Description Shelley Gong 2003-01-15 07:09:24 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
I try to build my own kernel from kernel source. I changed option -O2 in  CFLAGS
in /usr/src/linux-2.4/Makefile to -O -g. 
Then do make mrproper, make menuconfig, make bzImage, and then make modules.
During make modules, I got the following error message. 

gcc -D__KERNEL__ -I/usr/src/linux-2.4.18-14/include -Wall -Wstrict-prototypes
-Wno-trigraphs -O -g -fno-strict-aliasing -fno-common   -fomit-frame-pointer

Is it reproduceable?
If yes, please attach preprocessed tg3.i (add -save-temps to gcc options).

Comment 2 Jakub Jelinek 2004-10-03 19:37:40 UTC

No feedback, closing.  The kernel has built since then for many
people, so most likely this was a hardware issue.
