Hi ya,

I have a Redhat 7.1 system practically out of the box, and though I 
had no problem compiling 2.4.9 the first time around, I can't 
recompile it at all without deleting the directory and untaring the 
distribution again. 

any ideas?

thanks in advance!

Fred

I start with the usual 
make mrproper
make xconfig ( I load a kernel config file - originally created with 
2.4.8) 
make bzImage
make modules
make modules_install
make install

(i've already edited lilo.conf and the links in the /boot directory)

Isn't it more safe to do it like this:

make mrproper
cp ../linux-2.4.8/.config .
make oldconfig
make xconfig
make bzImage && make modules && make modules_install && make install

?
I thought this was the proper way to do it, no?

additional info

recompiling results in parse errors immediately.

You don't need to make bzimage first, and you missed the dep/clean steps 
(theoretically not needed any more but I've had some really strange 
compiler errors by missing them out).

cp ../linux-2.4.8/.config .
make oldconfig
make xconfig
make dep clean install modules modules_install

OK, tried it, twice, still doesn't wan't to compile the second time.
Followed your instructions, twice. Then I deleted the directory, 
untarred again, reconfigured the kernel from scratch, made it the 
first pass. then it would not recompile after I ran 'make xconfig', 
saved, and tried to recompile with 'make install'. then I ran 'make 
mrproper', 'make xconfig', 'make dep', make install ----- broke again 
with the following perplexing errors.

all I can tell for sure is that the compiler doewn't seem to have a 
definition for FASTCALL.

thank you for your input.

Fred

/* rwsem.h: R/W semaphores implemented using XADD/CMPXCHG for i486+
 *
 * Written by David Howells (dhowells@redhat.com).
 *
 * Derived from asm-i386/semaphore.h
 *
 *
 * The MSW of the count is the negated number of active writers and waiting
 * lockers, and the LSW is the total number of active locks
 *
 * The lock count is initialized to 0 (no active and no waiting lockers).
 *
 * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an
 * uncontended lock. This can be determined because XADD returns the old value.
 * Readers increment by 1 and see a positive value when uncontended, negative
 * if there are writers (and maybe) readers waiting (in which case it goes to
 * sleep).
 *
 * The value of WAITING_BIAS supports up to 32766 waiting processes. This can
 * be extended to 65534 by manually checking the whole MSW rather than relying
 * on the S flag.
 *
 * The value of ACTIVE_BIAS supports up to 65535 active processes.
 *
 * This should be totally fair - if anything is waiting, a process that wants a
 * lock will go to the back of the queue. When the currently active lock is
 * released, if there's a writer at the front of the queue, then that and only
 * that will be woken up; if there's a bunch of consequtive readers at the
 * front, then they'll all be woken up, but no other readers will be.

What version gcc is that?
I think gcc 2.95.[23] or the superpatched 2.96.x is nice.
Maybe youre using egcs ?
I think that compiler is "old" from a 2.4.x (x>=6) point of view?

I'm using:

gcc-2.96-81  (redhat 7.1)

no egcs installed ??

I kinda figured that redhat would install the tools for a kernel 
compile. and what is  compat-egcs-6.2-1.1.2.14 that is shipped with 
redhat?

thanks 

Fred

That's the right one, it even installs under the name kgcc. You can then
set CC=kgcc in the kernel makefile.
