glibc make error: undefined reference to `__sync_fetch_and_add_4'

I am currently trying to compile glibc 2.6 from source, but during make, i get the following errors:

Code:

The only "solution" i've found for it is passing "-march=i486", but that fails for me--no such option. I have no idea how to fix this error. Any help is appreciated.

-march=i486 is a gcc flag
try

Code:

 
export CFLAGS="${CFLAGS} -march=i486"

i hope i wrote that right.

then in that same shell do your configure make

After doing that, i received the following:

Quote:

/media/sda4/sources/glibc-build/config.h:3:3: error: #error "glibc cannot be compiled without optimization"

I'm stuck again...

Okay, i managed to get by that error by checking out the default CFLAGS that gets generated in config.make without setting CFLAGS myself and adding -march=i486 to it on the next configure:

Code:

CFLAGS="-g -02 -march=i486"

But then i ran into this error:

Code:

/media/sda4/sources/glibc-build/libc_pic.os: In function `sync_file_range':
(.text+0x9e963): undefined reference to `.Lpseudo_end'
collect2: ld returned 1 exit status

Now i'm stuck again. Any one know how to get by this error? (Took a while just to get passed the previous error.)

I've been working through similar problems myself. I appear to have gotten further than you by leaving out the '-g'. It isn't really a optimization flag and is more for giving extra data to a debugger.
