x32がコンパイルできるgcc-4.8のビルド手順必要パッケージのinstall
# yum groupinstall "Development Tools"

# yum install libgcc.i686 libstdc++-devel.{x86_64,i686}
# yum install zlib-devel.{x86_64,i686}

rawhideからgmp,mpfr,libmpc,gccのパッケージのsourceのrpmを持ってくる
gmp,mpfrでx86_64及びi686のパッケージを作成
$ cd rpmbuild/SPECS
$
32rpmbuild -bb gmp.spec
$ rpmbbuild -bb gmp.spec
$ su
# cd ../RPMS
# rpm -Uvh x86_64/gmp-{,devel-}5.1.1-2.fc18.x86_64.rpm i686/gmp-{,devel-}5.1.1-2.fc18.i686.rpm
# exit
$ 32rpmbuild -bb mpfr.spec
$ rpmbuild -bb mpfr.spec
$ su
# cd ../RPMS
# rpm -Uvh x86_64/mpfr-{,devel-}3.1.1-2.fc18.x86_64.rpm i686/mpfr-{,devel-}3.1.1-2.fc18.i686.rpm
# exit
libmpcは、f18のlibmpcとバッティングしているのでlibmpc48として、x86_64及びi686のパッケージを作成
$ 32rpmbuild -bb libmpc.spec
$ rpmbuild -bb libmpc.spec
$ su
# cd ../RPMS
# rpm -ivh x86_64/libmpc48-{,devel-}1.0.1-1.fc18.x86_64.rpm i686/libmpc48-{,devel-}1.0.1-1.fc18.i686.rpm
# exit
cloog-islはgccビルド時に作られるが今回はcloog48として別にx86_64及びi686を作成
$ 32rpmbuild -bb cloog48.spec
$ rpmbuild -bb cloog48.spec
$ su
# cd ../RPMS
# rpm -ivh x86_64/cloog48-{,devel-}0.18.0-0.fc18.x86_64.rpm i686/cloog48-{,devel-}0.18.0-0.fc18.i686.rpm
# exit
gcc.specのcloogの作成部分を無効にするように変更
libjavaのbuildで失敗するので,%{ix86}の時はjavaは無効にするように、gcc.specを変更
$ 32rpmbuild -bb gcc.spec
$ rpmbuild -bb gcc.spec
libtoolがgccのversionに依存しているので、rawhideのlibtoolのパッケージで作成
$ rpmbuild -bb libtool.spec
$ su
# cd ../RPMS
# rpm -Uvh x86_64/cpp-4.8.0-0.16.fc18.x86_64.rpm x86_64/gcc-4.8.0-0.16.fc18.x86_64.rpm x86_64/gcc-{c++,gnat,java,gfortran}-4.8.0-0.16.fc18.x86_64.rpm x86_64/libgcc-4.8.0-0.16.fc18.x86_64.rpm x86_64/libstdc++-{,devel-}4.8.0-0.16.fc18.x86_64.rpm x86_64/libgomp-4.8.0-0.16.fc18.x86_64.rpm x86_64/libquadmath-{,devel-}4.8.0-0.16.fc18.x86_64.rpm x86_64/libgfortran-4.8.0-0.16.fc18.x86_64.rpm x86_64/libgnat-{,devel-}4.8.0-0.16.fc18.x86_64.rpm x86_64/libgcj-{,devel-}4.8.0-0.16.fc18.x86_64.rpm x86_64/libtool-2.4.2-12.fc18.x86_64.rpm x86_64/libtool-ltdl-{,devel-}2.4.2-12.fc18.x86_64.rpm i686/libgcc-4.8.0-0.16.fc18.i686.rpm i686/libstdc++-{,devel-}4.8.0-0.16.fc18.i686.rpm i686/libquadmath-{,devel-}4.8.0-0.16.fc18.i686.rpm i686/libgfortran-4.8.0-0.16.fc18.i686.rpm
# exit
gcc-4.8のチェックも兼ねて、gmp,mpfr,libmpc,cloogの再作成
$ 32rpmbuild -bb gmp.spec
$ rpmbbuild -bb gmp.spec
$ 32rpmbuild -bb mpfr.spec
$ rpmbuild -bb mpfr.spec
$ 32rpmbuild -bb libmpc.spec
$ rpmbuild -bb libmpc.spec
$ 32rpmbuild -bb cloog48.spec
$ rpmbuild -bb cloog48.spec
$ su
# cd ../RPMS
# rpm -Uvh x86_64/gmp-{,devel-}5.1.1-2.fc18.x86_64.rpm i686/gmp-{,devel-}5.1.1-2.fc18.i686.rpm --force
# rpm -Uvh x86_64/mpfr-{,devel-}3.1.1-2.fc18.x86_64.rpm i686/mpfr-{,devel-}3.1.1-2.fc18.i686.rpm --force
# rpm -Uvh x86_64/libmpc48-{,devel-}1.0.1-1.fc18.x86_64.rpm i686/libmpc48-{,devel-}1.0.1-1.fc18.i686.rpm --force
# rpm -Uvh x86_64/cloog48-{,devel-}0.18.0-0.fc18.x86_64.rpm i686/cloog48-{,devel-}0.18.0-0.fc18.i686.rpm --force
# exit
--disable-bootstap ---with-multilib-list=m64,m32,mx32
の状態でgccを再ビルド
$ su
# cd /usr/include/gnu
# cp stubs-64.h stubs-x32.h
# exit
$ rpmbuild -bb gcc.spec
libgccのビルドで一度こけます。
$ su
# cd ../BUILD/gcc-4.8.0-20130307/obj-x86_64-redhat-linux/
# make install-gcc
# mkdir -p /usr/lib/gcc/x86_64-redhat-linux/4.8.0/x32/
# cd x86_64-redhat-linux/x32/libgcc
# cp crt*.o /usr/lib/gcc/x86_64-redhat-linux/4.8.0/x32
# cp libgcc*.a /usr/lib/gcc/x86_64-redhat-linux/4.8.0/x32
# exit
kernelを再ビルドして、x32abiを使えるようにします。
$ vi ../SOURCES/config-x86_64-generic
で、
CONFIG_X86_X32=y
にします。
$ rpmbuild -bb kernel.spec --with baseonly
$ su
# cd ../RPMS/x86_64
# rpm -ivh kernel-{,{devel,modules-extra}-}3.8.2-206.fc18.x86_64.rpm
# rpm -Uvh kernel-headers-3.8.2-206.fc18.x86_64.rpm
# reboot
これで、x32なglibcを作る準備ができました。
