[visionegg] Re: py2exe and VisionEgg

Hi, Andrew, 

Fixed the problem below, as had forgotten to add the file pyz_support.py.

I modified the build-win-exe-demos.py script to work with just one simple demo
file (such as texture.py) instead of all the VisionEgg demos, for testing
purposes.  After adding pyz_support.py, now I am getting an executable in the
sumo directory, albeit with less-than-stellar results (i.e, executing the file
does nothing).  I have made sure to copy PyWinTypes23.dll into the sumo
directory.

Running the build-win-exe-demos.py script now gives the following results:

C:\Python23\VISION~1>build-win-exe-demos.py
C:\Python23\python.exe C:\python23\lib\site-packages\Installer\Makespec.py --noc

I've gotten Installer to work fine with simpler pygame scripts, but still having
trouble with visionegg.  any ideas as to why the build-win-exe-demos.py script
is failing?

thanks!

Hi, Andrew, 

Thanks for the tips!  Theoretically, working just fine, but I think I might have
a problem, either with my python install or with some other little issue.

running the build-win-exe-demos.py file gets the following errors:

.... snip ....

Let me know if you have any tips....probably a small issue.  Thanks!

Hi Gabriel,

Finally a question I can easily answer! (I'll hopefully be getting to 
some of the more difficult ones piling up later today...)

I've had some success with Gordon McMillan's "Installer" with Vision Egg 
apps, but I haven't tried py2exe (although that has worked well for me 
for other scripts I've written).

To see the how I ran Installer (a while ago now!), you check out this 
script, which builds .exe files from most of the Vision Egg demos: 
http://cvs.sourceforge.net/viewcvs.py/visionegg/visionegg/build-win-exe-demos.py?view=markup

It's a little funky because it generates .exe files for each of many 
Vision Egg scripts, and tries to keep the common dependencies in other 
.dlls within the same directory.

Good luck, and if you have recipe for py2exe, I've be more than happy to 
include it with the Vision Egg source.

Cheers!
Andrew
