下载代码
git clone https://salsa.debian.org/clint/fakeroot.git安装依赖
sudo apt-get install autoconf automake libtool升级autoconf到2.72
curl -k -J -O http://ftp.gnu.org/gnu/autoconf/autoconf-2.72.tar.xz
tar xf autoconf-2.72.tar.xz -C ./
cd autoconf-2.72/
./configure
make -j8
sudo make install开始编译
cd fakeroot
mdkir -p x86_64
autoreconf -f -i -Wall,no-obsolete
../configure --host=x86_64-linux-gnu --prefix=/usr --mandir=/usr/share/man --libdir=/usr/lib/x86_64-linux-gnu/libfakeroot --program-suffix=-sysv
make -j8还提示autoconf版本过低，则修改configue.ac注掉autoconf检查
