[U-Boot-Users] U-Boot V2: error: unable to open 'stdarg.h'

[Nishanth Menon]

Hi Folks,

Been stumped with the sandbox a bit on getting sparse to check code,
with the issue being very similar to the thread here:
http://lkml.org/lkml/2005/5/17/222 though was unable to trace the thread
to a conclusion to the specific problem itself. other than pointing at a
bug in kbuild system as per http://lkml.org/lkml/2005/5/18/293. But
U-boot version of kbuild does really seem to do "gcc
--print-file-name=include"

Commands:
make sandbox_defconfig
make V=1 C=2

If I do a 'ln -s /usr/lib/gcc/x86_64-linux-gnu/4.2.3/include/stdarg.h
include/' it goes thru this specific issue. the next issue is that it
compiles on a 32bit FC5, but fails on 64bit Ubuntu8.04.

Version of U-Boot V2: latest in git.
machine, gcc and sparse versions:
uname -a: Linux xxxxx 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC
2008 x86_64 GNU/Linux
gcc --version: gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7)
Sparse: tried with 2 of them:
[1] http://kernel.org/pub/software/devel/sparse/dist/sparse-0.4.1.tar.gz
[2]
