Thread: Tutorial for installing pycar on Linux

i got error

Hi all,

First post here even if I read the forums on a regular basis.

well it's about 3 days I tries to configure pycar on a debian.
I have one installed on an EPIA PD 6000 and one at work on a Dell PIV.

I have the same problems on both.
Python 2.3 is installed, directfb, pymedia, pydfb, pygame and so on.

First under X, if I launch pycar with python pycar.py . the error is still:

Traceback (most recent call last):
File "pycar.py", line 250, in ?

YV12_OVERLAY= pygame.YV12_OVERLAY
AttributeError: 'module' object has no attribute 'YV12_OVERLAY'

Then I try on console, so no X, only framebuffer, with an export PYCAR_DISPLAY=directfb

Am I missing something ?

I know a bit about linux as I feel better with BSD systems.

I had no time to check under FreeBSD on the EPIA, I might give it a try, but I wanted to use a linux distro to be able to do some wardriving too as some applications are not fully ported under FBSD.

Thanks a lot !!

Ok, I had a little time to test something else.

I compiled pydfb, pymedia from cvs and got pycar from cvs too.

I copied the deepsea skin from the iso into the skins directory.
I copied the i18n/en to i18n/fr.
I desactivated all the modules but settings because audio and video where crashing pycar.

Well I'm stuck on this:

I tried to understand the code but short named vars are awfull to read and follow.
Would it be possible to use vars that mean something ?

I'd like to help as far as I can.

Cheers.

Try to:
print a[ 2 ]
before that s.blit. It might be None or invalid.
In case if it is None, use this:

Code:

if len( a )> 2 and a[ 2 ]!= None:

Sorry for short names but they are defined locally. Sort of i, j, k in C

Thanks,
seems to run a bit better.

In the skins action.xml and cfg I saw many getActiveArea(), getActiveScreen() and so on, ending in error.
Apparently, they need to be sourced as common.getActiveArea().

This way, if I only enable settings in pycar.cfg, I'm able to launch the frontend.
But it crashes with 'module' object has no attribute 'abstractlist'

It looks like it's in skins/deepsea/settings_actions.xml

a= val( 'areas', 'logo_dialog' )
menu.abstractList.init( [ { 'title': x } for x in settings.xmlSettings.getValue( 'logos' )[ 1 ] ] )
a.init( "menu.abstractList, 0" )
a.setParams( _('Select logo from the list'), '', common.getActiveArea(), ('logo_change',item) )

Well I continue to check

I thought I posted a reply, but apparently the reply is gone with my windoze crash.

I reloaded the pycar from the sourceforge cvs today.

Here's what I have now:

i have the same error, with todays (10-27-2006) CVS version of pycar with debian on a EPIA-MII

does anybody have an idea where to check?

I'm putting a computer into my car, it will be this one running Debian.

I'm working through what I need to know about installing and configuring pycar (as that seems to be the only game in town AFAICT) by messing with the install in a virtual machine via VMware. I have pycar and seemingly all of its dependent software parts installed.

When I run I get a brief screen showing "Loading..." then a stack trace (this is typed by hand because I don't have any X in the virtual machine yet):

Code:

    audio.player.startPlayback( pos )

Looks like the config file is missing something?
