[SKIP] No rule to make target None

edit

I have a problem that appeared overnight. All of my code is on an SVN and used to compile fine. This morning, I started getting this problem when compiling some packages:

[SKIP] No rule to make target None

I did not use the computer for about ten days because I was at a conference, but it was off so no updates were applied since the last time that I used it.

So here is what I tried.

roscreate-pkg foo
rosmake foo

And I got the same problem:

[ rosmake ] rosmake starting...

[ rosmake ] /home/robot/.ros/rosmake/rosmake_output-20120918-154406

I then applied all Ubuntu updates for 12.04, including all updates for ROS Fuerte. I created package foo2 and I still have the same problem. In my own packages, it seems like the build starts, but does not finish, because the ROS messages are not generated.
