RE: cross-compiler and stdarg.h

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) ?

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

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. :-)
