Ups, I missed the last part. As you say, leaving CFLAGS intact will probably make -i586 problem free. Tiago On Wed, Jun 9, 2010 at 11:38 PM, Tiago Marques tiago...@gmail.com wrote: On Tue, Jun 8, 2010 at 5:27 AM, Daniel Drake d...@laptop.org wrote: On 7 June 2010 20:05, James Cameron

In another thread, we've been discussing the issue that Fedora 12 changed base architecture from i586 to i686. The XO-1 processor (Geode LX) is a i586. Fedora 12 seems to run OK (although I suspect there will be a few broken packages), but Fedora 13 is more obviously broken (for a start, glibc
