Kivy for Python 3.3


F

fronagzen

Hello, first time poster here, and general newbie to Python.

I'm looking to write a program in Python, (and have in fact written most ofit by now,) and am trying to put together a GUI for it. Kivy looks very nice, particularly with the fact that it's supposed to be compatible with most platforms (including Android, which I would like to be able to use my program on in addition to running it on my desktop) with minimal hassle. However, its current iteration is Python 2.7 only, and I've only learned Python 3.3.

I suppose I could learn Python 2.7, but I don't really want to. (Nor rewrite my program.) I could wait for the next release of Kivy, but who knows when that will be?

In any case, it's apparently possible to pull and compile the development version of Kivy for 3.3: https://groups.google.com/forum/#!topic/kivy-dev/pRp_02jaJww/discussion, however, I haven't succeeded in getting it to work. I'm on a Windows machine, and after a good deal of wrangling, I'm getting:

I also tried to compile it with an Ubuntu virtual machine, but I failed hard on that since I'm not a native Linux user. Would anyone be able to help, either by suggesting how I can fix the above error, or, perhaps, by helpingme compile Kivy?

(I did post this on the Kivy group, but I've not gotten any response there.... The group's a bit dead.)

Hi

Have you tried asking on the kivy irc channel? (#kivy on freenode, or
http://webchat.freenode.net/?nick=kvuser.&channels=kivy&uio=d4)

The channel is fairly active, though you might have to wait a bit for a
response.

I'm not a Windows user myself, so unfortunately I can't help with the
issue directly.

Regards,

Last I looked, which was half a year ago, there was some Python 3
porting of Kivy underway, as you found yourself. If I were you, I would
get on IRC (I think it was #kivy on irc.freenode.net) and try to contact
the people there about the state of the Python 3 port. Just have some
patience, there aren't hundreds of people (yet), so getting an answer
could take some time.

'msvcr100' is the C runtime of MS Visual C++, I'm not sure if it is
required for building Python modules on MS Windows. Just removing it
from the commandline (or makefile) should tell you already.
Alternatively, ask The Internet(R), http://bugs.python.org/issue15315
could be an answer. ;)

Good luck!

It might help copying msvcr100.dll (from MS VC++ Redistributable
Package) to c:\python33\libs (or wherever your python install is). See

Thanks for the response, and I swear that I did try googling the error, butdidn't find anything. Oh well. Anyway, it seems that adding msvcr100.dll to my python3.3\libs has done something. I'm getting a different file not found message now:

Working on the reasoning that sticking the missing file into the python3.3\libs file worked, I tried adding the glew files (glew32.dll, glew32.lib, GL\glew and GL\wglew.h) there, however, it doesn't seem to have made a difference. And this I googled this before asking. Doesn't seem to be much.

Hi,

I can feel your pain beeing dragged into
compile-unknown-source-on-windows from an innocent looking python script
;) This time it's not the linker complaining but GCC (the compiler)
itself not being able to find the header file GL/glew.h. Headers are
searched in the so called "include path" which is specified in setup.py.
This link http://glew.sourceforge.net/install.html suggests glew.h is
part of VisualStudio, and has some other interesting information.

Thanks for the response.

After a bit of tinkering, I've finally managed to compile the blasted thing! I just straight up dumped Glew into the appropriate files for VS10, and used the VS10 compiler instead of mingw32- and it worked!
