# Running Command Line Application in Fedora Linux ARM using Rosetta 2

## Running steps

### Setup Rosseta 2 in Linux as shown in [01_rosetta2_fedora_linux_vm.md](https://gist.github.com/kid1412-net/362ed2c3b089a25f3667a27183da63e6#file-01_rosetta2_fedora_linux_vm-md)

### Install neccesary Linux x86-64 libraries

```
sudo mkdir /opt/packages

sudo dnf install glibc glibc.i686 libstdc++ --releasever=/ --forcearch=x86_64 --installroot=/opt/packages -y
```

### Create a symbolic link to Linux x86-64 library

```
sudo ln -s /opt/packages/lib64/ld-linux-x86-64.so.2 /lib64/
```

###  Download unrar Linux x86-64 binary

```
cd Downloads
wget https://www.rarlab.com/rar/rarlinux-x64-621.tar.gz
```

### Extract unrar Linux x86-64 binary

```
tar -xvzf rarlinux-x64-621.tar.gz -C .
```

### Check rar binary architecture

```
file rar/rar
rar: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, stripped
```

### Try to get help of rar Linux x86-64 binary

```
cd rar
LD_LIBRARY_PATH=/opt/packages/lib64 ./unrar /h
