[visionegg] Re: py2exe and VisionEgg

Hi, Andrew,

The executable has a null response... it does nothing at all. Just tried your suggestion of creating the "missing files", seems to work (at least the build goes through flawless).

However, still no output upon running the executable. Task Manager in XP lists the process for the executable momentarily then it is gone. The original scripts themselves are still working fine through the python interpreter.

Do you recall any peculiarities or specifics for making win32 executables from VisionEgg scripts? It may likely be an Installer issue, since I just ran a "hello world" script (no includes) through and still no output when running the executable.

(NB: As I'm not particularly familiar with Installer, I simply modified your built-win-exe-demos.py script by changing the scripts_orig file list, but leaving the rest intact. I assume the script was written for Python 2.2 (as the "don't forget to copy PyWinTypes22.dll..." warning at the end suggests). I don't think this would cause any problems, though... I hope)

Next step is to trace through the Installer source and docs to see if I can find the problem....what fun!

Let me know if you have any suggestions on what might be holding the build up.

cheers!

p.s. Also tried using freezePython but that presents its own problems.




Hi Gabirel,

If you run the .exe from the command line, do you see any error messages?

Also, I see the following error in your log: "IOError: [Errno 2] No such file or directory: 'README-BINARY-DEMOS.txt'"
If you have a (dummy) file of that same name, does it work?

Let us know.

Cheers!
Andrew

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

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:

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

Hello all,

We're trying to run some standalone python scripts on some cluster pc's and found that py2exe (http://starship.python.net/crew/theller/py2exe/) would be ideal for this, as we're not allowed to alter the standard cluster pc disk image.

py2exe works great with simpler scripts but I have trouble getting all the dependencies set for a typical visionegg demo (given the numerous dependencies).

Anybody run across this with any luck?
