Troubles building with python3.5 #61

Closed iago-lito closed 8 years ago

iago-lito commented 8 years ago

Here is how I have tried to build the module:

git clone https://github.com/bastienleonard/pysfml-cython
cd pysfml-cython/
cd src/
cython -3 --cplus sfml.pyx
cd ..
sudo python3.5 setup3k.py build_ext  # error: command 'gcc' failed with exit status 1
./patch.py
sudo python3.5 setup3k.py build_ext # fails again

Here is the output of the last command:

If the build fails, run patch.py and try again

Have I done anything wrong? A similar thing seems to happen with python3.4 anyway.

I do have SFML installed:

During troubleshooting, I would like to use ancient pysfml binding, but I can't download it anymore. How is this repo related to that project? Do you know why is this link dead?

This is it, thank you for this precious binding :)

Hi,

This project hasn't been updated in a few years, so compilation with any recent version of SFML should fail. This seems to be the go-to Python binding now: https://github.com/Sonkun/python-sfml

I recently looked at the state of SFML and it seemed like it wouldn't be too much work to update the binding. However, I'm not sure there is any demand for it.

For the dead link see this issue: https://github.com/Sonkun/python-sfml/issues/124

Yeah, I've just noticed now.. Cheers :)
