Please see the following howto which I just verified on latest Debian version: > # Setup Gentoo chroot using stage3 > cd /tmp > mkdir /tmp/gentoo > wget > http://distfiles.gentoo.org/releases/amd64/autobuilds/20200101T214502Z/stage3-amd64-20200101T214502Z.tar.xz > tar -xaf stage3-amd64-*.tar.xz -C /tmp/gentoo > mount -t proc /proc gentoo/proc > mount --rbind /sys gentoo/sys > mount --make-rslave gentoo/sys > mount --rbind /dev gentoo/dev > mount --make-rslave gentoo/dev > > # Chroot into Gentoo > env -i HOME=/root TERM=$TERM $(which chroot) /tmp/gentoo /bin/bash --login > > # In Gentoo chroot... > export PS1="(chroot) $PS1" > > # Make sure name resolution works... > echo 'nameserver 8.8.8.8' > /etc/resolv.conf > > # Get latest daily portage snapshot > emerge-webrsync > > # Tell portage we want FEATURES=test for sys-apps/grep > mkdir /etc/portage/env > echo 'FEATURES="test"' > /etc/portage/env/run-tests.conf > echo 'sys-apps/grep run-tests.conf' >> /etc/portage/package.env > > # Build dev-libs/libpcre without jit to trigger the error > echo 'dev-libs/libpcre -jit' >> /etc/portage/package.use/gnu_bug29446 > emerge -1 dev-libs/libpcre > > # Chdir to grep ebuild > cd $(portageq get_repo_path / gentoo)/sys-apps/grep > > # Normally you would use `emerge ...` to install package and all deps, but > because we don't want to merge package on disk and are only interested in > running tests manually, we will use `ebuild` command > ebuild grep-3.3-r1.ebuild clean test > > # You should now see test 'pcre-jitstack' failing. > # Feel free to inspect source and run test again: > su portage --shell /bin/bash > > # As portage use, chdir into work dir > cd ~/sys-apps/grep-3.3-r1/work/grep-3.3 > > make check TESTS=pcre-jitstack -- Regards, Thomas Deutschmann / Gentoo Linux Developer C4DD 695F A713 8F24 2AA1 5638 5849 7EE5 1D5D 74A5
