I managed to get it to compile with a 16GB ramdisk using "system-llvm": $ grep -r rust /etc/portage /etc/portage/profile/package.use.mask:dev-lang/rust -system-llvm /etc/portage/package.use/rust:dev-lang/rust system-llvm parallel-compiler It claims it wants: Checking for at least 13312 MiB >From the build-log: ====== * Final size of build directory: 12344956 KiB ( 11.7 GiB) * Final size of installed tree: 366492 KiB (357.9 MiB) * The ebuild is installing to one or more unexpected paths: * * /usr/share/doc/rust-1.51.0 * * Please fix the ebuild to use correct FHS/Gentoo policy paths. ======= Hope this helps, Joost
