@dormando, building RPM package for memcached 1.4.13 with default
"rpmmacros" options fails on RHEL-5 + i386 with same error:
thread.c:83: undefined reference to `__sync_add_and_fetch_2'
The ofender is -march=i386 flag exported via CFLAGS, I have fixed with
something like this:
# memcached 1.4.13 build fails on RHEL-5 + i386, offender is march gcc
flag => s/i386/i686
%ifarch %ix86
%if 0%{?rhel} == 5
CFLAGS='-O2 -g -march=i686 -mtune=i686'
export CFLAGS
%endif
%endif
This doesn't happen with other memcached versions.. and with .13 only
occurs on RHEL-5 + i386 platform, FYI.
