Greetings,

currently we are maintaining own CentOS 7 i686 rebuild and I would like to kindly ask you to replace following macros from gcc.spec:

%if 0%{?rhel} >= 7
%ifarch %{ix86}
   --with-arch=x86-64 \
%endif
%ifarch x86_64
   --with-arch_32=x86-64 \
%endif

with that:

%if 0%{?rhel} >= 7
%ifarch %{ix86}
        --with-arch=i686 \
%endif
%ifarch x86_64
        --with-arch_32=i686 \
%endif

x86-64 causes gcc to use extended instruction set for produced code and it's impossible to run CentOS 7 i686 on older systems without SSE2 instruction because of SIGILL.

This affects Pentium 3, old VIA CPUs, old Xeons and some others.

Is that possible?

Thanks!

All,

The Beta release of the 32-bit (i686) Architecture of CentOS-7 (1503) is
currently on build logs.


Right now, only the boot.iso is available, but after some testing from
the users here with feedback, we can spin another tree with fixes and
actual installer isos.

http://buildlogs.centos.org/centos/7/os/i386/

updates are also here:

http://buildlogs.centos.org/centos/7/updates/i386/

Current known issues are:

1.  If installing on a QEMU (kvm) i386 VM, you must modify the VM cpu to
use "copy host cpu"

2.  The gnome desktop will not exit or log out from the menu.

If someone can figure out how to fix this issue, it would be much
appreciated :)

======================

Please report bugs on bugs.centos.org or to this Centos-Devel mailing
list will we do the beta testing and lets see if we can find/fix all the
issues before the full release of this arch.

Thanks,
Johnny Hughes
