Glibc 1st pass wont compile (possibly i486 related)
 
Hi everyone,
I'm trying to compile Glibc-2.8-20080929 on Fedora10, as part of LFS6.4 chapter 5.7.

when i make glibc i get the following error message at the end of the compile:

Code:

make: *** [all] Error 2
Googling undefined reference to `__sync_val_compare_and_swap_4' reveals that this error generally occurs when -march=i486 isn't passed to the compiler. I've checked and triple checked that ive followed the instruction:
Code:
echo "CFLAGS += -march=i486 -mtune=native" > configparms
The above command is meant to be run in the glibc-build directory isn't it?

I've tried replacing CFLAGS += -march=i486 -mtune=native with CFLAGS += -march=i686 -mtune=native. After lookin at this thread, I tried both:
Code:
CFLAGS="-g -02 -march=i486"
and
Code:
CFLAGS=" -02 -march=i486"
All of the above combinations give the same error message during compilation. Does anyone know what I should try next to solve this problem?

Thanks

Also, every time I try a different configuration combination, should I start with a fresh build directory, or can I just run configure again?

try reinstalling your host OS.select all packages from package installation screen.then start lfs6.4 from begining.
i had similar problem.and i run

Code:
echo "CFLAGS += -march=i486 -mtune=native" > configparms
without it i ran into the error.

I know that bringing old posts back from the dead is looked down upon, but after months (on and off) of trying to fix this problem, I found a solution. Maybe if someone else finds this It'll save them some time and pain.

For some reason the CFLAGS weren't being passed from the configparams file to the compiler. All I had to do was export it as an environment variable:
Code:
export CFLAGS="-march=i486 -mtune=native -O2 -pipe"
Now I can (hopefully) move on without any further problems.
