Many # things can be the cause to this, but I believe that it is due to gcc3 # still having issues with optimizations, or with it not filtering bad # combinations (protecting the user maybe from himeself) yet. # # This can clearly be seen in large builds like glibc, where too aggressive # CFLAGS cause the tests to fail miserbly. # # Quote from Nick Jones , who in my opinion # knows what he is talking about: # # People really shouldn't force code-specific options on... It's a # bad idea. The -march options aren't just to look pretty. They enable # options that are sensible (and include sse,mmx,3dnow when apropriate). # # The next command strips CFLAGS and CXXFLAGS from nearly all flags. If # you do not like it, comment it, but do not bugreport if you run into # problems. # # (13 Oct 2002) strip-flags # Lock glibc at -O2 -- linuxthreads needs it and we want to be conservative here export CFLAGS="${CFLAGS//-O?} -O2" export CXXFLAGS="${CFLAGS}" NPTL_VER="0.39" BRANCH_UPDATE="20030517-1" # Minimum kernel version for --enable-kernel export MIN_KV="2.4.1" # Minimum kernel version for enabling TLS and NPTL ... # NOTE: do not change this if you do not know what # you are doing ! export MIN_NPTL_KV="2.5.50" MY_PV="${PV/_}" S="${WORKDIR}/${P%_*}" DESCRIPTION="GNU libc6 (also called glibc2) C library" SRC_URI="http://ftp.gnu.org/gnu/glibc/glibc-${MY_PV}.tar.bz2 ftp://sources.redhat.com/pub/glibc/snapshots/glibc-${MY_PV}.tar.bz2 http://ftp.gnu.org/gnu/glibc/glibc-linuxthreads-${MY_PV}.tar.bz2 ftp://sources.redhat.com/pub/glibc/snapshots/glibc-linuxthreads-${MY_PV}.tar.bz2 nptl?
