We need :
- Appimage file which we built on musl environment.
 - cp command.
 
The steps are pretty simple :
- 
Create special directory for our appimage and copy the appimage to the directory.
$ mkdir ~/appimage $ cp -r file-appimage ~/appimage/ $ cd ~/appimage - 
Extract the appimage file.
$ ./file-appimage --appimage-extract - 
Copy the ld-musl-x86_64.so.1 to /lib
$ sudo cp -r squash-root/lib/ld-musl-x86_64.so.1 /lib - 
Open the appimage file as usual.
$ ./file-appimage
