ought to have been copied from.

Al,

Thanks for the pointers. Will try as what you suggested:)

Merry Christmas.
