Version control software is very important to use to keep track of changes. Today I was testing out the Xcode SCM (Software Configuration Management) integrated tools with SVN today and I had a few issues.

1. Xcode is trying to use the wrong dynamic libraries for SVN, if you update your SVN version to 1.6+. Since it’s referencing the wrong libraries you will get an error similar to this one:

Error: 155021 (Unsupported working copy format) please get a
newer Subversion client

I’ve seen this type of error when I upgraded my SVN and tried to use other SCM GUI software. To fix it I googled around and found some useful information at: Blind Genius Weblog

cd /usr/lib
sudo mkdir oldSVN
sudo mv libap*-1.dylib oldSVN
sudo mv libsvn*-1.dylib oldSVN
sudo mv libap*-1.0.dylib oldSVN
sudo mv libsvn*-1.0.dylib oldSVN
sudo ln -s /opt/subversion/lib/*-1.0.dylib .
sudo ln -s /opt/subversion/lib/*-1.dylib .

Instead of removing the library files, I moved them into a new directory as backup.

2. Now Xcode can use the correct updated libraries from SVN 1.6+, so I moved on to the next task of adding an existing project to the SVN repository. The tutorial at jms1.net was helpful in refreshing my memory for the SVN commands.

Make a project in Xcode and then use Terminal and execute the commands. If you aren’t familar with SVN check out the documentation.

cd LOCAL_PROJECT_PATH
svn mkdir SVN_REPOSITORY_LOCATION/PROJECT_NAME
svn co SVN_REPOSITORY_LOCATION/PROJECT_NAME .
svn add *
svn revert --recursive build
svn ps svn:ignore build .
svn ci

The commands create a folder in your SVN repository. Next it checks out the remote repository folder into the local project folder and add all of the project files. Once the files are “added” you’ll want to remove the build directory and ignore it from your SVN repository. Lastly it’ll commit the changes and you’re project is in the repository.

3. The project is in the repository and Xcode is using the latest version of SVN. You can use the SCM tools in Xcode to manage the project.

Today I worked on setting up Player/Stage on my Macbook Pro with Leopard 10.5.6 and I ran into a few issues.

I was using Macports 1.710 and I was attempting to install player-stage-player (2.03 2.1.2) and player-stage-stage (2.03 2.1.1) following a short guide at http://bentham.k2.t.u-tokyo.ac.jp/notebook/?p=247

If it’s your first time using macports it can take a long time. I waited 2+ hours to download/build/install dependencies

I used the command:

$ sudo port install playerstage-player playerstage-stage

However it errored out at the end with the message:

$ sudo port install playerstage-player playerstage-stage
--->  Building playerstage-player
Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_science_playerstage-player/work/player-2.0.4" && make all " returned error 2

So I searched around the MacPorts website and I came across the ticket #18891, which basically said to run the following command to change the version of python being used from 3.0 to 2.5.

$ sudo port install python_select && sudo python_select python25
Skipping org.macports.activate (python_select +darwin_9) since this
port is already active
--->  Cleaning python_select
Selecting version "python25" for python

Following that command I was able to finish installing Player/Stage via MacPorts by using the orginal port command.

$ sudo port install playerstage-player playerstage-stage

I tried to use player stage from MacPorts.

$ player /opt/local/var/macports/software/playerstage-stage\
/*/opt/local/share/stage/worlds/simple.cfg

And I received the error:

rr: unable to open color database /usr/X11R6/lib/X11/rgb.txt
 : No such file or directory (stage.c stg_lookup_color)

Following the advice from http://bentham.k2.t.u-tokyo.ac.jp/notebook/?cat=5 I added the following link.

$ sudo ln -s /usr/X11/share/X11/rgb.txt /usr/X11R6/lib/X11/rgb.txt

Now I am able to create a player server and connect with a client with the commands:

$ player /opt/local/var/macports/software/playerstage-stage\
/*/opt/local/share/stage/worlds/simple.cfg

/opt/local/var/macports/software/playerstage-player\
/*/opt/local/share/player/examples/libplayerc++/laserobstacleavoid

With the ability to run player/stage I will post again on my progress as I use an iPhone to run the Player client, rather than my Macbook Pro.
