Problems building the kernel using the ELDK

Problems building the kernel using the ELDK

[D'Abbraccio Joe-ljd015]

When I build the kernel using the ELDK I get the following failure:

Where is stdarg.h expected to come from if not from stdinc (i.e. -nostdinc).  I don't believe there is one in kernel distribution.

Thanks in advance,
Joe

I just had this problem and I'm embarassed to say I'm not quite sure
what caused it. I was building on a ppc64 box, but when I switched from
the ppc32 "cross-compiler" to the native toolchain (which is ppc32) the
problem went away.

Your cross-compiler includes this file in
<prefix>/lib/gcc-lib/powerpc-linux/<version>/include/ .

I had this problem too. A while ago. On 2002/09/13 I posted to this list but
with no success.

I found the problem in the main Makefile:

---------------
@@ -261,7 +262,7 @@
 # 'kbuild_2_4_nostdinc :=' or -I/usr/include for kernel code and you are not
UML
 # then your code is broken!  KAO.

-kbuild_2_4_nostdinc    := -nostdinc -iwithprefix include
+kbuild_2_4_nostdinc    := -nostdinc $(shell $(CC) -print-search-dirs | sed -ne
's/install: \(.*\)/-I \1include/gp')
 export kbuild_2_4_nostdinc

 export CPPFLAGS CFLAGS CFLAGS_KERNEL AFLAGS AFLAGS_KERNEL
---------------

I have no idea why... :o(

Cheers,

Steven

What's wrong with arch/ppc/8xx_io/uart.c and  arch/ppc/8260_io/uart.c ?

Well, I for one noticed it and am actually using the patch. :-)

[D'Abbraccio Joe-ljd015]

Doesn't this patch simply negate the -nostdinc switch (i.e. the resulting switch is something like "-I /usr/opt/eldk-1.0.1/usr/lib/gcc-lib/ppc-linux/2.95.3/include" which is part of stdinc) ?

It only negates _parts_ of -nostdinc. You are right in pointing out the
potential ugliness of this solution. The culprit lies IMHO pretty deep in
strong interconnection of components which is inherent to UNIX. (Note that
this is not meant to be flame bait, please ignore this mail if it offends
you. :-)
