You _can_ do homebrew and macports at the same time, but there can be complications, like if your homebrew packages try to link against libraries from macports rather than the system ones, but homebrew was expecting the system one.  Usually you can work around those issues, but really you&#39;ll just have to try it out.  You could also build opencv-2.3.1 from source.  It is pretty easy to do, you can see my changes to the homebrew formula for opencv-2.3.1 here: <a href="https://github.com/wjwwood/homebrew/commit/41093ac462243224869b68473dd277a2b5ae4e3a">https://github.com/wjwwood/homebrew/commit/41093ac462243224869b68473dd277a2b5ae4e3a</a>  and you can probably work out how to build opencv manually from that file.<div>

To add to what John said, no this is not going to be as easy as Linux for now (we are working on that).  OpenCV should work, and usb cameras might work, but I haven&#39;t tried them.  <div><br></div><div>I don&#39;t know about the make eclipse-project command not working, could you give more detail on this (errors?)? </div>

<div><br></div><div>I would say that OS X right now is not ready for production work if you want rviz and the like to work.  If you are looking to get things done I would recommend using Linux until OS X support improves a little more over the next few months.</div>

<div>William and I have been working to get everything working on OS X, at this point we have made progress but its not as well tested as the linux distributions. </div>

I&#39;m trying to use ROS in MacOSX after successfully installing (not completely tested yet...stuff like rviz doesn&#39;t work...Ogre is ugly to install and it fails through macports). I&#39;m not sure what to expect ...will other things be as simple to just install and play like in Linux? Will OpenCV work? will my uvc cameras work? <div>








<br></div><div>I would like people&#39;s opinions about this transition (please, don&#39;t bash me for the ridiculous question). I would like to have a feel of how many actual mac users are having ROS working successfully. As I said, my roscore works and got the desktop-full install fine (no errors), but I ran into the case where rviz is there but it&#39;s NOT there really...</div>








<div><br></div><div>Why does stuff like &quot;make eclipse-project&quot; doesn&#39;t work in here?</div><div><br></div><div>Thanks for the positive/negative vibes to whoever feels my position.</div><div><br></div><font color="#888888"><div>
