pysfml2-cython
« Reply #90 on: February 03, 2012, 01:43:18 pm »
I'm having trouble getting pysfml2 to build. I'm on Mac OS X Lion using python2.7 via Macports. I've successfully installed SFML2 and been able to run examples but I when I try to build pysfml2 I get a bunch of warnings and a failure to find the sfml-[blah] libraries.

Code: [Select]

...tons and tons of warnings...
363 warnings generated.
/Developer/usr/bin/clang -fno-strict-aliasing -fno-common -dynamic -pipe -O2 -fwrapv -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I/opt/local/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c hacks.cpp -o build/temp.macosx-10.7-x86_64-2.7/hacks.o

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any thoughts on what I'm doing wrong?

Figured it out.

Though its not really detailed on the either the SFML2 or the PySFML2 install page, you need to make sure you uncheck the box saying build frameworks when you generate your unix make files in cmake for SFML2.

After that things work fine.

I found something that would probably be good to fix

http://www.sfml-dev.org/documentation/2.0/classsf_1_1Clock.php

In the documentation for SFML 2 it says Clock.restart() should return the time since the clock was started.

Can you make this return that time also? It should be a pretty quick fix.

Ok so i have built it in MinGW this time it builds, and i think it runs fine.

The newer version doesn't seem to want to play nicely with another cython module im using for speeding up openGL some. The older build worked fine with it. Any idea's?

Excuse me, but do this binding works with python3?
I'm just confused by the 'cython' word.
AFAIK Cython is just different interpreter for python, isn't it? or it provides a bit different syntax too?

Ok, for now i can just use the prebuilt version all im using now is clock window and event. I will need the Audio streaming stuff later on though. Will soon be looking into keyboard and joysticks too. Network would be useful at some point down the road but its not really needed for a while.


Keyboard and joysticks should work fine. Network classes aren't ported because their features are available in the Python standard library. I'll add streaming as soon as possible.

Thanks, I made the change as soon as I read your message.

It looks like it's mentioned here: http://www.sfml-dev.org/tutorials/2.0/compile-with-cmake.php

Quote
CMAKE_INSTALL_FRAMEWORK_PREFIX (Mac OS X only)
This is the install path for frameworks. By default, it is defined to the root library, i.e. /Library/Frameworks folder. As stated for CMAKE_INSTALL_PREFIX it is not mandatory to install files after compiling, but it is cleaner to install them.
This path is used to install on your system sndfile.framework (a required dependency not provided by Apple) and SFML as frameworks if BUILD_FRAMEWORKS is selected.

I've tried to use this module for OpenGL calls myself, so I need to know which tools you're using.
I now have a working Visual Studio installation, hopefully I'll be able to make it easier to build the module with it.

Cython is a tool used to create CPython 2/3 extension modules. I have modified the documentation to be more clear about that.

I have added a Windows installer for Python 2.7 32-bit. Feedback is welcome.
I have removed the source snapshot with Cython-generated files, as it was mainly intended to make the compilation easier for Windows users.

For version numbers, I think I'm just going to increase the revision number every time I generate a new installer. When SFML is released, I will use the same major and minor numbers as SFML, and I will use the revision number for pySFML-related changes. So if you're using SFML 2.1, you'll need pySFML 2.1.x.

By the way, I still have crashes at program exit (I was hoping that the problem comes from MinGW). Currently, I'm not focusing on it too much since it's not a big problem when you're trying out a library in its early stage.
I'm curious to know if everyone has this problem, and if it comes from SFML's cleanup or something else. I almost never have this kind of crash on GNU/Linux.

I have fixed the Python 3 build, but you need to call the patch.py script to fix a file generated by Cython. See the updated documentation : http://pysfml2-cython.readthedocs.org/en/latest/building.html#building-a-python-3-module

I also added Python 3 and 64 bits Windows installers.

I have renamed the module to sfml. It's more explicit and may avoid clashes.
If you want to keep it shorter, use “import sfml as sf” from now on.

Is there anything in pySFML 2.0 that doesn't map nicely to the C++ version? I am wanting to test it out, but the documentation is a bit lacking in specificity.

Read the tutorial for an overview. I'm eager to know if something important is missed out. I guess I should add a page for C++ developers as well.

I'm not sure if this has been mentioned already, but the module is missing a way to manipulate the audio 'listener'.

If it could be added, that would be nice, thanks.

Thanks for pointing that out, I've added it.
