2.5.19 : 'make dep' error

[Frank Davis]

Hello all,
  I received the following error for 'make dep' . 2.5.18 works fine. 'make 
mrproper' was done after patching from 2.5.18. 
Regards,
Frank

Uh-oh, your system doesn't build user space applications (that's not even 
kernel specific). I suppose you have a symlink from /usr/include/asm
to /usr/src/linux/include/asm? Ask google why that is not a good idea - 
well, actually, you have the answer right there ;-)

The kernel asm-i386/errno.h was changed to just include
asm-generic/errno.h in 2.5.19. Unfortunately, due to the symlink, your
userspace includes the kernel asm/errno.h, which now points to the (for 
userspace non existing) asm-generic/errno.h - bad luck.

So fix your setup to not use symlinks, or, at least, put an older kernel 
back into /usr/src/linux and compile the new kernels elsewhere.

Or use the following:

+++ linux/scripts/Makefile	Wed May 29 21:46:58 2002

I find it perfectly idiotic to tell people to use older kernel
include. Better to tell them to use stable versions if they do
not know what they do.

I want applications to be build with the new kernel headers,
including new API, especially when some aren't backward
compatible, and I think I'm not alone. And the only way to find
these is to symlink those headers to the utilised kernel release.

Well, are you sure you know what you're doing? This may get you through
the kernel build (though I suspect you have to do the same for mkdep), but
basically not a single user space application will compile on your
bleeding edge box from now on...
