[Xorp-users] XORP 1.6 support Click 1.6.0 ?

[Tom Gibson]

I don't think I ever got Xorp 1.6 working with Click in Linux, though I did
get a version out of source control at one point that worked.  I'm trying
now with the latest code and having trouble.  If anyone has advice on this
please let me know.

I've had minimal experience using cvs and have only so far used it to do a
checkout of latest code.  I should still have my code directory on my other
computer with the version of Xorp that worked though.  I'm guessing it
shouldn't be too hard to figure out a cvs command to do a "get" of code
current as of that date.

If I can figure out a small window of time in which the Click support was
fixed, what ways would be best to figure out what fixed it?
