compiling kernel

Hi,

I try to compile my own kernel for my Indy.
I got the sources from cvs yesterday and made 

 make config
 make dep
 make clean
 make vmlinux

It compiles fine but it will not boot. I get the following message:

>> boot vmlinux

I used the Indy running Linux 2.1.121 from ftp.linux.sgi.com/pub/test
and egcs-1.0.2 from hardhat and also my i586 with the crosscompiler
from ftp.linux.sgi.com with the same results.
The vmlinux-indy-2.1.121.tar.gz boots fine.

What am I doing wrong?

This is usually because you didn't remove the "-N" in arch/mips/Makefile
or similiar. It's in the FAQ, but I keep forgetting that myself.

My problem is when I build the kernel, I get nothing at all.  I get the
first line, something like:

115360+19600+3136+334528+42744d+4248+6368 entry: 0x89fa8840                                                                           

then a blank line, then a total hang, mouse and keybaord included.

So can we detect the bad versions of binutils and automatically set the
LDFLAGS correctly?  I'm tired of forgetting. =)

Thank you. That helped. I read about this a few weeks ago but since I was
far away from compiling a kernel back then I did not remember it.

Looks like the console output is going to a serial line. Can you connect
over the network.
I do not have a keyboard, mouse and monitor. I get the console output to
the serial line.
Right now I get the output to my terminal but I can't get a login prompt.
However I can connect over the network.

Compiling kernel

[alad]

Hi,
     The question may sound very stupid... But I have following doubt.

suppose I am making some change in sched.c and now I want to build my kernel
that reflects the change..
Is there any way I can avoid answering all the questions when I do make zImage ?

In short how should I compile the kernel (in very small time) to see my changes.

Thanks (for not flaming me)

Assuming you have already configured your kernel and previously compiled
it then no questions should be asked. - The way I work is to do make
bzImage, try it, modify. make bzImage, try, etc... No questions asked.

If you did an accidental make mrproper or make clean in between then make
a copy of you old .config (I keep mine in /usr/src/my2.4.4config for
example so I would do from /usr/src/linux: cp ../my2.4.4config .config)
then run make oldconfig

followed by make dep && make bzImage

In future don't do a make mrproper or clean for that matter. All modified
files are automatically recompiled while non-modified ones are taken from
old compile. - This saves incredible amounts of time when using a Pentium
133 for development...

It sounds like you are running "make config" after you make your changes.
If you run "make oldconfig" instead of "make config" it will not ask you
questions unless you have added config options to the configure scripts.

Its probably not necessary to run either on of these if you have just made
minor changes to the code.  It does not hurt to do it though, and 
"make oldconfig" is fast.

Hope this helps,

compiling kernel

[Miguel González Castaños]

dear all,

 I have a 3com NIC card configured under RedHat 7.3.  The default kernel
recognizes perfectly the NIC card using the 3c515 driver.

 I am trying to compile the kernel 2.4.22 and it doesnt work. I have
looked around on the Internet and I have read that I need to use
ISA PnP. Does I just need to activate ISA PnP support in the kernel or I
have to do something else?

 Many thanks

 Miguel

    i build with 'isa pnp' enabled on everything, and have no use for it.

    being a little more specific as to 'where' you see a failure, would

Re: compiling kernel

Sorry for not being more precise...I meant that although with ifconfig using
the default kernel I got the interface up,
using the 2.4.22 kernel the network interface is down. I havent tried
anything else than doing a /etc/init.d/network restart.

hello again,

 When I said default kernel I meant the default kernel provided by RedHat in

Is there any way to get that .config file in those rpm kernels?

Re: compiling kernel

Its in your /boot directory.  Look for a file called 
config-REDHAT-RELEASE-NUMBER where REDHAT-RELEASE-NUMBER is the `uname 
-r` of the RedHat kernel RPM.  ie, if your running 2.4.20-20.9 like I 
am, look for /boot/config-2.4.20-20.9.  This file is a part of the 
kernel RPM that you installed (in my case, kernel-2.4.20-20.9.i586.rpm).

Re: compiling kernel

Just one question. This config file is changed after you boot the system and sets
all the modules that should be used, or it is
always the same config file? How is that file changed?

Many thanks in advance

Re: compiling kernel

[Kevin J. Cummings]

This file is put in the /boot directory by RedHat.  I suspect as a 
convenient place to store it, since you don't *have* to have the kernel 
sources installed.  You can also find various RedHat configuration files 
in /usr/src/linux/configs if you installed the kernel-source RPM. 
Whichever pre-built configuration you wish to start with, it should be 
moved to:  /usr/src/linux/.config in order to build an identically 
configured kernel as RedHat provides.

If you want to use it as a starting point for customizing your kernel,
copy it there, then run "make menuconfig" or "make xconfig" (and then 
"make depends") before building your new kernel (or modules).

Re: compiling kernel

[Miguel González Castaños]

hello again,

 I meant that if that .config file generated by the rpm kernel changes at
boot time. As Kevin has commented, I guess that It is the preconfigured
.config file for the rpm kernel.

 Many thanks

 Miguel
