Maybe your header files are in /usr/src/linux/include ?

the ones installed by sys-kernel/linux26-headers are in /usr/include/linux.
BTW can someone explain me why this package exist? It's not enaugh the 
linux ones, the only answer I can give myself is not to be constricted 
to recompile a bunch of programs every time u change kernel. It's the 
right answer ?

Or maybe you're using KERNEL_OUTPUT? In that case vmware modules
compilation fails badly before it has started. You can get my patched
ebuilds from my personal portage overlay at
rsync://rsync.gg3.net/gentoo-portage-chutz/app-emulation/vmware-workstation/.
These cut out large portions of vmware-config.pl that do nothing but ask
silly questions (like "where are your headers", since it is gentoo policy
that /usr/src/linux should point to your current kernel) and also patch
the appropriate makefiles.

glibc compiles against the headers in /usr/include/linux.
Programs that link against glibc (read: all programs) need to include the
headers that glibc was built against in order to link properly. These
headers need to always correspond to the version that glibc was compiled
against. Hence the warnings that the linux-headers ebuild spits out at
installation, reminding you to recompile glibc next.

mmmh I belive you but in this case why not keep gentoo-dev-sources and 
linux26-headers and avoid download of two kernel sources, or ask at the 
installer which kernel he/she want to run ?

Because programs may break against the latest headers. I had problems when
I first tried linux26-headers on my system, because iptables for example
failed to compile. Considering how often external kernel modules fail
because of changes to the kernel structures, it is understandable that the
version of the headers you use to compile your userland applications has
to be a tested one, and not necessarily related to the version of the
kernel you are running.

I posted that question on 9 Nov, since then I've updated my kernel at least 
twice.  And the problem has been corrected.  I don't know people are just now 
sending replies to this thread.

So ... which do we use? /usr/src/linux? usr/include/linux?
/lib/modules/2.6.9-gentoo-r3/build/include?

Because there were no replies.
And because I have problems getting vmWare to run, so I'm searching
for messages regarding vmWare. And yours showed up...

To answer my own question, and to restate what Georgi wrote
(sorry for stripping your name from the quote):
/usr/src/linux contains (or should contain) the default (or latest)
kernel so /usr/src/linux/include contains that kernels headers.
/usr/src/linux-2.6.9-gentoo-r3/include would then contain the
headers for that specific version of the kernel.

/lib/modues/2.6.9-gentoo-r3/build/include contains the kernel
headers used for compiling that version of the modules.

/usr/include/linux contains the C-library headers (ie. for printf
and atoi and so on).

Matthew Marlowe suggested the any-any-84 patch from http://ftp.cvut.cz/vmware/.
That did wonders. Thanks!

Just upgrade your kernel.  That did the trick for me. But with 
gentoo-dev-sources, it seems to be impossible as they have new versions every 
other day it seems. <grin>

Not exactly. "printf" is defined in /usr/include/stdio.h, "atoi" is
defined in /usr/include/stdlib.h.

You gave examples with basic functions that have nothing to do with
the kernel. There is a nice quote in the LFS book:

http://lfs.osuosl.org/lfs/view/5.1.1/chapter06/kernelheaders.html

As it states:

 The essential part is where Linus states that the header files should be
 the ones which Glibc was compiled against. These are the headers that
 should be used when you later compile other packages, as they are the
 ones that match the object-code library files. By copying the headers
 [to /usr/include/linux], we ensure that they remain available if later
 you upgrade your kernel.

So, if you use the headers for 2.6.9 and you run a 2.6.9 kernel, the
headers in /usr/include/linux and /usr/src/linux/include/linux will be
identical.
