connecting client to local server

[saintpaulCollege]

I've installed the dev environment for 0.70 (think I fixed all the pathing issues) and I'm using Panda. I get a local server running (using full-1999 template)
However, when I try to connect with the client, I get a pair of exceptions - one unhandled because its of type string.
The following are the exception stacktraces. Any ideas of what I'm doing wrong?

Did you initialize your server? That error usually means there was a problem validating your username or password. Check the server log messages and you'll probably see something more clear. As a side note, I'm not sure why that shows up like that in the 0.70 release since that error message is garbled due to a bug in the Twisted library that was fixed between 0.60 and 0.70.

Thanks,
Mike

I cleared out the .mv3d folder to reinitialize the server again. Upon doing so, I get the same string of exceptions as before:
Do you have an idea of what my issue is?
thanks

Was there an exception in the server log? Was that the server log? It sort of looked like the client to me. You can copy the server log to the clipboard in Overseer by selecting multiple lines and using Ctrl+C. Also the log is saved in the .mv3d folder under the server name you specified. Did that error come up when you used the initialize button or while you were trying to log in after using it?

The other thing that comes to mind is that the initialize process may not have been finished. There isn't currently a progress bar for it and it can take a minute or two. It prints a message about being complete to the log when it's done.

Hope that helps..

Thanks,

Mike

that was a copy from the console after I told the overseer to initialize. Below I have pasted the log .mv3d/overseer

There was not attempt to run a client. I started overseer, choose a full-1999 template, and clicked initialize. This was what happened

The unfortunate thing here is that this is an exception in the exception handling code, so it's showing that and not the underlying problem. Oh hey, I just noticed this:

Code: Select all

File "C:\Python26\lib\site-packages\twisted\spread\pb.py", line 474, in printTraceback

That looks like maybe you already had Twisted installed since the dev env installer puts it in C:\Projects\Twisted. It's possible there's some conflict there. I haven't seen that exact error message before, so it's hard to say. One thing that could help would be to change the error handling code so it isn't masking the problem. If and you open up C:\Projects\MV3D\trunk\mv3d\tools\guidewx.py and change this: (starting at line: 3901)

Code: Select all

class ErrorWindow(object):
    """
    Brings up an error window.
    """
    def __init__(self, parser, error, reason):
        errorType = ".".join([error.type.__module__, error.type.__name__])
        if reason is None:
            reason = errorType
        errorValue = "%s: %s" % (errorType, str(error.value))
        text = "%s\n\n%s" % (errorValue, error.getTraceback())
        self.window = MessageDialog(parent=parser, text=text,
            title=reason, iconType=DialogIcon.error)
        self.window.show()
        parser.setClipboard(text)


To this:

Code: Select all

class ErrorWindow(object):
    """
    Brings up an error window.
    """
    def __init__(self, parser, error, reason):
        errorType = ".".join([error.type.__module__, error.type.__name__])
        if reason is None:
            reason = errorType
        errorValue = "%s: %s" % (errorType, str(error.value))
        print errorValue
        deferr(error)


That might shed some light on the situation. It's possibly some sort of configuration issue or a problem with the version of Twisted you have installed. I'm not totally sure. Also, I'm assuming this is in overseer.log. Is there a server-Full-1999.log as well?

Thanks,

Mike

I did that, I guess I've two things for you now:
1. First is the exception read out
2. The server-Full-1999.log

exceptions.NameError: global name 'ode' is not defined


Aha! That looks to be the problem. It seems like pyode isn't installed or it isn't in your path. Can you try this on a command line?

Code: Select all

c:\> python
>>> import ode


I'm guessing it will fail with an ImportError. Make sure you have pyode installed and that it's in your Python path. The dev env installer should have installed it to the correct location. I was having some troubles with ode.dll conflicting with Panda3D's ode installation. If that's the case, find ode.dll and copy it to your Panda bin directory. This is what the dev env installer tries to do:

Code: Select all

CopyFiles "C:\Panda3D-1.7.2\python\ode.dll" "C:\Panda3D-1.7.2\bin"


But that relies on Panda 1.7.2 being installed (which is the version the dev installer installs) and it being in the default location. If that isn't the case with your system, you'll have to make a similar copy of ode.dll. I should file a bug for it to try and figure out where Panda is installed if you aren't having the dev installer do it for you.

Hope that helps!

[saintpaulCollege]

I am able to import ode without an issue
I guess I'm not sure what you mean by "I'll have to make a similar copy of ode.dll"
I actually find 4 separate copies of ode.dll - in python26, panda3d-x.x.x/bin, panda3d-x.x.x/python, and in combinator_paths_bincache
Though each one is a different file (different sizes and such)

[SirGolan]

I think the one in panda3d-x.x.x/python should be the correct one. Try saving backups of the others and then copying that one on top of them.
