按照手册指引
make 然后 ./fshow 然后就
cannot execute binary file: Exec format error
发现所有可执行文件均无法执行，搜索一下该错误，多与在32位系统下运行64位程序有关。
然而本机与系统均是64位，可能需要安装相关支持。
搜索ubuntu18.04安装32位支持环境安装相关依赖，无效。
考虑wsl的问题。

Edit: requires "Fall Creators Update", 1709, build 16299 or newer (I think)
Presuming a fresh Ubuntu WSL instance, you'll need to install the qemu-user-static package, add the i386 >binfmt, enable the i386 architecture, update your package lists, and install some i386 packages:
Install qemu and binfmt
sudo apt update sudo apt install qemu-user-static sudo update-binfmts --install i386 /usr/bin/qemu-i386-static --magic >'\x7fELF\x01\x01\x01\x03\x00\x00\x00\x00\x00\x00\x00\x00\x03\x00\x03\x00\x01\x00\x00\x00' --mask >'\xff\xff\xff\xff\xff\xff\xff\xfc\xff\xff\xff\xff\xff\xff\xff\xff\xf8\xff\xff\xff\xff\xff\xff\xff'[Edit: whoops, need to update package lists, added sudo apt update]
This will activate i386 support by causing them to be executed through qemu-i386-static, and drop a config file into /var/lib/binfmts/ for future reactivation.
You will need to reactivate this every time you restart WSL and want i386 support:
sudo service binfmt-support start
Enable i386 architecture and packages
sudo dpkg --add-architecture i386 sudo apt update sudo apt install gcc:i386 /*wrong in my wsl but can still run programs correctly*/
