error when building 32-bit linux kernel on 64-bit linux host

I am building 32-bit linux kernel on 64-bit linux host. (version 2.6.9 both on host and the target).

I'm compiling Linux kernel 2.6.15.5 and there is a problem

LDS arch/i386/kernel/vsyscall.lds AS arch/i386/kernel/vsyscall-int80.o AS arch/i386/kernel/vsyscall-note.o SYSCALL arch/i386/kernel/vsyscall-int80.so gcc: error: elf_i386: No such file or directory make[1]: *** [arch/i386/kernel/vsyscall-int80.so] Error 1

gcc version: 4.6

I am using Ubuntu-11.10 amd64 and trying to cross-compile a linux-2.6.38.8 kernel for a 32-bit target.I tried

make CROSS_COMPILE=i686-linux- ARCH=i386

But I got error

make: i686-linux-gcc: Command not found CHK include/linux/version.h CHK include/generated/utsrelease.h CC kernel/bounds.s /bin/sh: i686-linux-gcc: not found make[1]: *** [kernel/bounds.s] Error 127 make: *** [prepar

I'm following to this guide: http://fedoraproject.org/wiki/Building_a_custom_kernel But on this step rpmbuild -bb --target=`uname -m` kernel.spec I get the following errors:

Code: + mv kernel-3.1.0-i686-PAE.config .config ++ head -1 .config ++ cut -b 3- + Arch=i386 + make ARCH=i386 listnewconfig + grep -E '^CONFIG_' .config:4658:warning: override: reassigning to symbol DEBUG_BLK_CGROU

I have a driver source which includes linux/module.h. The following error occurred during compile. the kernel source is: 2.6.33.6-147.2.4fc13.i686 the compiler is: gcc-4.4.4-2.fc13.i686 Any hint or answer?

I recently mistakenly executed some commands I'd like to undo.

In an attempt to compile flightgear 2.8 for Ubuntu 12.04 I stupidly used the following commands from and OS/X guide:

export CFLAGS="-g -O2 -fPIC -arch i386 -arch x86_64"

and export CXXFLAGS="-g -O2 -fPIC -arch i386 -arch x86_64"

as well as cmake .

I am getting an error when running the following makefile with make -f makefile2 install (apart install the rest is working):

all:myapp

#which compiler CC = gcc

#Where to install INSTDIR = /usr/local/bin

#where are include files kept INCLUDE = .

#Options for development CFLAGS = -g -Wall -ansi

#Options for release # CFLAGS = -O -Wall -ansi

myapp: main.o 2.o 3.o $(CC) -o myapp main.o 2.o

Linux kernel stack corruption due to race condition with PTRACE_SETREGS -----------------------------------------------------------------------

A race conditon in ptrace can lead to kernel stack corruption and arbitrary kernel-mode code execution.

Kernel patch for easy reproduction:

diff --git a/arch/x86/kerne

The below is the error i'm getting while making a zImage.. Can anyone help me in this?
