Lots of articles and posts on internet tell how to install the kernel sources for FreeBSD x-RELEASE versions, but none of them for X-STABLE.

For example, my FreeBSD version is 10.2-STABLE.
How can I install its kernel sources?

This method worked for me:

# pkg install devel/subversion
# svn checkout https://svn0.us-west.freebsd.org/base/stable/10 /usr/src
# cd /usr/src
# make clean

In order to find the sources for any other (i.e: future, older... etc) version, note the path in the URL: change 10 by 11 when published... and so on.

P.S: I don't know if the latest 'make clean' line is mandatory. I issued it, and the compilation worked.

  • The easiest way to find the sources is to go to svnweb.freebsd.org/base with your browser and... well, browse. And no, the "make clean" is not neccessary; freshly checked out sources are clean by definition. Commented Jan 27, 2016 at 11:46
