Hi,
I have some problems compiling Squid-3.2.3 on Centos 5.5 or older Fedora
boxes (all 32bit).
Squid 3.1.x worked just fine on the very same servers.
Compiling on Centos 6.0 (64bit) works fine too.
This didn't work out:
export CFLAGS="${CFLAGS} -march=i486"
http://www.linuxquestions.org/questions/linux-software-2/glibc-make-error-undefined-reference-to-%60__sync_fetch_and_add_4-a-571961/
Here are the error messages when compiling Squid:
