Description GianpaMX 2017-01-18 16:59:00 UTC
I'm emerging `runc` due to an `emerge --update --deep --with-bdeps=y --newuse @world`

Emerge is updating `containerd` and as a dependency `runc`
    These are the packages that would be merged, in reverse order:
    ...
    [nomerge       ] app-emulation/docker-1.11.0 
    [ebuild     U  ]  app-emulation/containerd-0.2.5 [0.2.0] USE="-hardened%" 
    [ebuild     U  ]   app-emulation/runc-1.0.0_rc2-r2 [0.1.0] USE="(-apparmor) -hardened%" 

But fails at Compiling source...

Reproducible: Always

Steps to Reproduce:
1. emerge "=app-emulation/runc-1.0.0_rc2-r2"

Actual Results:

Comment 2 Simon 2017-01-18 18:55:44 UTC
Can confirm to have to same/a similar issues since upgrading from run-0.1.0 to runc-1.0.0_rc2. Strange thing is that for me the emerge doesn't actually fail (which might be a bug in Portage?) yet the build still throws errors and Docker doesn't work anymore afterwards

The two lines that jump out are:
ln: .gopath/src/..: cannot overwrite directory
fatal: Not a git repository (or any of the parent directories): .git

Especially the second one sounds like it should be fatal and thus the emerge should fail, but it didn't.


Full output below:
~ ❯ sudo emerge --ask --tree --verbose --oneshot --getbinpkg=n runc            

These are the packages that would be merged, in reverse order:

Calculating dependencies... done!

Would you like to merge these packages? [Yes/No] yes

Comment 3 Manuel Rüger (RETIRED) gentoo-dev 2017-01-23 20:01:30 UTC
Which version of dev-lang/go is installed on this system?
Comment 4 Simon 2017-01-23 20:16:15 UTC
I'm on version 1.7.4
Comment 5 GianpaMX 2017-01-24 02:48:00 UTC
Mine is dev-lang/go-1.4.2:0
Comment 6 Manuel Rüger (RETIRED) gentoo-dev 2017-01-24 16:34:15 UTC
(In reply to Juan Villa from comment #5)
> Mine is dev-lang/go-1.4.2:0

Please update to latest dev-lang/go-1.7.4 and see if it still fails.
Comment 7 GianpaMX 2017-01-25 04:20:41 UTC
Now I got the same error as Simon
