-This is only useful for personally compiling Batocera, making PRs will be impossible (unless you're willing to add the affected files to the ignore list and manually merge any future changes made to them... which is pain).+Doing this will render it impossible to submit pull requests directly from this repository. If you choose to still proceed, you can use the LXC contained repository for testing things, and make the actual changes to an additional cloned local repository to make the pull request with.

 ===== Preparations ===== ===== Preparations =====
  
 For good security reasons LXC containers on Proxmox are running in unprivileged mode by default. It just keeps the container isolated from your Proxmox host and therefore from other different systems running on it. Nevertheless you have indeed the possibility to run an LXC container in privileged mode for whatever reason if you want to. When compiling Batocera on LXC containers be aware that both, unprivileged and privileged mode, need some minor preparations which will cover you from running into compile errors. For good security reasons LXC containers on Proxmox are running in unprivileged mode by default.

 +On your unprivileged or privileged LXC container command line do all the steps until the [[compile_batocera.linux#compilation|compilation]] step. Then, before starting to compile, do the following preparations for either unprivileged or privileged LXC containers:
