Hello,

I am trying to install ROS on Mac OS X Snow Leopard. I am getting this error message, when trying to install the ros base (or any other configuration) e.g. by executing rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=electric&variant=ros-base&overlay=no"

Bootstrapping ROS build
Detected ros_comm bootstrapping it too.
Rospack failed to build

    raise CalledProcessError(retcode, cmd) 
subprocess.CalledProcessError: Command source /Users/shoefer/ros/setup.sh &&  rosmake ros ros_comm --rosdep-install returned non-zero exit status 255

I done everything according to the installation manual, I have installed all necessary packages via MacPorts, activated the MacPorts python 2.6 version etc. I have also checked that I have YAML and boost installed.

Any help would be appreciated!

I just followed the same instructions on Mac OS X 10.5.8, and I did not run into any problems.

Ok I have found the source of the problem: rosmake was unable to build rospack and rosstack. When invoking make manually in /Users/shoefer/ros/ros/tools/rospack/ the following error occurs:

macbook:/Users/shoefer/ros/ros/tools/rospack/ shoefer$ make
 /Users/shoefer/ros/ros/tools/rospack/rospack.cpp: In member function 'void rospack::ROSPack::crawl_for_packages(bool)':
 /Users/shoefer/ros/ros/tools/rospack/rospack.cpp:1933: error: 'PATH_MAX' was not declared in this scope
 /Users/shoefer/ros/ros/tools/rospack/rospack.cpp:1935: error: 'tmp_cache_dir' was not declared in this scope
 /Users/shoefer/ros/ros/tools/rospack/rospack.cpp:1945: error: 'tmp_cache_path' was not declared in this scope

This is a problem of my gcc version which is gcc-mp-4.4 (installed via Macports). The default gcc shipped with XCode (on my machine it is gcc-4.2) does actually define PATH_MAX. So to be safe one should better use a different gcc version, but a quick hack actually also did the job, namely defining PATH_MAX manually in rospack.cpp and rosstack.cpp:

 #define PATH_MAX   256

Maybe it would be a good idea to check if PATH_MAX is defined to prevent other users from getting into the same trouble. Any comments on that?
