ROS Fuerte snags on OSX Lion

edit

So I think I was finally able to install ROS Fuerte on Mac which cannot easily be accomplished by following religiously the tutorial in there as it keeps on hitting snags. Here are some error resolutions, which I'm not sure they are the optimal ones, maybe someone would like to confirm since I want to install UWSim but I cannot, which could be because of the osx not being ready for it:

rosdep install UWSim ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: UWSim: No definition of [libopenscenegraph] for OS [osx]

RESOLUTIONS

So open up your Terminal and put up aside the ROS installation tutorial I will try to follow up the problems as they emerge on the screen.

1) Right up from the beginning, the tutorial asks to write lines to your .bashrc file which is fine, except terminal each time you close and re-open a window is not calling this file, and yes I did go to Terminal > preferences > shell opens with: comand /bin/bash

So what I did was to write in .profile source ~/.bashrc which seems to solve this question, I saw in here that OS X doesn't read .bashrc file on bash start. Instead, it reads the following files (in the following order):

1. /etc/profile
2. ~/.bash_profile
3. ~/.bash_login
4. ~/.profile

2) If for any reason one of the instructions fails to install because of denied permissions as it will probably do on easy_install pip, one can "force" it by adding sudo before it.

3) When you are installing dependencies, log4cxx and swig-wx will turn into a headache.

i)Actually with this one I was not pleased with my solution but as I dug up on github comunity I could not find the proper solution. It snags in

system './autogen.sh'

and it fails to install log4cxx. What I did here was comment this line on the formula (/usr/local/Library/Formula/log4cxx.rb) and it seems to install fine but I'm unsure of it.

ii)Actually swig-wx was updated by Homebrew so if it fails to install just do the command again and it installs fine. If not go to this site which helped me before.

4) Next when it will probably fail to run the instruction make -j8... This has to do with the boost dependency. I could not figure out why but I downgraded it (boost 1.50.0 to boost 1.49.0) and then it'll work:

brew uninstall 
boost pushd $(brew --prefix) 
git checkout -f bf4f9aa Library/Formula/boost.rb 
popd 
brew install -v boost

5) It is quite confusing (and I still am a bit confused!!!) about the paths used to install the libraries. While it reads on the tutorial installation to send the files to /opt/ros/fuerte, usually the commands come up with ~/ros which will send you the files to the User. If you have installed ros-underlay to /opt/ros/fuerte, you should do the Desktop Full-Install on ... (more)
