I wanted my Rasperry Pi 2, which was running LibreELEC, to additionally scan for specific network devices. I didn’t want to change the LibreELEC, as I was very satisfied with it. So here’s how I managed to cross-compile on my linux box the tool `arp-scan`.<\/p>\n
1.) Get the LibreELEC.tv-Source and compile an image.<\/p>\n
Make sure that this works before continuing with anything else. I managed to compile the 9.0-devel version.<\/p>\n
Instructions are given on the LibreELEC-Wiki<\/a><\/p>\n 2.) Create the arp-scan directory and the package.mk<\/p>\n 3.) Add needed patches<\/p>\n To get a patch-File from a github-commit, you can just add `.patch` to the url and you’ll get a correct patchable diff.<\/p>\n I needed the change for the cross compilation, but the author hadn’t released a new version yet, so I had to download and include the patch:<\/p>\n Sadly this won’t help with the release file, as the configure script already exists. So we have to delete the configure-File to force the package-System to run „autoconf“. That’s the reason for the `post_patch()`-Section in the package.mk.<\/p>\n 4.) Add ourself to the dependency tree<\/p>\n 5.) Copy resulting file to host I wanted my Rasperry Pi 2, which was running LibreELEC, to additionally scan for specific network devices.
