Need help getting it to run

[Brendan Erwin]

I'm using OS X 10.5 with macports.

I seem to have gotten past all the dependancies, but now its failing trying to load itself... Here is what I'm getting:

[11:17:12] Miracle-Max:$ /opt/local/bin/python2.5 Gui/Visualization.py
File "Gui/Visualization.py", line 12, in <module>
    from pycam.Geometry.utils import *
ImportError: No module named pycam.Geometry.utils

OR

[11:17:28] Miracle-Max:$ /opt/local/bin/python2.5 Gui/SimpleGui.py
Traceback (most recent call last):
  File "Gui/SimpleGui.py", line 11, in <module>
    from pycam import *
ImportError: No module named pycam

Any help?

Already I see what is probably the root of the problem.

I did a svn co and it has pycam.py whereas the release package does not.

Talking to myself here. :)

Now it's failing with "Bus Error" which I believe is a SegFault. I'm not sure how to go about working this problem.

[11:34:03] Miracle-Max:$ python -vd pycam.py
...A Bunch of Stuff...

Bus error

thanks for reporting the missing file. I added it and posted a new release.
as for the crash, I have no idea what causes it...
you could try deleting all *.pyc files and try again.

maybe try first to get some other Tk/TOGL/PyOpenGL based program to run and see if that works

[Brendan Erwin]

I'm able to get the PyopenGl demos to run.

I have found the line that is failing:

SimpleGUI.py -

class OpenglWidget(Opengl):
    def __init__(self, master=None, cnf={}, **kw):
        print "in OpenglWidget __init__"
        Opengl.__init__(self, master, kw)
        print "after Opengl.__init__"

I never get "after Opengl.__init__" to print, just the "Bus Error" message.

Does this mean anything to you?

[Lode Leroy]

did you compile PyOpenGL and TOGL yourself?
if not, I would suggest trying that first...

[Brendan Erwin]

I got it to work in Ubuntu. I'd say for now it just doesn't work on OS X.

Hi, new here.

I'm trying to run pycam.

On Ubuntu 8.04 LTS.

I've installed tcl/tk, togl, etc.

when I try to run pycam.py I get this: (A window pops up and then disappears, then I get this message on the command line)

xxxxxx@shuttle:~/Desktop/pycam-0.1.7$ python pycam.py
freeglut  ERROR:  Function <glutStrokeCharacter> called without first calling 'glutInit'.

Can you help me out with this?

Thank you.

Michael

Hi Michael ,
thanks for trying out pycam, and for reporting this bug.

you can either update to the latest svn version (41),
(http://pycam.svn.sourceforge.net/viewvc/pycam/trunk/pycam.tar.gz?view=tar)
or fix it yourself:

You need to add glutInit() on line 25 in pycam/Gui/SimpleGui.py

here is the diff....
