Description Aldo Mazzeo 2016-10-12 17:58:24 UTC
The ebuild for the new net-im/skypeforlinux doesn't perform the required operations to make it working on with the pax_kernel IUSE: i.e. disabling MPROTECT in such case.
As far as I can see, the code is already in the ebuild, but it has been commented out. Is it possible to re-enable it?

Anyway, here's my emerge --info:

Comment 1 Raymond Jennings 2016-10-12 20:26:13 UTC
I'm afraid I'm not familiar with the concept, but I did see the comments.

Does anyone know if this stuff was commented out because it only applies to the classic version?
Comment 2 Aldo Mazzeo 2016-10-13 19:31:15 UTC
Well, the command line in the ebuild comment is more or less correct. I had to run "paxctl -Cm /opt/skypeforlinux/skypeforlinux" on my console to have the binary correctly running on my gentoo system.

So, it's just a matter of fixing the path in the ebuild file and IMHO it should work.
Comment 3 Raymond Jennings 2016-10-22 01:21:25 UTC
PR merged, fixed version is now in the master portage tree.

stable mirror has already caught up, rsync users please be patient.
