I was going to let this die but since it came up again. We have already
added one other distro to our list and if we have sufficient interest in
others we will add these too.
This is not a CW for RedHat release this will be CodeWarrior for Linux.

When you compile your kernel it will create a system.map and all you need
to do is: cp system.map /boot/system.map-2.2.14 (whatever versison kernel
numbers -2.2.14 for example)
Make sure you type the command "lilo" before you reboot!
I always copy the system.map after copying bzImage to the /boot directory
and then run lilo
Note depmod will list any modules not used by your new kernel they are not
errors ok?
Example I don't use SCSI cards so I have compiled them out of my kernel.
depmod will reflect that fact and list them.

James

Hi,
I have recompiled my 2.2.14 kernel and installed it.
But when i want to insmod some modules, the kernel says :
kernel_version needed, but can't be found
Is there any option i should turn on to compile the kernel?

You need to tell gcc that it needs to link with libpthread - add
-lpthread
to the end of the gcc command line.

Also, you should never include system headers using the quoted

Don't worry too much about that. It is used by some GUI admin program
which can manage the /etc/conf.modules file. The module-info file
contains information about parameters you can specify for each loaded
module, and that information doesn't change when you re-compile the
kernel, and in most cases not even when you upgrade to a newer kernel.
System.map is only essential for kernel logging and that only for fatal
kernel error messages; and also for the ps command to display the symbol
name in the WCHAN column when you do "ps l".

Don't ask questions like this in here!
This is mainly a question of taste.
I use emacs or vi together with gcc/g++

You are of course right here.
The transparent compression patches for ext2 can be found here:
http://www.netspace.net.au/~reiter/e2compr/
There is also the "double" driver on
http://perso.cybercable.fr/verbavat/double/
It gives the compression on the block device level. It is a bit outdated
(the latest patches are for kernel 2.0).

Strange. I have a 80386 based computer (yes, it is over 10 years old).
There are 17 GB IDE hard disk and IDE CDROM inside. Everything works fine
with the oldest possible IDE controller (ISA card), only e2fsck takes
quite long time to finish its job. Did you try to tell setup the disk geometry
with the real number of sectors and heads, but cylinders limited to 1024,
then create a 1 cylinder partition for booting and tell linux via lilo
the real geometry?

When you built the new kernel, did you also do
# make modules
# make modules_install

It is very much a matter of personal taste. If you like a GUI, Kdevelop is
quite good and getting better rapidly. If you like the green-screen stuff,
emacs is powerful and many people use vi.
