Subject: A little problem.

Dear all,

I have a question about the kernel used by the RedHat. I am using Redhat 7.0
and upgrade the Linux Kerenl from their original 2.2.16 to 2.2.18. But when
I compile some modules, it said my kernel is 2.4.0. I check the
/usr/include/linux/version.h as follows, found that it shows I am using
Kernel 2.4.0.

#include <linux/rhconfig.h>
#if defined(__module__smp)
#define UTS_RELEASE "2.4.0-0.26smp"
#else
#define UTS_RELEASE "2.4.0-0.26"
#endif
#define LINUX_VERSION_CODE 132096
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))


But when I "cat /proc/version", it will give me:

Linux version 2.2.18-rtl (gcc version egcs-2.91.66 19990314/Linux
(egcs-1.1.2 release)) #1 Thu Apr 5 23:10:12 EDT 2001

So I am totally confused by the RedHat. So could you please tell me how to
solve this problem?

I just want to use the 2.2.18 without the 2.4.0. I did not install this one,
I also do not know where this one comes from.

Thanks in advance.

sounds to me like you have the wrong source in /usr/src/linux there is a
module you can install, or you can do it as I normally would...

obtain kernel source for 2.2.18 from ftp.kernel.org and put it in "/usr/src"
(/pub/linux/kernel/v2.2/linux-2.2.18.tar.bz2)

remove the symlink in /usr/src
"rm -f /usr/src/linux"

extract the new kernel source tree
"cd /usr/src ; tar xfI linux-2.2.18.tar.bz2"

rename the directory to kernel version and create symlink (for consistancy)
"mv linux linux-2.2.18 ; ln -s linux-2.2.18 linux"

No. It shows the headers your C compiler libraries are built againt. Which is
2.4 - and which is correct. It has nothing to do with the kernel you are
running

It is way OT here, but since Alan replied to this, I'll continue this
thread a bit: The interesting bit here, that I don't understand, is - how
in RedHat-7.0, that was released last year, libc is compiled against
2.4.0?... Did they include headers from one of pre / test versions?

Thanks
