Player/Stage reinstallation process

Hi everyone:

Today I downloaded the .tar.gz of the latest versions of player and stage. I installed them according to the instructions included on the INSTALL.txt files. I had no trouble installing player, however, once again I had some problems while exporting the paths of the libraries that Stage requires.

The first problem I had after installing Stage and running the simple.cfg file was the following one:
layer: error while loading shared libraries: libplayerdrivers.so.3.0:
cannot open shared object file: No such file or directory

This problem I solved by making a symbolic link (with ldconfig).

After doing this, the drivers library was no longer a problem, However, the following errors were then displayed:


error : Failed to load plugin stageplugin.
error : libtool reports error: file not found
error : plugin search path: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/laura/playerstage/bin:/home/laura/playerstage/share/stage/worlds:/home/laura/Documents/Stage-3.2.0-Source/worlds:.:/usr/local/lib/
error : failed to load plugin: stageplugin
error : failed to parse config file simple.cfg driver blocks

The path being searched to find the plugin was quite disturbing... I remembered that I had already exported this paths during my first installation process some months ago.

I then eliminated some lines from the .bashrc files and made other exports with the help of Arturo and ended up with the following errors:

error : Failed to load plugin stageplugin.
error : libtool reports error: file not found
error : plugin search path: /home/laura/Documents/Stage-3.2.0-Source/worlds:.:/usr/local/lib/
error : failed to load plugin: stageplugin
error : failed to parse config file simple.cfg driver blocks

The path being searched now is only doubled, however we weren't able to find where was the first path located in order to get rid of it.

I also want to tell you that the newest versions of player stage have quite clear instructions in comparison with the previous ones. The indications of path exports are included and examples are relatively clear. This is why, if I don't find the solution to the path dilemma, I will start the installation all over again publishing every step I make in order for you to make some comments on the curious facts that you notice.

Regards!

Junta 14 de Octubre de 2009

Discutimos principalmente el mensaje de Renato referente a la instalación utilizando Synaptic.

Interpretando el mensaje de Renato, llegamos a la conclusión de que se desea el aprendizaje de herramientas de programación en Unix como Make, aprender a debugear, aprender a compilar etc. Esto con el objetivo de poder aplicar dichos conocimientos al hacer programas propios.

Acciones:

1. Verificar con Renato la versión que el está usando de Ubuntu para estar bien seguros de que es la misma.
2. Instalar Ubuntu y Player/Stage en la máquina de Laura primero y después en la de Oscar para verificar.
3. A la vez, seguir desarrollando el programa de navegación que sugirió Renato.

Sample navigation program and playernav codes

Hello everyone

Today I uploaded on Assembla the scripts related to the playernav util because the installation of player/stage with the synaptic package manager contains all of this programs already compiled. I got this codes from a backup I made of the files downloaded for my first attempt of installation (when I compiled everything). I started to take a look at this codes with Arturo and Carlos and I think it would be convenient for all of us to comment them in order to share our understanding.

I also downloaded the instructions for creating the sample navigation program, a pdf file located in the task with the same name (which was formerly assigned to Carlos L. and Luis). I think we have already understood how to create a player service (a cfg file). In fact, we have already done this with nero, adding the necessary drivers to achieve communication.

We have several player/stage documentation to read in order to understand the correct usage of the drivers and the libraries. However I think we will be able to make a significant advance throughout the next weeks.

Greetings!

Laura
