七. 构建临时系统
1. 通用编译指南
a. 确认是否正确设置了 LFS
环境变量
echo $LFS
b. 假定你已经正确地设置了宿主系统的符号链接:
1)shell 使用的是 bash。
2)sh 是到 bash 的符号链接。
3)/usr/bin/awk 是到 gawk 的符号链接。
4)/usr/bin/yacc 是到 bison 的符号链接或者一个执行 bison 的小脚本。
c. 构建临时系统中,确保解压软件包时你使用的是 lfs 用户。
d. 除非特别说明,删除解压出来的目录和所有编译过程中生成的
目录。<package>
-build
2. Binutils-2.25 - 第一遍
cd $LFS/sources tar -jxf binutils-2.25.tar.bz2 cd binutils-2.25 mkdir -v ../binutils-build # 建议在源码目录之外一个专门的编译目录里面编译 cd ../binutils-build ../binutils-2.25/configure \ --prefix=/tools \ --with-sysroot=$LFS \ --with-lib-path=/tools/lib \ --target=$LFS_TGT \ --disable-nls \ --disable-werror make # 如果是在 x86_64 上编译,创建符号链接,以确保工具链的完整性 case $(uname -m) in x86_64) mkdir -v /tools/lib && ln -sv lib /tools/lib64 ;; esac make install rm -rf $LFS/sources/binutils-build rm -rf $LFS/sources/binutils-2.25
3. GCC-4.9.2 - 第一遍
cd $LFS/sources tar -jxf gcc-4.9.2.tar.bz2 cd gcc-4.9.2 tar -xf ../mpfr-3.1.2.tar.xz mv -v mpfr-3.1.2 mpfr tar -xf ../gmp-6.0.0a.tar.xz mv -v gmp-6.0.0 gmp tar -xf ../mpc-1.0.2.tar.gz mv -v mpc-1.0.2 mpc for file in $(find gcc/config -name linux64.h -o -name linux.h -o -name sysv4.h) do cp -uv $file{,.orig} sed -e ‘[email protected]/lib\(64\)\?\(32\)\?/[email protected]/tools&@g‘ \ -e ‘[email protected]/[email protected]/[email protected]‘ $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 $file.orig done sed -i ‘/k prot/agcc_cv_libc_provides_ssp=yes‘ gcc/configure mkdir -v ../gcc-build cd ../gcc-build ../gcc-4.9.2/configure \ --target=$LFS_TGT \ --prefix=/tools \ --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-libitm \ --disable-libquadmath \ --disable-libsanitizer \ --disable-libssp \ --disable-libvtv \ --disable-libcilkrts \ --disable-libstdc++-v3 \ --enable-languages=c,c++ make make install rm -rf $LFS/sources/gcc-build rm -rf $LFS/sources/gcc-4.9.2
4. Linux-3.19 API 头文件
cd $LFS/sources tar -Jxf linux-3.19.tar.xz cd linux-3.19 make mrproper make INSTALL_HDR_PATH=dest headers_install cp -rv dest/include/* /tools/include rm -rf $LFS/sources/linux-3.19
5. Glibc-2.21
cd $LFS/sources tar -Jxf glibc-2.21.tar.xz cd glibc-2.21 if [ ! -r /usr/include/rpc/types.h ]; then su -c ‘mkdir -pv /usr/include/rpc‘ su -c ‘cp -v sunrpc/rpc/*.h /usr/include/rpc‘ fi sed -e ‘/ia32/s/^/1:/‘ \ -e ‘/SSE2/s/^1://‘ \ -i sysdeps/i386/i686/multiarch/mempcpy_chk.S mkdir -v ../glibc-build cd ../glibc-build ../glibc-2.21/configure \ --prefix=/tools \ --host=$LFS_TGT \ --build=$(../glibc-2.21/scripts/config.guess) \ --disable-profile \ --enable-kernel=2.6.32 \ --with-headers=/tools/include \ libc_cv_forced_unwind=yes \ libc_cv_ctors_header=yes \ libc_cv_c_cleanup=yes make make install rm -rf $LFS/sources/glibc-build rm -rf $LFS/sources/glibc-2.21
6. 确认新工具链的基本功能(编译和链接)都是像预期的那样正常工作。运行下面的命令进行全面的检查:
echo ‘main(){}‘ > dummy.c $LFS_TGT-gcc dummy.c readelf -l a.out | grep ‘: /tools‘
如果一切工作正常的话,这里应该没有错误,最后一个命令的输出形式会是:
[Requesting program interpreter: /tools/lib/ld-linux.so.2]
注意 /tools/lib
、或者 64 位机器的 /tools/lib64
会以动态链接器的前缀出现。
一旦一切都顺利,清理测试文件:
rm -v dummy.c a.out
7. Libstdc++-4.9.2
cd $LFS/sources tar -jxf gcc-4.9.2.tar.bz2 cd gcc-4.9.2 mkdir -pv ../gcc-build cd ../gcc-build ../gcc-4.9.2/libstdc++-v3/configure \ --host=$LFS_TGT \ --prefix=/tools \ --disable-multilib \ --disable-shared \ --disable-nls \ --disable-libstdcxx-threads \ --disable-libstdcxx-pch \ --with-gxx-include-dir=/tools/$LFS_TGT/include/c++/4.9.2 make make install rm -rf $LFS/sources/gcc-build rm -rf $LFS/sources/gcc-4.9.2
8. Binutils-2.25 - 第2遍
cd $LFS/sources tar -jxf binutils-2.25.tar.bz2 cd binutils-2.25 mkdir -v ../binutils-build cd ../binutils-build CC=$LFS_TGT-gcc \ AR=$LFS_TGT-ar \ RANLIB=$LFS_TGT-ranlib ../binutils-2.25/configure \ --prefix=/tools \ --disable-nls \ --disable-werror \ --with-lib-path=/tools/lib \ --with-sysroot make make install rm -rf $LFS/sources/binutils-build rm -rf $LFS/sources/binutils-2.25
9. 现在,为接下来的“再调整”阶段准备链接器:
make -C ld clean make -C ld LIB_PATH=/usr/lib:/lib cp -v ld/ld-new /tools/bin
10. GCC-4.9.2 - 第2遍
cd $LFS/sources tar -jxf gcc-4.9.2.tar.bz2 cd gcc-4.9.2 cat gcc/limitx.h gcc/glimits.h gcc/limity.h > \ `dirname $($LFS_TGT-gcc -print-libgcc-file-name)`/include-fixed/limits.h for file in $(find gcc/config -name linux64.h -o -name linux.h -o -name sysv4.h) do cp -uv $file{,.orig} sed -e ‘[email protected]/lib\(64\)\?\(32\)\?/[email protected]/tools&@g‘ \ -e ‘[email protected]/[email protected]/[email protected]‘ $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 $file.orig done tar -xf ../mpfr-3.1.2.tar.xz mv -v mpfr-3.1.2 mpfr tar -xf ../gmp-6.0.0a.tar.xz mv -v gmp-6.0.0 gmp tar -xf ../mpc-1.0.2.tar.gz mv -v mpc-1.0.2 mpc mkdir -v ../gcc-build cd ../gcc-build CC=$LFS_TGT-gcc \ CXX=$LFS_TGT-g++ \ AR=$LFS_TGT-ar \ RANLIB=$LFS_TGT-ranlib ../gcc-4.9.2/configure \ --prefix=/tools \ --with-local-prefix=/tools \ --with-native-system-header-dir=/tools/include \ --enable-languages=c,c++ \ --disable-libstdcxx-pch \ --disable-multilib \ --disable-bootstrap \ --disable-libgomp make make install ln -sv gcc /tools/bin/cc rm -rf $LFS/sources/gcc-build rm -rf $LFS/sources/gcc-4.9.2
11. 确认新工具链的基本功能(编译和链接)都是像预期的那样正常工作。运行下面的命令进行全面的检查:
echo ‘main(){}‘ > dummy.c cc dummy.c readelf -l a.out | grep ‘: /tools‘
如果一切工作正常的话,这里应该没有错误,最后一个命令的输出形式会是:
[Requesting program interpreter: /tools/lib/ld-linux.so.2]
注意 /tools/lib
、或者 64 位机器的 /tools/lib64
会以动态链接器的前缀出现。
一旦一切都顺利,清理测试文件:
rm -v dummy.c a.out

36. 清理无用内容
此步骤是可选的,但如果你的 LFS 分区容量比较小,知道有些不必要的内容可以被删除也是挺好的。
cd ~ strip --strip-debug /tools/lib/* /usr/bin/strip --strip-unneeded /tools/{,s}bin/* rm -rf /tools/{,share}/{info,man,doc}
37. 改变属主
以后部分的命令都必须以 root
用户身份执行而不再是 lfs
用户。当前,$LFS/tools
目录属于 lfs
用户,
通过下面的命令将 $LFS/tools
目录的属主改为 root
用户:
exit chown -R root:root $LFS/tools
38. 备份$LFS/tools
目录
可用于构建额外的相同版本 LFS 系统。后面的指令将对当前的工具做些调整,导致在构建新系统时会失效。
