Description Michel Alexandre Salim 2003-09-29 23:45:42 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030703

Description of problem:
Red Hat ships gcc32 intended to be used for compiling kernels; however the
kernel-source RPM itself is still configured to use gcc32, which might lead
people to compile broken custom kernels.

A neat way is to provide a 'kgcc' package that contains either a symlink to
/usr/bin/gcc or /usr/bin/gccXX named 'kgcc', and have kernel-source always
specifying kgcc as its compiler.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. cat /usr/src/linux-2.4/Makefile | grep gcc

Actual Results:  HOSTCC          = gcc
CC              = $(CROSS_COMPILE)gcc

Expected Results:  HOSTCC          = kgcc
CC              = $(CROSS_COMPILE)kgcc

or at least

HOSTCC          = gcc32
CC              = $(CROSS_COMPILE)gcc32

Thanks, Michel and Arjan.  Unfortunately, even with this correction, I am 
still not able to compile the stock kernel source supplied with 094.  Output 
from the make shows the error:

Comment 2 Michael K. Johnson 2003-10-21 16:26:22 EDT
Dave, please patch the Makefile so that it uses gcc32
Comment 3 Dave Jones 2003-10-21 16:57:53 EDT
I can do this, however it won't fix the compile breakage above.
That's from Ingo's creative usage of CONFIG_ to work around limitations of the
2.4 build system.

Also note that building a kernel using rpm -b will DTRT, as it sets CC=gcc32 in
Comment 4 Michael K. Johnson 2003-10-27 11:59:15 EST
building from kernel-source package is important.

The other error should go away if you run "make oldconfig" (or run it
again).  Ugly hack.  :-(
