LFS，编译自己的Linux系统 - 编译临时系统

编译GCC-4.8.2 PASS 1

解压并重命名

cd /mnt/lfs/sources
tar -Jxf ../mpfr-3.1.2.tar.xz
mv mpfr-3.1.2 mpfr
tar -Jxf ../gmp-5.1.3.tar.zx
mv gmp-5.1.3 gmp
tar -zxf ../mpc-1.0.2.tar.gz
mv mpc-1.0.2 mpc

修改GCC的配置文件

for file in \
 $(find gcc/config -name linux64.h -o -name linux.h -o -name sysv4.h)
do
  cp -uv $file{,.orig}
  sed -e 's@/lib\(64\)\?\(32\)\?/ld@/tools&@g' \
      -e 's@/usr@/tools@g' $file.orig > $file
  echo '
#undef STANDARD_STARTFILE_PREFIX_1
#undef STANDARD_STARTFILE_PREFIX_2
#define STANDARD_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDARD_STARTFILE_PREFIX_2 ""' >> $file
  touch $file.orig
done

sed -i '/k prot/agcc_cv_libc_provides_ssp=yes' gcc/configure

mkdir -v ../gcc-build
cd ../gcc-build
