Versions 0.12, 0.12.1.1_pre and 9999 all exhibit the same problem. If I try to debug the ebuild by manually performing the compile instructions manually, they work fine. The kernel is correctly configured. The problem appears to be in the "make install-all" (assuming that's run) stage, and I think is because the module's being built to the wrong directory, or something similar. It must be something weird about my portage/kernel configuration, as others seem to have no problem. I'll attach a build log, and the output of running the bits manually. I'm running kernel 5.5.13-gentoo, same problem with kernel 5.4.28-gentoo. My make.conf says "-j12", but the same happens with "-j1".

Something weird. I tried: cd /usr/portage/media-video/v4l2loopback ebuild v4l2loopback-0.12.1.1_pre.ebuild install and got: make[1]: Entering directory '/usr/src/linux-5.5.13-gentoo' /bin/sh: 1: cannot create /var/tmp/tmpdir/portage/media-video/v4l2loopback-0.12.1.1_pre/work/v4l2loopback-0.12.1.1_pre/v4l2loopback.mod: Permission denied /bin/sh: 1: cannot create /var/tmp/tmpdir/portage/media-video/v4l2loopback-0.12.1.1_pre/work/v4l2loopback-0.12.1.1_pre/.v4l2loopback.mod.cmd: Permission denied so it's something to do with permissions. Said directory is owned by portage:portage, but I could make it work with: FEATURES="-userpriv" Now it's not me! To attempt to install v4l2loopback, I had a few pre-requisites, and they installed fine. So it's summat specific to this ebuild and FEATURES="userpriv".
Unfortunately, I've been unable to reproduce this. Does the issue persist?
Compiles OK with 0.12.5 (i.e. keyworded ~amd64); still broken with 0.12, but I don't mind that. Feel free to close it.
