Using the 2.0 installer here and pySFML 0.2.

I'm guessing the change in Keyboard (I read about it in another ticket) was recent and the SFML installer isn't up to date, so I'd need to build SFML from source or use pySFML 0.1.3?

[Xavura]

Answered my own question - yes I need to use 0.1.3. Presumably building SFML from source would also work.

[bastienleonard]

I'm going to create a branch that's compatible with the RC. I'll also upload compatible release. Thanks for reminding me :P

[Xavura]

Heh, no problem.

[bastienleonard]

Also, building pySFML from Git won't work because Git is intended to be in sync with the SFML repo. I'm not sure I will have the time to do the packaging until this weekend, we'll see.

[bastienleonard]

Mmh, just realized the previous post didn't make any sense so I reworded it. Also, I created the rc-compatible branch which should build against the SFML 2.0 RC. I'd be grateful if anyone could test it.

[Xavura]

Awesome, I'll test it soon.

[shizmob]

I just tested it and it compiled fine, gonna test run-time quality now.

Just downloaded RC 2.0 from here and the 2.0 RC compatible PySFML from here and I'm getting this exact same error as OP:

Same.

[bastienleonard]

I'm really busy because of work currently, I'll try to look into this tomorrow.

[Xavura]

Awesome, I look forward to testing it.

[bastienleonard]

Gah, again, I didn't have time yesterday. Sorry for the delay, hopefully I'll find the time when I'm back home. It should be a fast fix anyway.

[bastienleonard]

It looks like the sfml.cpp file included in the release doesn't match the source; if I generate it the binding works correctly. So if you have Cython installed, you can set USE_CYTHON = True in setup.py (or setup3k.py). Tomorrow I'll take the time to review the releases, figure out what went wrong and test them before making new ones. Again, sorry for the delay.

For Windows users, this shouldn't be a problem, as these installers are up to date and work correctly: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pysfml

[shizmob]

Oh yes, I'm terribly sorry for that -- I didn't include the new sfml.cpp in my commit/pull request.

[bastienleonard]

I uploaded new RC-compatible source releases. Let me know if you encounter any problems.

[FuzzWool]

I had a Backspace tantrum on my Mac, too. Just tried running this new release and everything appears to have clicked into place, as it works with all the tests and my Windows pySFML2 code. Thank you very much for this fix.

[bastienleonard]

I just realized that the master branch still had the RC keyboard constant, for some reason, which is pretty confusing. To be clear, in the C++ SFML 2 RC, the constant for back space is Back, and it was renamed to BackSpace pretty recently. This breaks compatibility, so I made a new branch, rc-compatible, that still references Back and will build correctly. This doesn't change the Python API; you should be able to use BACK_SPACE everywhere. The master branch is kept up to date and should build with the latest C++ SFML code from Git.

Another source of incompatibility is the removal of the default font. I decided to remove it in rc-compatible as well, because it seems more simple to keep the same API for both branches.
