Subject: [gentoo-dev] virtual/linux-sources DEPEND non-inclusion reminder
Date: Fri, 17 Sep 2010 10:06:51
1 Just since it bit me on some infra boxes this evening, a quick reminder
2 that you should generally never DEPEND on virtual/linux-sources in your
3 ebuilds.
5 It's trivial to build a fully working system, and never have /usr/src
6 get populated.
8 1. Never RDEPEND on virtual/linux-sources, it will bring kernel sources
9 in during binpkg installs.
10 2. linux-mod.eclass does correctly bring in virtual/linux-sources as
11 needed, so if you are building kernel modules, inherit it rather than
12 including your own DEPEND for sources.
13 3. kernel_is: Version-specific virtual/linux-sources statements are generally
14 useless, as you have no idea what kernel version is at /usr/src/linux
15 or is pointed to by the various build variables. You should use the
16 kernel_is function of linux-info.eclass instead.
