LFS系统构建02-编译基本工具

¶LFS系统构建02-编译基本工具

¶Gnu Binutils

cd $LFS/sources
xz -d binutils-2.32.tar.xz
tar -xvf binutils-2.32.tar
cd binutils-2.32
mkdir -v build
cd build

#--prefix=/tools : 表示将编译后的文件存放到tools里
#--with-sysroot  : 表示讲$LFS设为编译的根目录
#--with-lib-path : 将静态库和动态库放入/tools/lib中
#--target        : 将编译中的对象文件放入$LFS_TGT中
../configure --prefix=/tools --with-sysroot=$LFS --with-lib-path=/tools/lib --target=$LFS_TGT --disable-nls --disable-werror
#编译
make 
#如果是x86_64,需要创建链接到/tools/lib64
case $(uname -m) in
x86_64) mkdir -v /tools/lib && ln -sv lib /tools/lib64 ;;
esac
#安装
make install

¶GCC

cd $LFS/sources
xz -d gcc-8.2.0.tar.xz
tar -xvf gcc-8.2.0.tar
cd gcc-8.2.0
#安装gcc需要gmp mpfr mpc
tar xvf ../gmp-6.1.2.tar.xz
mv -v gmp-6.1.2/ gmp
tar xvf ../mpfr-4.0.2.tar.xz
mv -v mpfr-4.0.2/ mpfr
tar -zxvf ../mpc-1.1.0.tar.gz
mv -v mpc-1.1.0/ mpc

#脚本
cd $LFS/sources/gcc-8.2.0/
for file in gcc/config/{linux,i386/linux{,64}}.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
#执行结果
'gcc/config/linux.h' -> 'gcc/config/linux.h.orig'
'gcc/config/i386/linux.h' -> 'gcc/config/i386/linux.h.orig'
'gcc/config/i386/linux64.h' -> 'gcc/config/i386/linux64.h.orig'


#设置64为库默认目录名称为lib

esac

mkdir -v build
cd build
../configure --target=$LFS_TGT --prefix=/tools --with-glibc-version=2.17 --with-sysroot=$LFS --with-newlib --without-headers --with-local-prefix=/tools --with-native-system-header-dir=/tools/include --disable-nls --disable-shared --disable-multilib --disable-decimal-float --disable-threads --disable-libatomic --disable-libgomp --disable-libmpx --disable-libquadmath --disable-libssp --disable-libvtv --disable-libstdcxx --enable-languages=c,c++
make
#错误
g++: internal compiler error: Killed (program cc1plus)
#原因
内存不足造成的
#解决
在虚拟机上可以重新给虚拟机分配更大的内存，我的虚拟机只分配了512M内存，直接就造成内存不足
如果还出现内存不足，那可以临时使用交换分区临来解决
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile
使用完之后，就删除
sudo swapoff /swapfile
sudo rm /swapfile

make install

¶Linux-4.20.12

cd $LFS/sources
tar xvf linux-4.20.12.tar.xz
cd linux-4.20.12
make mrproper
make INSTALL_HDR_PATH=dest headers_install
cp -rv dest/include/* /tools/include/

¶glibc

cd $LFS/sources
tar xvf glibc-2.29.tar.xz
cd glibc-2.29
mkdir -v build
cd build/
../configure --prefix=/tools --host=$LFS_TGT --build=$(../scripts/config.guess) --enable-kernel=3.10.0 --with-headers=/tools/include libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes
#编译错误(虚拟机centos编译错误,如果是实体机archlinux编译通过)
python版本需要3.7
make版本需要4.2
gmake是make命令的符号链接

#实体机编译安装完全通过
make 
make install

#测试
echo 'int main(){}' > dummy.c
$LFS_TGT-gcc dummy.c
readelf -l a.out | grep ': /tools'
#如果编译通过不会出现错误，并且会打印
[Requesting program interpreter: /tools/lib64/ld-linux-x86-64.so.2]
#然后删除测试文件
rm -v dummy.c a.out

¶Libstdc++

gcc包里面的一个子包

cd $LFS/sources/
tar xvf gcc-8.2.0.tar.xz
cd gcc-8.2.0
mkdir -v build
cd build/
../libstdc++-v3/configure --host=$LFS_TGT --prefix=/tools --disable-multilib --disable-nls --disable-libstdcxx-threads --disable-libstdcxx-pch --with-gxx-include-dir=/tools/$LFS_TGT/include/c++/8.2.0
make
make install

¶Binutils(第二次编译)

这一次编译使用第一次编译后的gcc来对其进行编译，以后的编译都会用属于lfs的gcc编译器来对包进行编译。这一次编译binutils，重新生成的binutils包依赖于新的gcc编译器，这使得整个工具链开始脱离宿主机，自形成体系

cd $LFS/sources/
cd binutils-2.32
mkdir -v build
cd build/
CC=$LFS_TGT-gcc AR=$LFS_TGT-ar RANLIB=$LFS_TGT-ranlib ../configure --prefix=/tools --disable-nls --disable-werror --with-lib-path=/tools/lib --with-sysroot
make
make install

#这个准备用在下一章
make -C ld clean
make -C ld LIB_PATH=/usr/lib:/lib
cp -v ld/ld-new /tools/bin

¶gcc(第二次编译)

第一次编译使用了宿主机的binutils工具集，因为binutils之前已经编译了，现在可以使用lfs的gcc和binutls来对gcc进行编译，使得编译后的gcc彻底成为lfs的编译器

cd $LFS/sources/
tar xvf gcc-8.2.0.tar.xz
cd gcc-8.2.0
cat gcc/limitx.h gcc/glimits.h gcc/limity.h > `dirname $($LFS_TGT-gcc -print-libgcc-file-name)`/include-fixed/limits.h

#脚本
for file in gcc/config/{linux,i386/linux{,64}}.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

case $(uname -m) in
x86_64)
