Hi Radu,
I know what mercurial is and have used it in the past.  I was just confused as to why it issued the error at the beginning of my make.

I am running a pentium 4 2.6ghz running ubuntu 10.10.  What version information would be useful?

I am downloading diamondback as I type this.  Hopefully that will work!

Thanks much
Brian

What does the Failed to find rosdep mercurial warning mean?  It continues to build but that seems like a bad thing.

Mercurial is a DVCS that we use. Not sure why rosmake would issue those warnings -- my colleagues might be able to provide more information on that.

As always, in order to help you better, it's good to provide some information regarding your operating system, compiler, versions, etc.


Second,  As NI continues to make, I run into a segfault while trying to build pcl_ros.

  /opt/ros/cturtle/stacks/driver_common/dynamic_reconfigure/include/dynamic_reconfigure/server.h:73: internal compiler
error: Segmentation fault

An internal compiler error is a serious one, and I cannot think of a reason why compiling dynamic_reconfigure would give you that.

At this point, my recommendation for path of least pain is to install unstable or diamondback, and see if that works out.


Cheers,
Radu.
