Thanks to index5 in Discord.
Creates LOVE AppImage by compiling every single dependency from source.
You may want to grab all dependencies required by SDL, but not the SDL itself.
Note for Ubuntu ARM64: If APT can't find libsndio-dev and fcitx-libs-dev, make sure to add universe repository!
libsndio-dev
fcitx-libs-dev
universe
Afterwards, run make. love-main.AppImage (by default) will be generated. See the Makefile script for various tweakable variables.
make
love-main.AppImage
If you're running WSL 1, run make QEMU=env instead to bypass FUSE requirement restrictions by extrating appimagetool somewhere else first.
make QEMU=env
appimagetool
AppRun.c is based on default AppImage's AppRun.c thus it's under MIT license.
The rest is public domain.
