Hello,
I am compiling it from old kernel config.

[Kamranalilakhnavi]

I didn't choose any new option.

Please post output of following command.

# cd /usr/src/linux
# grep "CONFIG_UNIX98_PTYS" config

Hi Sir,

Pls check do you have all headers and their code is avaialble with that distribution and by the way what update you are using and what specific version you are using for security software.

If you are still getting that error, contact your vendor or its better to install following software but still you need source-code to compile it from source code. lets try it from www.kernel.org

following softwares are required for kernel that comes with RedHat Advance server update #2.

kernel-devel-2.6.9-22.EL
kernel-smp-devel-2.6.9-22.EL
kernel-doc-2.6.9-22.EL
kernel-2.6.9-22.EL
kernel-hugemem-devel-2.6.9-22.EL
kernel-utils-2.4-13.1.69

you pls check your side.

cd /usr/src/kernel/*EL-i686

My suggestion is that you should recompile your security software with that kernel version sourc-code that it prefers.

I believe he is trying to re-compile kernel so it does not need any kernel headers. As he is compiling from source.

Year Mr.Farrukh,

I know that what he asked for and I observe this thing number of times on RHEL thats why i am asking w.r.t to that headers, it will not start if some files are not there in.

/usr/include/

its impossible then.

Hello,
Kernel Version: 2.6.9-5.EL
Redhat: RHEL4


I have the following directories in
[root@station3 src]# pwd
/usr/src
[root@station3 src]# ls
kernels redhat
[root@station3 src]#
/usr/src/linux

[nomankhn]

Right,

now download the kernel from www.kernel.org and start its compilation.

Download this kernel and start compiling then

http://www.kernel.org/pub/linux/kernel/ ... .14.tar.gz
