I am looking for package manager and App manager implementation using c++ on embedded linux with consideration of app manager scenario (run/pause/resume/exit/recovery) with below packaging features.
(1) installation of package
(2) uninstallation of package
(3) package factory reset
(3) package integrity check
I have considered ipkg , opkg, conan and dpkg packages but those are very heavy and can't be considered on embedded linux device . So It looks like I need to implement my own pakcage manager which will do packaging by copying binary ,resource and configuration files to a package directory and after that need to calculate the checksum for file integrity ( using sha256) so that during uninstallation of package same can be achieved by verifying the checksum of package and after that need to implement package signing . So thought to discuss if any library I can use to impose this functionality on my c++ code then it will be really helpful. Apart from this App manager is also required which will manage app operation like run/pause/resume/exit/recovery once installation take place successfully on the device. App manager I had considered dbus and systemd but due to negative performance need to drop them. Please advise so that I can move forward on this.
