util-linux源码下载： git clone git@github.com:util-linux/util-linux.git 或者 https://mirrors.edge.kernel.org/pub/linux/utils/util-linux/
执行 git tag 查看有哪些发行版本，这里切换到v2.39.2版本：
git checkout v2.39.2
交叉编译工具链：gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu
交叉编译步骤
1. 导出交叉编译工具链环境变量
export PATH=/usr/local/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/bin:$PATH
这里根据你的交叉编译工具链的位置进行相应的调整，我这里是把工具链放在了/usr/local目录下了。
2. 执行autogen.sh生成configure
./autogen.sh
3. 新建build目录用来安装编译后的库和可执行程序
mkdir build
4. 执行configure生成Makefile文件
./configure --host=aarch64-linux-gnu --prefix=/root/util-linux/build
- --host=HOST cross-compile to build programs to run on HOST [BUILD]
-
--prefix=PREFIX install architecture-independent files in PREFIX [/usr]
5. 编译
make
编译的时候报如下错误：
/usr/local/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/bin/../lib/gcc/aarch64-linux-gnu/7.2.1/../../../../aarch64-linux-gnu/bin/ld: cannot find -ltinfo collect2: error: ld returned 1 exit status make[2]: *** [Makefile:7857: dmesg] Error 1 make[2]: Leaving directory '/root/util-linux' make[1]: *** [Makefile:15786: all-recursive] Error 1 make[1]: Leaving directory '/root/util-linux' make: *** [Makefile:6695: all] Error 2
解决办法：
在执行 configure 的时候加上 --without-tinfo 选项。
./configure --host=aarch64-linux-gnu --prefix=/root/util-linux/build --without-tinfo
make
configure 执行完成，继续编译的时候又出现新的错误，如下：
In file included from /usr/include/python2.7/Python.h:8:0, from libmount/python/pylibmount.h:4, from libmount/python/context.c:21: /usr/include/python2.7/pyconfig.h:12:12: fatal error: aarch64-linux-gnu/python2.7/pyconfig.h: No such file or directory # include <aarch64-linux-gnu/python2.7/pyconfig.h> ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated.
解决办法：
在执行 configure 的时候加上 --disable-pylibmount 选项。
./configure --host=aarch64-linux-gnu --prefix=/root/util-linux/build --without-tinfo make
静静等待编译完成。编译完成后执行 make install 进行安装，安装完成后在build目录下有如下内容：
