Nevermind, problem has been solved RE: [Edu-sig] no Python 2.0 bindings for Lightflow until now ...

[Charlie Derr]

Sorry for the clutter.  Markus already pointed me in the right direction,
and I've been playing with Lightflow (on linux at least), and it's great!!!!

|Hi all,
|	I hope you'll forgive this tech-support-like question being
|posted to a
|non-tech-support list, but there's been so much discussion about Lightflow
|here, that I thought someone would be bound to know the answer...
|
|	I am an enthusiastic (but not so very experienced)
|pythonista.  I just
|downloaded the lightflow python module for windows (NT in my case).  I have
|python 1.5 installed, but the instructions in the Lightflow documentation
|don't seem to make much sense to me.

|The following example is one of the simplest possible scenes that can be
|rendered: a sphere in the empty space.
|Now start your preferred text editor and type the following text. When you
|have finished save it in a file, and then start python from a console
|passing the file name as an input (for example, if you have saved the file
|as example.py, just type: python example.py).

|My problem is that this doesn't really look like python to me.
|I'm guessing
|it's either c or c++.  When i follow the instructions given above the code
|(i pasted the code into a file exam.py) , i get:
|
|Microsoft(R) Windows NT(TM)
|(C) Copyright 1985-1996 Microsoft Corp.
|
|C:\>cd python
|
|C:\Python>cd lf
|
|C:\Python\lf>ls
|Lightflow  exam.py
|
|C:\Python\lf>python exam.py
|  File "exam.py", line 3
|    void main(void)
|            ^
|SyntaxError: invalid syntax
|
|
|
|Do i need to use gcc to compile this file first?  (I have the
|cygwin port of
|gcc, but am unfamiliar with its use)  I tried, but it wasn't able to find
|the included header file.    While you folks are answering (or not) I'll be
|trying to get lightflow to work on linux -- maybe this stuff makes more
|sense there.

|
|	thanx very much for any information,
