Bug 156704 – udev with USE="selinux" missing a dependency

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Martin Meyer 2006-11-30 10:19:56 UTC]

I'm trying to build a system using the selinux/x86/2006.1 profile and my udev build is failing:

make: *** [udev_selinux.o] Error 1

!!! ERROR: sys-fs/udev-103 failed.
Call stack:
  ebuild.sh, line 1568:   Called dyn_compile
  ebuild.sh, line 937:   Called src_compile
  udev-103.ebuild, line 78:   Called die

A quick glance at the ebuild shows me no dependency on selinux-related anything, so I'm thinking that a dependency for sys-libs/libselinux is needed to make sure it is emerged before udev.

So the change I recommend is:
-DEPEND="sys-apps/hotplug-base"
+DEPEND="sys-apps/hotplug-base selinux? ( sys-libs/libselinux )"

This is assuming of course that libselinux actually provided that selinux/selinux.h header, which is a total assumption on my part as I've only just experienced the build failure and haven't ventured into fixing it yet.

[Comment 1 Martin Meyer 2006-11-30 10:27:37 UTC]

I've just confirmed that emerging libselinux first fixes the udev build problem.

And in case it wasn't clear before... I meant to change that DEPEND= line in sys-fs/udev/udev-103.ebuild.

yes, this is the right fix.

Added to udev-104.
