AppImage does not work on Alpine linux

[weyrick]

Hi Shannon, On Alpine linux (musl c) :
ldd ./pktvisor-x86_64-3.2.0.AppImage 
	/lib64/ld-linux-x86-64.so.2 (0x7f01ebc40000)
	libdl.so.2 => /lib64/ld-linux-x86-64.so.2 (0x7f01ebc40000)
	libpthread.so.0 => /lib64/ld-linux-x86-64.so.2 (0x7f01ebc40000)
	libz.so.1 => /lib/libz.so.1 (0x7f01ebc26000)
	libc.so.6 => /lib64/ld-linux-x86-64.so.2 (0x7f01ebc40000)
Error relocating ./pktvisor-x86_64-3.2.0.AppImage: gnu_dev_makedev: symbol not found

This appears to be related to AppImage/AppImageKit#1015

Note that on e.g. Ubuntu:

ldd ./pktvisor-x86_64.AppImage
	not a dynamic executable

glibc needs to be installed on Alpine Linux for AppImages to run.
At least until we can get them to work using https://git.adelielinux.org/adelie/gcompat/; it seems like AppImage/AppImageKit#1168 can be the key to this.

[probonopd]

With the static runtime, glibc no longer needs to be installed on Alpine Linux to run an AppImage (if what is inside the AppImage is either bundling everything, or is statically linked, or consists of platform-independent interpreted code/scripts).

[weyrick]

We've moved away from AppImage and now have static binaries.

[probonopd]

Just saying, if you put a static binary into an AppImage with the static runtime, then it can run on Alpine and other Linux distributions. (Why would one want to do such a thing? Maybe to bundle icons, translations, etc. alongside the application.)

Understood, thanks!
