bash: ./make_ext4fs: No such file or directory 错误解决方法(应用是32位的)

一般出现该错误是由于应用程序是32位导致的，可以使用file命令来查看：

[cpp] view plain copy print?wsh@ubuntu:~/Desktop file make_ext4fs   </span></span></li><li class=""><span>make_ext4fs: ELF 32-bit LSB  executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), <span class="keyword">for</span><span> GNU/Linux 2.6.8, not stripped  </span></span></li><li class="alt"><span>wsh@ubuntu:~/Desktop

wsh@ubuntu:~/Desktop$ file make_ext4fs
make_ext4fs: ELF 32-bit LSB  executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, not stripped
wsh@ubuntu:~/Desktop$

可以从上面看到make_ext4fs为32位程序，所以我们需要让64位机支持运行32位应用。
执行下面两条命令即可解决问题：

[cpp] view plain copy print?sudo apt-get install lib32c-dev

sudo apt-get install lib32c-dev

[cpp] view plain copy print?sudo apt-get install lib32stdc++6

sudo apt-get install lib32stdc++6

再运行make_ext4fs就不会报错了：

[cpp] view plain copy print?wsh@ubuntu:~/Desktop ./make_ext4fs   </span></span></li><li class=""><span>Expected filename after options  </span></li><li class="alt"><span>make_ext4fs [ -l <len> ] [ -j <journal size> ] [ -b <block_size> ]  </span></li><li class=""><span>    [ -g <blocks per group> ] [ -i <inodes> ] [ -I <inode size> ]  </span></li><li class="alt"><span>    [ -L <label> ] [ -f ] [ -a <android mountpoint> ]  </span></li><li class=""><span>    [ -S file_contexts ]  </span></li><li class="alt"><span>    [ -z | -s ] [ -w ] [ -c ] [ -J ] [ -v ]  </span></li><li class=""><span>    <filename> [<directory>]  </span></li><li class="alt"><span>wsh@ubuntu:~/Desktop
