Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration.

I am very new to forum posting and also to Linux. I am currently trying to upgrade my kernel. I have followed following procedure. I am using RedHat
a. Downloaded latest kernel from kernel.org (220.127.116.11).
My kernel is - Linux 2.6.18-8.el5
b. Copied and extracted at /usr/src/linux-18.104.22.168/
c. Created .config using make gconfig
Till this it works fine. Problem starts now and I am searching the solution from last 2 days.
When I move forward to next step ‘make’ the output is as follow.
[root@localhost linux-22.214.171.124]# make
SYMLINK include/asm -> include/asm-x86
In file included from include/linux/compiler-gcc.h:86,
from kernel/bounds.c:9: include/linux/compiler-gcc4.h:8:4: error: #error Your version of gcc miscompiles the __weak directive
make: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2
To solve this I have Tried following:
a) I have tried to upgrade gcc by using CentOS distribution. I have installed following package to upgrade gcc
Using kernels other then official ones for CentOS/RHEL is totally stupid thing to do, since you lose ALL of the advantages of CentOS/RHEL, mostly stability. That is why (almost) nobody does it, and you will have REALLY BIG trouble to find someone to help you with that.
I , personaly, think it as a blasphemy. Just use some newer distro, do not taint CentOS/RHEL.
Another thing I thought may help, is to run all the commands as root, Just for the kernel compile "make" commands. As I have found recently, I need root access to configure a kernel, where previously I could do it as a ordinary user.
While searching for suitable guides, I also came across this web-site, dated 2006,
May still reveal some centos secrets. so don't tell anyone, just kidding!
If you need all modules and drivers enabled in CentOS kernel, then use kernels from centosplus repository.
CentOS kernels from base/os and updates repositories kernels are binary compatible with Red Hat compiled kernels since all kernel patches, bugfixes and any other changes are done in upstream (Red Hat) repositories, and only suggested by CentOS development team.
Centosplus repository is different story. All modules/drivers are enabled, and certain bugfixes and patches are introduced into the build. In last 3 years of use of centosplus kernels, I haven't found problems that are not found in upstream kernel so I consider them very safe. Definitely more safe then the kernel you can build by your self.
