Hi. I'm trying to install the rust-1.31.1 package. During compilation an error occurs because the machine has less than 4GB of memory. So I created an overlay and changed the limit from 4GB to 3GB. # free -m total used free shared buff/cache available Mem: 3416 686 298 1 2432 2449 Swap: 8191 0 8191 I followed this guide: Local Overlay My steps: 1. Creating the local reposiotry mkdir /var/git/overlay cd /var/git/overlay git clone https://github.com/funtoo/skeleton-overlay.git myoverlay echo "myoverlay" > /var/git/overlay/myoverlay/profiles/repo_name 2. Editing the /etc/portage/repos.conf/myoverlay.conf file: # nano /etc/portage/repos.conf/myoverlay.conf [myoverlay] location = /var/git/overlay/myoverlay auto-sync = no priority = 10 3. Creating the ebuild's path: # install -d /var/git/overlay/myoverlay/dev-lang/rust # cd /var/git/overlay/myoverlay/dev-lang/rust # cp -r /var/git/meta-repo/kits/net-kit/dev-lang/rust/* . 4. Modifying the check parameter CHECKREQS_MEMORY="4G" by CHECKREQS_MEMORY="3G" into rust-1.31.1.ebuild. 5. Digesting the ebuild: # ebuild /var/git/overlay/myoverlay/dev-lang/rust/rust-1.31.1.ebuild digest >>> Creating Manifest for /var/git/overlay/myoverlay/dev-lang/rust After that all versions of rust were downloaded. by the ebuild command. 6.
