i'm trying to build the 2.4.20 kernel in RH 8.0 and i keep having the same problem. the make dep, make bzImage commands both work fine. But during the make modules i get the following error:

gcc -E -D__KERNEL__ -I/usr/src/linux-2.4.20/include -traditional -DCHIP=710 fake7.c | grep -v '^#' | perl -s script_asm.pl -ncr710
script_asm.pl : Illegal combination of registers in line 72 : MOVE CTEST7 & 0xef TO CTEST7
Either source and destination registers must be the same,
or either source or destination register must be SFBR.
make[2]: *** [sim710_d.h] Error 255
make[2]: Leaving directory `/usr/src/linux-2.4.20/drivers/scsi'
make[1]: *** [_modsubdir_scsi] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.20/drivers'
make: *** [_mod_drivers] Error 2


I've tried it with the stock RH gcc version 3.2-7, with 3.2.1, and with the 2.95.3, which the kernel's readme specifically says to use, but i get the problem every time. Any ideas?

for some reason it is not able to compile a module for the scsi drivers go through config again and try taking out any scsi modules that you are sure you dont need and try it again

Hello,

I have the same problem on RH compiling 2.4.20. I read somewhere that it is due to gcc incompatibility. Not sure how to fix other than trying to install the older gcc (ver?)

Cheers,
Senthil

What version of gcc are you running?

I am running gcc-3.2.7. Kernel 2.4.18-14 that comes with RH 8 compiles fine. rpm -qa | grep gcc yielded the following -

gcc-gnat-3.2-7
compat-gcc-objc-7.3-2.96.110
compat-gcc-c++-7.3-2.96.110
libgcc-3.2-7
gcc-g77-3.2-7
gcc-java-3.2-7
gcc-c++-3.2-7
compat-gcc-7.3-2.96.110
compat-gcc-java-7.3-2.96.110
gcc-3.2-7
compat-gcc-g77-7.3-2.96.110
gcc-objc-3.2-7

I fixed this by modifying drivers/scsi/script_asm.pl

on line 585, change
$dst_reg = "\U$1\E";
$rest = $2;

to
$dst_reg = $1;
$rest = $2;
$dst_reg =~ tr/a-z/A-Z/;

I had to do "make mrproper; "etc. to rebuild the kernel
